Heavy Tungsten Alloy bears the high density ranging 17.0-18.8g/cc (90-98W) with the components of W-Ni-Cu, W-Ni-Fe Or W-Ni-Cu-Fe and etc. These heavy tungsten metal have very high melting points and have a density twice that of steel and are more than 50% heavier than lead.meanwhile,it's an excellent ductile material, according to modern powder metallurgy new technology,these tungsten alloy could be strengthen and gained long lifespan used in many industries, such as aerospace, electronic and electric light source, automobile, medical, oil exploration, military and so forth. Among metals, tungsten have the highest melting points , it is a significant refractory metal and keep good high temperature strength; heavy tungsten alloy bears high density, very high melting points, excellent creep resistance, heat conductivity, as well as electronic emission .tungsten alloys is an optimal counterweight material, alloy addition, die casting mould, radiation shielding.

1 Tungsten heavy alloy grade the charting covers four grades of the machinable ,high density tungsten base metal who produced by of metal powder metallurgy pressing and sintering of which the composition is mainly tungsten. This kind of tungsten heavy alloy materials may be used for spare parts or be used for parts that may be coated with other materials for protection against corrosion and abrasion.

2 application -parts made from tungsten alloy material are intended for uses such as weights or counter balances in static or dynamic balancing high speed rotating inertia system, radiation shielding ,hypervelocity impact and shock absorption.

3 For special unique application, properties or requirements may be important. These heavy tungsten alloys may contain elements which make them magnetic. Where freedom from magnetic it should be point out and choose non magnetic tungsten heavy alloy material in the process of production. non magnetic feature is defined as material having a maximum magnetic permeability of 1.05.
