Safety Data Sheet

Osmium RingOsmium Rings can be customized in width, thickness, and ring diameter. Osmium rings may have a custom shape hole and may be open or closed. American Elements specializes in producing high purity uniform shaped Osmium rings. American Elements offers custom rings with annealed or hard tempers and will meet most of the common Milspec or ASTM standards. Osmium rings are hollow, circular pieces of metal and can be produced in custom sizes. In addition to standard alloys, American Elements also specializes in corrosiun resistant alloys, high temperature applications, and custom shapes and forms including custom inside and outside dimensions and threading. American Elements also produces Osmium as rod, ingot, powder, pieces, disc, granules, wire, and in compound forms, such as oxide. Osmium rings can be used as components in several applications.

Osmium (Os) atomic and molecular weight, atomic number and elemental symbolOsmium (atomic symbol: Os, atomic number: 76) is a Block D, Group 8, Period 6 element with an atomic weight of 190.23.Osmium Bohr Model The number of electrons in each of osmium's shells is [2, 8, 18, 32, 14, 2] and its electron configuration is [Xe] 4f14 5d6 6s2. The osmium atom has a radius of 135 pm and a Van der Waals radius of 216 pm. Osmium was discovered and first isolated by Smithson Tennant in 1803. Elemental Osmium In its elemental form, osmium has a silvery blue cast apperance. Osmium has the highest melting point and the lowest vapor pressure of any of the platinum group of metals; it is also the densest naturally ocurring element.. Osmium is the least abundant stable element in the earth's crust. It is found in the alloys osmiridium and iridiosmium and as a free element. The origin of the name Osmium comes from the Greek word "osme," meaning a smell or odor.
