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 EC with it’s low cobalt content and extra coarse, very uniform WC grain size distribution is the perfect powder for multiple mining and rock drilling applications. This material requires only short milling in the ready-to-press powder production and offers good sintered properties.
