Copper Tungsten, Copper Molybdenum Heatsinks Supplier In China

Copper tungsten Alloy (W-Cu) is the composite of tungsten and copper which own it excellent performance of tungsten and copper. It is used widely in such industries as engine, electric power, electron, metallurgy, spaceflight and aviation.

Tungsten copper heat sink is a composite of tungsten and copper. The coefficient of thermal expansion (CTE) of the composite can be designed by controlling the content of tungsten, matching that of the materials, such as Ceramics (Al2O3, BeO), Semiconductors (Si), Metals (Kovar), etc. The products are widely application in the fields such as radio frequency, microwave, high power diode packaging and optical communication system.

Cu-Mo-Cu heat sinks

Cu/Mo/Cu (CMC) is a sandwich composite including a molybdenum core layer and two copper clad layers. It has tailorable CTE, high thermal conductivity and high strength. All types of Cu/Mo/Cu sheets can be stamped into components.

Inquiry

Cu-Mo70Cu-Cu heat sinks

Cu/Mo70Cu/Cu (CPC) is a sandwich composite like Cu/Mo/Cu including a Mo70-Cu alloy core layer and two copper clad layers. The ratio of the thickness in Cu:Mo-Cu:Cu is 1:4:1. It has different CTE in X and Y direction, higher thermal conductivity than that of W(Mo)-Cu, Cu/Mo/Cu and more cheap. All types of Cu/Mo70Cu/Cu sheets can be stamped into components.

Inquiry

Molybdenum crucible

The finished molybdenum crucible is made by rolled high temperature molybdenum plate with the excellent characters of strength and high temperature resistance. It’s orderly and tidily profiled and well welded in order to ensure the boat having a best lifetime under the condition of high temperature and stress.

Inquiry

Molybdenum electrode material

well corrosion resistance and difficult to stain glass, these high pure molybdenum electrodes have been widely used in many fields such as daily-use glass, optical glass, insulation material and glass fiber, and received good reputes.

TZM

Molybdenum's prime alloy is TZM. This alloy contains 99.2% min. to 99.5% max. of Mo, 0.50% Ti and 0.08% Zr with a trace of C for carbide formations. TZM offers twice the strength of pure molybdenum at temperatures over 1300'C. The recrystallization temperature of TZM is approximately 250'C higher than molybdenum and it offers better weldability.
