New and innovative formulations of TC powders for Koner drawing dies

In recent years, Koner has studied and researched new formulations of TC powders containing special additives for the production of drawing dies, with the aim of increasing their wear resistance and extending work-life.

The new formulations enhance die hardness without affecting their toughness. The studies have led to the production of a new powder suitable for drawing high carbon wire, with a hardness of 90.5 HRA. This solution has delivered excellent results in the production of PC wire / PC strand / ropes, increasing die life by an average of 20%.

Koner has also developed a new powder for drawing low carbon wire, with a hardness of 94.2 HRA. The results in the production of welding wire have been excellent, increasing die life by 30%.

As shown in the photos, the micro-structure reveals a homogeneous distribution of the tungsten carbide grades within the cobalt matrix; this makes it possible, together with the additives included in the formulation, to significantly increase the wear resistance. Furthermore, the improved wear resistance leads to both ecological as well as economic benefits, since the same amount of drawn wire requires a lower consumption of mineral resources, with significant advantages for the customer and the environment.

After an extensive trial stage at some international customers of the TKT Group, the products have been approved with a high level of satisfaction and are now part of Koner’s standard production range.

The company intends to continue investing in the R&D of these innovative TC powders to align its offer with the increasingly high quality expectations of the market.
