Description of

Tungsten-Copper Alloys  

            

These composites are made by infiltrating

porous tungsten or molybdenum with

molten copper in a vacuum. Thus

providing a direct copper path for heat or

electrical conductivity.

Tungsten-Copper for Heat Sinks

MIM is a fast growing manufacturing method that bridges the manufacturing gap that other metal working technologies and shaping processes cannot be fulfilled because of technology or cost. MIM can be a very cost effective method for producing large quantities of precision parts.

MIM Advantages

High Shape Complexity: MIM process can produce more complex parts than either investment casting or traditional press and sinter techniques.

Low Cost: Machining operations can be eliminated.

MIM Processing Why we comment and present MIM Processing?

Tight Tolerances: Dimensions of parts produced with our

feedstock can be held to +/- 0.001~0.002" per inch.

High Density: MIM parts produced with our feedstock will

have density levels between 97.5-99.5%. These l levels

typically exceed traditional press and sinter techniques.

High Performance: The tensile strengths, elongations

and hardness are superior to traditional press and sinter

techniques, and comparable to investment casting or

machine components.
