Bar and rod stock are available with ground surfaces and as sintered or swaged condition. Diameters range from 1 to 30 mm and up to 2000 mm long depending on size and conditioning. Large ranges of custom crucibles and single
crystal ingots are offered.
As high performance
materials, Tungsten-Copper
and Molybdenum-Copper
are characterized by
high thermal conductivity,
low thermal expansion and
high wear resistance
combined with excellent
electrical conductivity.
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 Electrical Application
Alloys and Properties: High Voltage Arc Contacts, Vacuum Contacts, Electrodes for Resistant Welding and Spark Erosion, Leaders for Steel Rolling, Dies for Casting, Balance Weights, Rocket Parts.
Tungsten-Copper for Electric Application
Tungsten-Copper high performance composites Tungsten-Copper high performance composites
for electrical applications are made from for electrical applications are made from
carefully controlled porous tungsten that is carefully controlled porous tungsten that is
vacuum infiltrated with molten copper. This vacuum infiltrated with molten copper. This
provides a superior electrical contact material provides a superior electrical contact material
that combines the refractory, long lasting wear that combines the refractory, long lasting wear
resistant properties of tungsten with the high resistant properties of tungsten with the high
thermal and electrical conductivity of copper. thermal and electrical conductivity of copper.

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.
