Iron Manangese Chromium Molybdenum Nitrogen is one of numerous metal alloys sold by American Elements under the tradename AE Alloys™. Generally immediately available in most volumes, AE Alloys™ are available as bar, Ingot, ribbon, wire, shot, sheet, and foil. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, targets for thin film deposition, and pellets for chemical vapor deposition (CVD) and physical vapor deposition (PVD) applications.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Primary applications include bearing assembly, ballast, casting, step soldering, and radiation shielding. Stainless steel used in medical applications is made out of several components: chromium, nickel and molybdenum. These bio-medical materials are biocompatible, resistant to corrosion, degradation, and wear, and they have mechanical properties that duplicate the structures they are intended to replace.
Iron is a Block D, Group 8, Period 4 element. The number of electrons in each of Iron's shells is 2, 8, 14, 2 and its electronic configuration is [Ar] 3d6 4s2. In its elemental form iron's CAS number is 7439-89-6. The iron atom has a radius of 124.1.pmmine iand it's Van der Waals radius is 200.pm. Iron is not toxic. Iron is the most commonly used metal for commercial applications due to its hardness, historical availability and low cost. Once used on its own, it is now alloyed with nickel and other elements to produce steel and other high strength, non-corrosive structural metals. Iron as a metal and as its many compounds has numerous uses. It is a primary colorant in glass and ceramics. It is a catalyst. It is the basis for low grade magnets and because of its magnetic properties is used extensively in memory tape. Recent applications for Iron nanoparticles include in water treatment of carbon tetrachloride in contaminated groundwater, magnetic data storage and resonance imaging (MRI) and in certain alloy and catalyst applications. Iron can also be introduced into processes using iron foil, pellets, rod and wire by thin film 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), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Iron 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. Iron was first discovered by Early Man.See Iron research below.
Manganese is a Block D, Group 7, Period 4 element. The number of electrons in each of Manganese's shells is 2, 8, 13, 2 and its electronic configuration is [Ar] 3d5 4s2. In its elemental form manganese's CAS number is 7439-96-5. The manganese atom has a radius of 136.7.pm and it's Van der Waals radius is 200.pm. Manganese in excess is toxic, in particular the inhalation of manganese in powder or dust form. Manganese metal is a key component of aluminumalloys. Manganese oxide is used in dry cell batteries. Manganese is used in steel production to remove sulfur and oxygen. Manganese is the colorant in natural amethyst stones and is used in glass and ceramics to also create the amethyst color. It is used like the element cerium to "decolorize" glass by offsetting the green from impurities of ferric ions. Permanganate is a powerful oxidizing agent and is used in medicine. It is added as a nutritional supplement for both human and animal consumption. Recently, the oxide in the form of various perovskite structures have demonstrated applications in oxygen generation and solid oxide fuel cells. Manganese was first discovered by Johann Gahn in 1774. The name Manganese originates from the Latin word mangnes meaning magnet. See Manganese 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.

Iron is a Block D, Group 8, Period 4 element. The number of electrons in each of Iron's shells is 2, 8, 14, 2 and its electronic configuration is [Ar] 3d6 4s2. In its elemental form iron's CAS number is 7439-89-6. The iron atom has a radius of 124.1.pmmine iand it's Van der Waals radius is 200.pm. Iron is not toxic. Iron is the most commonly used metal for commercial applications due to its hardness, historical availability and low cost. Once used on its own, it is now alloyed with nickel and other elements to produce steel and other high strength, non-corrosive structural metals. Iron as a metal and as its many compounds has numerous uses. It is a primary colorant in glass and ceramics. It is a catalyst. It is the basis for low grade magnets and because of its magnetic properties is used extensively in memory tape. Recent applications for Iron nanoparticles include
in water treatment of carbon tetrachloride in contaminated groundwater, magnetic data storage and resonance imaging (MRI) and in certain alloy and catalyst applications. Iron can also be introduced into processes using iron foil, pellets, rod and wire by thin film 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), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Iron 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. Iron was first discovered by Early Man.See Iron research below. 
Manganese is a Block D, Group 7, Period 4 element. The number of electrons in each of Manganese's shells is 2, 8, 13, 2 and its electronic configuration is [Ar] 3d5 4s2. In its elemental form manganese's CAS number is 7439-96-5. The manganese atom has a radius of 136.7.pm and it's Van der Waals radius is 200.pm. Manganese in excess is toxic, in particular the inhalation of manganese in powder or dust form. Manganese metal is a key component of aluminum alloys. Manganese oxide is used in dry cell
batteries. Manganese is used in steel production to remove sulfur and oxygen. Manganese is the colorant in natural 
amethyst stones and is used in glass and ceramics to also create the amethyst color. It is used like the element cerium to "decolorize" glass by offsetting the green from impurities of ferric ions. Permanganate is a powerful oxidizing agent and is used in medicine. It is added as a nutritional supplement for both human and animal consumption. Recently, the oxide in the form of various perovskite structures have demonstrated applications in oxygen generation and solid oxide fuel cells. Manganese was first discovered by Johann Gahn in 1774. The name Manganese originates from the Latin word mangnes meaning magnet. See Manganese 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.
