Tungsten Copper W75Cu25 Special Shape Alloy for Heating Sink

WCu alloy rods size: diameter(3.0-200mm)*L<500mm
WCu tungsten copper alloy application and performance:
1.  Arcing contacts and vaccum contacts in high and medium voltage breakers or vaccum interruptors;
2.  Electrodes in electric spark erosion cutting machines;
3.  Electrodes for resistance welding;used where the combination of high heat resistance, high electrical
4. Some of the applications are in electric resistance welding, as electrical contacts, and as heat sinks.
5. As contact material the alloy is resistant to erosion by electric arc. WCu alloys are also used in electrodes for electrical discharge machining and electrochemical machining.
 
 Advantages of Copper Tungsten Plates:
1. Better heat resistant; 
2. Better ablate-resistant; 
3. High intensity
4. High density; 
5. Excellent thermal and electrical conductivity; 
6. Easy to be machined. 

Be relative to tungsten copper alloy,we also supply tungsten nickel copper/Iron alloy
High Quality Tungsten High Heavy Alloy ASTM B777-07 rods/sheet/tubes

Material:W90-97NiFe(Magnetic)&W90-97NiCu(Nonmagnetic)
Density:16.8-18.8g/cm3

• High density (up to 65% denser than Lead). 
• Denser materials exist (, pure Tungsten, Gold, platinum group metals) but their use is restricted by availability, workability and cost. 
• Providing mass where volume space is limited. 
• Concentrated weight essential where accuracy is required in placement of mass. 
• Placement of weight in situations where airflow has a significant impact.
