Product Description

WLCo 6 cobalt based rod is the most widely used of the cobalt alloys. It is regarded as the industry standard for general-purpose wear resistance applications, has excellent resistance to many forms of mechanical and chemical degradation over a wide temperature range, and retains a reasonable level of hardness up to 500°C (930°F)

Another similar type is Co 6H rod, which has higher hardness.
