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. 
Machinability 
  • Possible, either to press components to shape, or to cut and shape material prior to sintering. 
  • Reducing the amount of final machining necessary to produce the finished component. 
  • Can be machined conventionally and without much difficulty. 
Production Method 
  • Blending of tungsten powder with other metal powders and a bonding agent, cooling and sieving. 
  • Pressing the blended powder to the required shape (allowing for shrinkage during the final processing), and shaping the green part component. 
  • Pre-sintering the pressed components to remove the bonding agent. 
  • Final sintering in the hydrogen fed furnace to fuse the powder particles together. 
  • Supplied in bar, square, round and rectangle sizes are available in rough oversize, or turned or ground to exact requirements. Components can also be produced to customer drawings. 
Thermal Properties 
  • High softening temperature. 
  • Low thermal conductivity and low coefficient of expansion gives the material a high resistance to thermal fatigue. 
  • Excellent soldering erosion resistance to molten aluminium. 
  • Strong at high temperatures with high thermal stability.

Fresh Apple

Apple is a common fruit with smooth skin that is usually red, yellow, or green in color. It has a refreshing taste and sweet flavor, and is rich in vitamin C and fiber, which are beneficial for health. Apples can be eaten raw or used to make various delicious juices, jams, and desserts. When choosing fresh apples, look for fruits with no obvious flaws, smooth and shiny skin. For storage, it is best to keep them in a cool, ventilated place away from direct sunlight and high temperatures. Fresh apples are a healthy and delicious fruit that is suitable as part of a daily diet.
