About Chromium Ring

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

Chromium Bohr ModelThe number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electron configuration is [Ar] 3d5 4s1. Louis Nicolas Vauquelin first discovered chromium in 1797 and first isolated it the following year. The chromium atom has a radius of 128 pm and a Van der Waals radius of 189 pm. In its elemental form, chromium has a lustrous steel-gray appearance. Elemental ChromiumChromium is the hardest metallic element in the periodic table and the only element that exhibits antiferromagnetic ordering at room temperature, above which it transforms into a paramagnetic solid. The most common source of chromium is chromite ore (FeCr2O4). Due to its various colorful compounds, Chromium was named after the Greek word 'chroma.' meaning color.
