| Copper Boron 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.
Copper is a Block D, Group 11, Period 4 element. The number of electrons in each of Copper's shells is 2, 8, 18, 1 and its electronic configuration is [Ar] 3d10 4s1. In its elemental form copper's CAS number is 7440-50-8. The copper atom has a radius of 127.8 .pm and it's Van der Waals radius is 140.pm. Copper is an essential trace element in animals and plants, but in excess copper is toxic. Due to its high electrical conductivity, large amounts of copper are used by the electrical industry for wire. Of all pure metals, only silver has a higher electrical conductivity. Copper is also resistant to corrosion caused by moisture, making it a widely used material in pipes, coins, and jewelry. Copper is often too soft for its applications, so it is incorporated in numerous alloys. For example, brass is a copper-zinc alloy, and bronze is a copper-tin alloy. Copper sulfate (CuSO 4·H2O), also known as blue vitrol, is the most well-known copper compound. It is used as an agricultural poison, an algicide, and as a pigment for inks. Cuprous chloride (CuCl) is a powder used to absorb carbon dioxide (CO2). Copper cyanide (CuCN) is often used in electroplating applications. Copper is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Copper was first discovered by Early Man. The origin of the word copper comes from the Latin word 'cuprium' which translates as "metal of Cyprus". Cyprus, a Mediterranean island, was known as an ancient source of mined copper. See Copper 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 is not toxic. 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.
