Product Brief Introduction

W-Cu heat sink material is a composite of tungsten and copper, with both tungsten low expansion characteristics, but also has copper of high thermal conductivity properties, and the tungsten and copper in the thermal expansion coefficient and thermal conductivity can be adjusted with the W-Cu composition, also the composite can be machined to various shape, these features make the application of this composite with great convenience. The thermal expansion can be adjusted to match with the following material:
Ceramic materials: , (A-90,A-95,A-99), BeO (B-95, B-99), AIN, etc;
Semiconductor materials: Si, GaAs, SiGe, SiC, GaP;
Metal Material: Kovar alloy(4J29), 42 alloy;


Application

(1).Copper tungsten alloy is used when a product or part needs to have a high heat resistance, low thermal expansion and high electrical or thermal conductivity. 

(2)/Tungsten copper alloy is used to make engines and electrical devices. It is also used in the fields of aviation and spaceflight. Electrodes, refractory parts, heat sinks, rocket parts and electrical contacts are all made out of WCu alloy. 

(3).The alloy is also made into sheet metal, tubing and plate metal. WCu alloy is used to make contacts for both high and low voltage electrical devices, and for high speed steel devices and switches. 

(4).The Spark Erosion (EDM) process calls for copper tungsten. Usually this process is used with graphite, but tungsten has a high melting point. This allows the CuW electrodes to have a longer service life than the graphite electrodes. This is crucial when the electrodes have been processed with complex machining. Since the electrodes are susceptible to wear the electrodes provide more geometrical accuracy than the other electrodes. These properties also let the rods and tubes manufactured for spark erosion be made smaller in diameter and have a longer length since the material is less likely to chip and warp.

FAQ

Q: What information should I let you know if i want to get a quotation?

A: The required material dimension (Thickness*Width*Length,diameter*length; if possible, please kindly supply us drawings).
The required more information, such as Surface Condition, Tolerance Request, The Quantity, and other mechanical and technical details.
     
If it is possible, please also provide the application of products, we will recommend the most suitable products with details for confirmation.
 
Q: How do you gurantee the quality of the products?

A: Each step of production and finished products will be carried out inspection by QC department before storing in the warehouse. NG goods are not allowed in the completed goods warehouse.
 
Q: Can you guarantee the prompt delivery?

A: Yes, when we get your inquiries, not only we will evaluate the more competitive price, but also we can get the most reasonable delivery time. So the prompt delivery can be guaranteed.
 
Q: What is the shipping cost?

A: The shipping cost is determined by the destination port, weight, packing size, total CBM of the products, we will try best to get the most reasonable shipping cost from the forwarders or express couriers to help you save more money.

Q:What is the transportation way?
A:If the Gross Weight ≤45kg, it's better by express such as TNT, DHL, FedEx,, etc. 
If the Gross Weight between 45kg to 100kg, by express or by air to your nearest airport can be both considered.
If the Gross Weight ≥ 100kg ,you can choose by Air or Sea to the nearest port.
