1,Description:
Tungsten alloys, also known as tungsten heavy alloys (WHAs) or tungsten-based alloys, are composite materials consisting primarily of tungsten with the addition of one or more metallic elements. Here is an English description of tungsten alloys:
Tungsten alloys are dense and high-strength materials that exhibit exceptional mechanical properties. They are composed of tungsten as the primary constituent, typically ranging from 85% to 98% by weight, with the remaining portion consisting of other metals such as nickel (Ni), copper (Cu), iron (Fe), and molybdenum (Mo).
The addition of these metallic elements to tungsten enhances the ductility, machinability, and formability of the alloy, while still maintaining the desirable properties of tungsten, such as high density, high melting point, and excellent thermal and electrical conductivity.
Tungsten alloys are renowned for their high density, often surpassing that of lead and steel. This property makes them ideal for applications requiring weight concentration, such as aerospace components, balance weights, radiation shielding, and kinetic energy penetrators.
