Benchmark's naturally inert Cobalt contains a special blend of Cobalt and other alloys that exude extremely high luster and reliable strength. Because it is also hypoallergenic, scratch resistant and biocompatible, it has been used heavily in medical applications. Cobalt, unlike Tungsten, is shatter proof.
Cobalt, often compared to platinum or palladium in color, is a bright white metal that is highly scratch resistant, doesn't chip or shatter and is hypo-allergenic. With both the feel and weight of platinum, cobalt is a cost-effective alternative. Cobalt neither fades nor tarnishes and can be easily polished using platinum polishing techniques.
