Introduction to tungsten and molybdenum
Tungsten and molybdenum are two high temperature resistant metals. Tungsten and molybdenum together represent an industry, the refractory industry. Other refractory metals are niobium, zirconium, titanium and hafnium, not just an element. has a great effect on industrial development, and at present the products are mainly used for charged electrodes on argon arc welding machine. China is the world's largest producer of tungsten and molybdenum, accounting for 80 percent of the world's exports.
Tungsten molybdenum and tungsten molybdenum alloys have good thermal conductivity, low thermal expansion coefficient, high temperature strength, low steam pressure and wear resistance, and become materials for electronic and electrical equipment manufacturing, metal material processing industry, glass manufacturing, high temperature furnace structural accessories manufacturing, aerospace and defense industry applications. Molybdenum and molybdenum alloys are mainly used in the above fields through machining, forming and metal processing and welding.
