Key information:
Tungsten heavy alloys consist of 85～98% tungsten with balanced commonly nickel and iron or copper. The alloys
are made by liquid-phase sintering to give a structure consisting of almost pure tungsten particles in a matrix of
the alloy elements. Tungsten Heavy Alloys, with densities between 16.9 and 18.1 g/cm3, represent the heaviest
materials generally available to the engineer. It has excellent radiation resistance, thermal and electric
conductivities, corrosion resistance and machinable. We can offer tungsten alloys with tungsten contents ranging
from 85 to 98% with a range of physical and mechanical properties as well as non-magnetic W-Ni-Cu. We offer an
impressive variety of shapes, sizes and weights, ranging from grams to over 500 kg, as blanks as well as finished
tungsten parts.

Important:
We can produce heavy high alloys by MIM. MIM is fast growing to bridge the manufacturing gap which other metal
working technologies and shaping processes can not be fulfilled because of technology or cost.
MIM Advantages:
1.MIM process can produce more complex parts than either investment casting or traditional press and sinter
techniques.
2.The cost can be saved by eliminating machining operations.
3.Dimensions of MIM parts produced with our feedstock can be held to +/- 0.001～0.002" per inch.
4.MIM parts produced with our feedstock will have density levels between 97.5-99.5%. These levels typically exceed
traditional press and sinter techniques.
5.The tensile strengths, elongations and hardness are superior to traditional press and sinter techniques,
and comparable to investment casting or machine components.
