Material Introduction

Tungsten and Tungsten Alloy

Tungsten features high melting point, elastic modulus, good electrical and thermal conductivity, excellent high-temperature strength and low thermal expansion coefficient; tungsten alloy is formed by adding other alloying elements to pure tungsten as the matrix, and the main elements include titanium (Ti), zirconium (Zr), hafnium (Hf), iron (Fe), nickel (Ni), copper (Cu), and rare earth elements. Tungsten and tungsten alloys have the characteristics of high melting point, high hardness, high elastic modulus, high temperature performance, low resistivity, high thermal expansion coefficient, electronic work function, etc., and have been widely applied in the fields such as high temperature furnace, electronics, ordnance industry etc.
