Tungsten-molybdenum and tungsten-molybdenum alloy properties
High temperature resistant metal, with good thermal conductivity, electric conductivity, low thermal expansion coefficient, high temperature strength, low vapor pressure and wear resistance and other characteristics, is an important material for electronic and power equipment manufacturing, metal material processing industry, glass manufacturing, high temperature furnace structural parts manufacturing, aerospace and national defense industry applications.
Tungsten and molybdenum are two kinds of high temperature resistant metals. Together, tungsten and molybdenum represent an industry, that is, refractory metal industry. Other refractory metals include niobium, zirconium, titanium, and hafnium, rather than an element. For industrial development has a great role, the current products are mainly used in argon arc welding machine on the electric electrode. China is a major producer of tungsten and molybdenum in the world, accounting for 80% of the world's exports. It is widely used in welding, electric light source, electronic devices, chemical industry, mining, metallurgy, shipbuilding, petroleum, aerospace and other industrial fields, and has a very broad prospect.
Tungsten-molybdenum and tungsten-molybdenum alloy have good thermal conductivity, electric conductivity, low thermal expansion coefficient, high temperature strength, low vapor pressure and wear resistance and other characteristics, and become the electronic and power equipment manufacturing industry, metal material processing industry, glass manufacturing, high temperature furnace structural parts manufacturing, aerospace and national defense industry applications of heavy materials. The application of molybdenum and molybdenum alloy in the above fields is mainly made by machining, forming, metal working and welding.
