Tungsten copper electric spark electrode is a two-phase structure pseudo alloy composed of tungsten element as the base and copper element as the auxiliary. It is made of fine high-purity tungsten powder and high-purity tungsten copper powder by the first-class process of mixed powder hydrostatic forming high-temperature sintering solution copper.
Tungsten rhenium alloy wire belongs to refractory materials and has good ductility and strength. Tungsten rhenium alloys have a high melting point of 3050 °C and a high temperature of recrystallization of 1900 °C which makes it used in aerospace and temperature measuring applications.
tungsten heavy alloys are the tungsten alloys consisting of W-Ni-Fe or W-Ni-Cu. The tungsten content varies from 90% to 98%. Nickel, iron and/or copper serve as a metal binder matrix,Tungsten nickel-iron alloy, also known as tungsten alloy, has many excellent properties such as high melting point, high density, good elongation capacity, and so on.
Tungsten was used extensively for the filaments of old-style incandescent light bulbs, but these have been phased out in many countries. This is because they are not very energy efficient; they produce much more heat than light.
