Method and tool of tungsten/heavy metal alloy for hot-forging copper and copper alloys

Method and tool of tungsten/heavy metal alloy for hot-forging copper and copper alloys

The tungsten/heavy metal alloy is suitable for tools such as extrusion dies and extrusion mandrels for the hot-forming of copper and copper alloys. The novel alloy consists of 80 to 89.9% by weight of tungsten, 2 to 7% by weight of chromium, and a remainder of binder metal. The use of the novel allo...

description The tungsten/heavy metal alloy is suitable for tools such as extrusion dies and extrusion mandrels for the hot-forming of copper and copper alloys. The novel alloy consists of 80 to 89.9% by weight of tungsten, 2 to 7% by weight of chromium, and a remainder of binder metal. The use of the novel alloy primarily results in a considerably reduced formation of grooves on the surface of the forming tools.
