China Tungsten Furnace Parts Components for Electron Tubes

Of all matals in pure from,tungsten has the highest melting point,lowest vapor pressure and the highest tensile strength.It is the ideal material for ultra high temperature and high vacuum applications.
Tungsten has the lowest coefficient of thermal expansion(CTE)of any pure metal,its CTE match well with semiconductor material,such as Si,GaN,GaAs,Al2O3,and it is stable aPump & Vacuum Equipment t high temperature,make it the ideal material for electronic packaging and seals.
Tungsten has a Machine Hardware lower electrical resistivity than other refractory metals,but it will increase with temperature,this property is critical fAlarm & Security Systems or high temperature furnace applications.
