Cobalt alloy extrusion die inserts are specially designed for brass and copper extrusion processes. With excellent compressive strength, high-temperature red hardness, wear resistance, and oxidation resistance, cobalt alloy inserts maintain dimensional stability and extend die service life.

The selection of extrusion die material is critical to ensure performance, durability, and cost-efficiency in continuous extrusion processes. Cobalt-based alloys such as ST 12 are ideal for dies due to their exceptional wear resistance, high-temperature strength, and anti-adhesion properties, making them especially suitable for copper and aluminum extrusion applications.
