Ⅰ What is Tungsten Alloy?

There are two definitions of tungsten alloy: (1) tungsten alloy in a broad sense: metal materials containing tungsten are collectively called tungsten alloy, such as tungsten-iron alloy, tungsten-copper alloy, tungsten-nickel alloy and cemented carbide; (2) Tungsten alloy in a narrow sense: an alloy material composed of tungsten as a matrix material and a small amount of metal binders such as nickel, copper, iron, cobalt, molybdenum and chromium, also known as high specific gravity tungsten alloy or high density tungsten alloy or heavy alloy.

Tungsten trioxide (WO 3), also known as yellow tungsten oxide, is an oxide of tungsten and an N-type semiconductor as well. These two characteristics make tungsten trioxide not only have high density, high boiling point and high melting point, but also have catalytic, optical and electrical properties.

Tungsten Trioxide, also known as tungsten oxide (WO 3), has been widely used in many fields such as petrochemical industry, photoelectric information, national defense and military industry because of its special properties such as catalysis, optics and electricity.

Tungsten trioxide, also known as tungsten anhydride (WO₃), is a yellow powder, insoluble in water and alkali, and slightly soluble in acid. Because of its good optical, electrical and gas sensitive properties, it is widely used in life, chemical industry, medical treatment and military affairs.
