American Elements specializes in producing high purity Copper Circles with the highest possible densityand smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical High Purity (99.99%) Metallic Circlevapor deposition (PVD) display and optical applications. Our standard Circle sizes range from 1" to 8" in diameter and from 2mm to 1/2" thick. We can also provide Circles outside this range. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar, or plate form, as well as other machined shapes and through other processes such as nanoparticles () and in the form of solutions and organometallics.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. We also produce Copper as rod, pellets, powder, pieces, granules, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Copper Bohr ModelCopper (Cu) atomic and molecular weight, atomic number and elemental symbolCopper (atomic symbol: Cu, atomic number: 29) is a Block D, Group 11, Period 4 element with an atomic weight of 63.546. The number of electrons in each of copper's shells is 2, 8, 18, 1 and its electron configuration is [Ar] 3d10 4s1. The copper atom has a radius of 128 pm and a Van der Waals radius of 186 pm. Copper was first discovered by Early Man prior to 9000 BC. In its elemental form, copper has a red-orange metallic luster appearance. Elemental Copper Of all pure metals, only silver has a higher electrical conductivity.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.
