Use Of High Temperature Die Material & Hot Dies For High Pressure Die Casting Pure Copper & Copper Alloys

Abstract Little use has been made of pressure die casting for the manufacture of copper or copper alloy parts due in large part to poor economics resulting from short die life in casting these high melting metals. A research program initiated in 1997 was driven by the promise of a signifi cant increase in the
