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.

Technological properties

Property
Application areas	Powder grade EC20L was developed for use in a wide range of tooling products, for example road construction or coal mining tools, indexable inserts, and wear parts.
Other	Grade EC20L shows an extremely coarse WC grain size and thanks to Tikomet’s unique recycling process, the powder has a very narrow WC grain size distribution. Fully dense sintered microstrutures can be achieved even at low cobalt content.
