W70Cu30 Alloy Plates

W70Cu30 is a tungsten-copper alloy composed of 70% tungsten and 30% copper, classified as a typical composite material. Within the tungsten-copper alloy system, it is categorized as a "balanced alloy" or "high-tungsten alloy," with properties that bridge the gap between the extreme characteristics of pure tungsten and the excellent electrical conductivity of high-copper alloys. By combining tungsten's high melting point, high hardness, and low coefficient of thermal expansion with copper's high electrical conductivity, high thermal conductivity, and good ductility, it holds significant application value across numerous industrial sectors.
