5) Tungsten tubes process and usage:
Process: APT--powder--reduction suppression (sintering/car processing)products--rooted (spin forging/rolling)--stretching--tube
Usage: Because of the tungsten high melting point (3400 ° C), high-density (19.3 g/cm3), sound velocity (4.03 km/s),tungsten tube has good ductility characteristics of pure metal state,and tungsten alloy state is widely used in modern technology, alloy is the main is a state of alloy steel, with tungsten carbide based hard alloy, and the strong heat resistant alloy alloy.
6) Tungsten tubes application:
Tungsten crucible and tubes can be used for sapphire crystal growth and rare-earth melting due to their high temperature resistance, low pollution and other excellent characteristics.
