Nickel Chromium Molybdenum Boron is one of numerous metal alloys sold by American Elements under the tradename AE AlloysT . Nickel Chromium Molybdenum Boron powder is used in corrosion resistant coatings. American Elements specializes in producing high purity Nickel Chromium Molybdenum Boron powder with the smallest possible average grain sizes for use in preparation of pressed and bonded sputtering targets and in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles (See also Nanotechnology Information and Quantum Dots ) also produce very high surface areas. Our standard Powder particle sizes average in the range of - 325 mesh, - 100 mesh, 10-50 microns and submicron (< 1 micron). We can also provide many materials in the nanoscale range. See research below. We also produce Nickel as rod, ingot, pieces, pellets, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request
Nickel is a Block D, Group 4, Period 4 element. The number of electrons in each of Nickel's shells is 2, 8, 16, 2 and its electronic configuration is [Ar]3d8 4s2. In its elemental form nickel's CAS number is 7440-02-0. Nickel is sometimes found free in nature but is more commonly found in ores. The nickel atom has a radius of 149.pm and it's Van der Waals radius is 163.pm. Nickel and its compounds are considered to be carcinogenic. Nickel carbonyl is a very toxic gas. It is extensively alloyed with iron, chromium, molybdenum, tungsten and other metals produce stainless and other anti-corrosive steel and other corrosion-resistant alloys. It is highly electronically conductive and has many applications as a result. It is the basis of the nickel hydride battery. Most recently, its conductive properties have made it an ideal component for ceramic anode formulations used in oxygen generation and solid oxide fuel cell applications. Catalytic nickel is used to hydrogenate vegetable oils. Nickel additions to glass and ceramic glazes impart a bright green. It is also used in pigments for this purpose. Nickel information, including Technical Data, Safety Data and its high purity properties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. Nickel was first discovered by Alex Constedt in 1751. The name originates from the German word 'kupfernickel' which means false copper from the illusory copper color of the ore. See Nickel research below.
Chromium is a Block D, Group 6, Period 4 element. The number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electronic configuration is [Ar] 3d5 4s1. In its elemental form chromium's CAS number is 7440-47-3. The chromium atom has a radius of 124.9.pm and it's Van der Waals radius is 200.pm. Hexavalent chromium is toxic. Chromium is highly resistant to corrosion. This has led to its use in numerous alloying and steel producing applications. When chromium is added to glass or ceramic glazes, it produces a brilliant green. Chromium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. It is also used as a paint pigment for this purpose.Although chromium metal is an essential trace element, hexavalent chromium (Cr(VI)) is especially toxic and carcinogenic. Recently, chromites have formed the basis for cathode compositions for oxygen generation and fuel cell applications. Chromium information, including Technical Data, Safety Data and its High Purity properties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. Chromium was first discovered by Anders Ekeberg in 1802. Due to its various colorful compounds, Chromium was named after the Greek word 'chroma' meaning color. See Chromium research below.
Molybdenum is a Block D, Group 6, Period 5 element. The number of electrons in each of Molybdenum's shells is 2, 8, 18, 13, 1 and its electronic configuration is [Kr] 4d5 5s1. In its elemental form molybdenum's CAS number is 7439-98-7. The molybdenum atom has a radius of 136.3.pm and it's Van der Waals radius is 200.pm. Molybdenum is toxic unless it is in small quantities. Molybdenum has the third highest melting point of any element, exceeded only by tungsten and tantalum. Molybdenum is a catalyst in the oil refining. It has many other applications, including in catalysts, pigments, corrosion inhibitors and lubricants. It has a very high elastic modulus. Molybdenum is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. It is used in steel alloys to add hardness and raise melting points. It is a component in Hastelloys brand steel. Molybdenum is used in nuclear reactors and aerospace components. Molybdenum was first discovered by Carl Wilhelm in 1778. The origin of the name Molybdenum comes from the Greek word molubdos meaning lead. See Molybdenum research below.
Boron is a Block P, Group 13, Period 2 element. The number of electrons in each of Boron's shells is 2, 3 and its electronic configuration is [He] 2s2 2p1. In its elemental form boron's CAS number is 7440-42-8. The boron atom has a radius of 79.5.pm and it's Van der Waals radius is 200.pm. Boron has an energy band gap of 1.50 to 1.56 eV, which is higher than that of either silicon or germanium. Optical characteristics include transmitting portions of the infrared. Boron is a poor conductor of electricity at room temperature but a good conductor at high temperature. Boron in its elemental form is not toxic. Amorphous boron is used in pyrotechnic flares to provide a distinctive green color, and in rockets as an igniter Boric acid is also an important boron compound with major markets in textile products. Boron compounds are also extensively used in the manufacture of borosilicate glasses. The isotope Boron-10 is used as a control for nuclear reactors, as a shield for nuclear radiation, and in instruments used for detecting neutrons. Boron nitride has remarkable properties and can be used to make a material as hard as diamond. The nitride also behaves like an electrical insulator but conducts heat like a metal. Boron also has lubricating properties similar to graphite. Boron was first discovered by Sir Humphry Davy and J.L Gay-Lussac in 1808. The name Boron originates from a combination of carbon and the Arabic word 'buraqu meaning borax. See Boron research below.

Nickel is a Block D, Group 4, Period 4 element. The number of electrons in each of Nickel's shells is 2, 8, 16, 2 and its electronic configuration is [Ar]3d8 4s2. In its elemental form nickel's CAS number is 7440-02-0. Nickel is sometimes found free in nature but is more commonly found in ores. The nickel atom has a radius of 149.pm and it's Van der Waals radius is 163.pm. Nickel and its compounds are considered to be carcinogenic. Nickel carbonyl is a very toxic gas. It is extensively alloyed with iron, chromium, molybdenum, tungsten and other metals produce stainless and other anti-corrosive steel and other corrosion-resistant alloys. It is highly electronically conductive and has many applications as a result. It is the basis of the nickel hydride battery. Most recently, its 
conductive properties have 
made it an ideal component for ceramic anode formulations used in oxygen generation and solid oxide fuel cell applications. Catalytic nickel is used to hydrogenate vegetable oils. Nickel additions to glass and ceramic glazes impart a bright green. It is also used in pigments for this purpose. Nickel information, including Technical Data, Safety Data and its high purity properties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. Nickel was first discovered by Alex Constedt in 1751. The name originates from the German word 'kupfernickel' which means false copper from the illusory copper color of the ore. See Nickel research below.
Chromium is a Block D, Group 6, Period 4 element. The number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electronic configuration is [Ar] 3d5 4s1. In its elemental form chromium's CAS number is 7440-47-3. The chromium atom has a radius of 124.9.pm and it's Van der Waals radius is 200.pm. Hexavalent chromium is toxic. Chromium is highly resistant to corrosion. This has led to its use in numerous alloying and steel producing applications. When chromium is added to glass or ceramic glazes, it produces a brilliant green. Chromium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. It is also used as a paint pigment for this purpose.Although chromium metal is an essential trace element, hexavalent 
chromium (Cr(VI)) is especially toxic and carcinogenic. Recently, chromites have formed the basis for cathode compositions 
for oxygen generation and fuel cell applications. Chromium information, including Technical Data, Safety Data and its High Purity properties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. Chromium was first discovered by Anders Ekeberg in 1802. Due to its various colorful compounds, Chromium was named after the Greek word 'chroma' meaning color. See Chromium research below.
Molybdenum is a Block D, Group 6, Period 5 element. The number of electrons in each of Molybdenum's shells is 2, 8, 18, 13, 1 and its electronic configuration is [Kr] 4d5 5s1. In its elemental form molybdenum's CAS number is 7439-98-7. The molybdenum atom has a radius of 136.3.pm and it's Van der Waals radius is 200.pm. Molybdenum is toxic unless it is in small quantities. Molybdenum has the third highest melting point of any element, exceeded only by tungsten and tantalum. Molybdenum is a catalyst in the oil refining. It has many other applications, including in catalysts, pigments, corrosion inhibitors and lubricants. It has 
a very high elastic modulus. Molybdenum is available
as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. It is used in steel alloys to add hardness and raise melting points. It is a component in Hastelloys brand steel. Molybdenum is used in nuclear reactors and aerospace components. Molybdenum was first discovered by Carl Wilhelm in 1778. The origin of the name Molybdenum comes from the Greek word molubdos meaning lead. See Molybdenum research below. 
Boron is a Block P, Group 13, Period 2 element. The number of electrons in each of Boron's shells is 2, 3 and its electronic configuration is [He] 2s2 2p1. In its elemental form boron's CAS number is 7440-42-8. The boron atom has a radius of 79.5.pm and it's Van der Waals radius is 200.pm. Boron has an energy band gap of 1.50 to 1.56 eV, which is higher than that of either silicon or germanium. Optical characteristics include transmitting portions of the infrared. Boron is a poor conductor of electricity at room temperature but a good conductor at high temperature. Boron in its elemental form is not toxic. Amorphous 
boron is used in pyrotechnic flares to provide a distinctive green color, and in rockets as an igniter Boric acid is also an important boron compound with major markets in textile products. Boron compounds are also extensively used in the manufacture of borosilicate 
glasses. The isotope Boron-10 is used as a control for nuclear reactors, as a shield for nuclear radiation, and in instruments used for detecting neutrons. Boron nitride has remarkable properties and can be used to make a material as hard as diamond. The nitride also behaves like an electrical insulator but conducts heat like a metal. Boron also has lubricating properties similar to graphite. Boron was first discovered by Sir Humphry Davy and J.L Gay-Lussac in 1808. The name Boron originates from a combination of carbon and the Arabic word 'buraqu meaning borax. See Boron research below.
