Product Description
Xi'an Kefeng Powder Metallurgy is a professional Chinese tungsten plant. Pure tungsten is a hard metal from steel gray to tin white, tungsten with high purity can be sawed by swaging, pure tungsten is very fragile and difficult to be machined. Shapes can be processed in foil, strip, sheet, plate, wire, rod, bar, tubing, blanks, crucibles as well as semi-finished & finished parts, customs sizes.Pure tungsten can be very difficult to fabricate for its high hardness and low ductility. It is a strong, hard, crack-sensitive metal that is usually brittle at room temperature. It requires special handling and skill beyond that
necessary from most metals and alloys. The best method for machining that involves metal removal is EDM.
In general the pure tungsten products can be finished as: grinding, forming, joining, milling, riveting, spinning, stamping, and turning.
Characteristics and features
The pure tungsten features the high melting point and density and low vapor pressure that offer exceptionally high strength and good electrical resistivity at very high temperatures.. Tungsten' high density gives it a capacity to absorb radioactive radiation. It is widely used as a additives to steel to enhance physical properties and an alloywith nickel, copper and iron to provide high density machinable materials.
Application
Kefeng's pure tungsten Wire has been used for filaments in the lamp industry. It offers exceptionally high strength at very high temperatures thanks to its best high temperature strength of the four common refractory metals. Its high temperature strength, combined with its good electrical resistivity, have made it a popular choice for many applications. Tungsten is used for heating elements in vacuum furnaces that exceed the temperatures of molybdenum and tantalum as well as other heater applications.
