With Cobalt

Cups, Crucibles, Cans

Cobalt is a reflective, lustrous and hard alloying element resembling iron and nickel that is used in high- temperature, wear-resistant and corrosion-resistant alloys. Some of these alloys are biocompatible and are used for orthopedic implants. Its cobalt blue tint enables it to be used most commonly for paint pigments.
