Tungsten&molybdenum tubes processing technic: 

1. Process: APT--powder--reduction suppression (sintering/car processing)products--rooted (spin forging/rolling)--stretching--tube
2. Usage: Because of the tungsten high melting point (3400 ° C), high-density (19.3 g/cm3), sound velocity (4.03 km/s), 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. 
3. Size: OD(3.5-350)*W(0.5-50)*L

We also can produce tungsten boat, tungsten crucibles, tungsten funnels, tungsten barrel, tungsten tubes and various kinds of special liquid- flow hole panel, etc.
