Tungsten plate mainly used for electronic semiconductor, Insulation panel of High Temperature Furnaces Heating Apparatus. With stable performance,the maximum withstand temperature of up to 3000 °C or more.
Tungsten is one of our main product.
It has the highest melting point (3410°C) of the four common refractory metals.
with a density of 19.3 gm/ cc, it is only surpassed by rhenium and osmium in weight.
Tungsten has a long history of use for filaments in the lamp industry.
Tungsten has the best high-temperature strength of all the refractory metals.
For this reason, it is used in very high temperature vacuum furnaces
