Description

The zinc process is an environmentally friendly way to reclaim tungsten carbide-cobalt from used hard materials, such as cutting inserts, milling tools or other hard material compacts. This secondary raw material stream provides cost-effective and reliable high quality tungsten carbide powder grades. GTP's subsidiary Tikomet has consistently made improvements to the zinc reclaim process for more than two decades. Switch to an environmentally friendly raw material source and rely on our recycling experience.

Application areas

Powder grade I was developed for use in a wide range of tooling products, indexable inserts, woodworking tools or wear parts.

Other

Grade I has a tighter specification in cubic carbides and cobalt content compared to grade TS, as well as a significantly lower specification for its aluminium content. The small amount of 1-2 μm sized cubic carbides increases the hardness and decreases the density of the material. Thanks to the fine particle size of the powder, milling characteristics are excellent and comparable to virgin WC-Co powders.
