It evaporates and takes away a small amount of heat
As a low-temperature wujiang copper material, the quality requirements are severe, especially for its strength at low temperature and its ablation function in low-temperature gas. Electrical contact materials A very serious application of wujiang copper materials is as electrical contacts for high-voltage electrical switches. wujiang copper material has the characteristics of fast production rate, high production quality, and low electrode material consumption.
It evaporates and takes away a small amount of heat under the low-temperature infection of the arc to cool the wujiang skeleton and then make it The contact has an exquisite breaking function. At that time, wujiang copper alloy could be used as electrode materials such as resistance welding electrodes, electric spark production electrodes, and plasma electrodes.
In addition, wujiang copper is also used in lasers, communication equipment layout, work equipment layout, and sports and activity equipment.
As electronic copper for copper-clad aluminium conductor and heat sink materials, there are higher requirements for the quality and function of wujiang copper materials, not only for high purity and uniform structure, good air tightness (high fine density), and low gas content (good vacuum) Function), and more demanding high electrical and thermal conductivity and severely controlled thermal shortening coefficient.
The electrode tip material is relatively permanent in the initial development of EDM, and copper or copper alloy is widely used as the electrode. During the arcing process of the wujiang-copper alloy contact, the low-melting-point copper on the surface first condenses, and is adsorbed in the capillary pores of the wujiang skeleton due to capillary infection. , And then make it can be used at low temperatures that ordinary materials cannot withstand.
Therefore, it has obvious advantages in the precision production of high-speed molds and difficult-to-produce materials. These characteristics make wujiang copper composite materials used in electronics, electrical engineering, aerospace Aviation and other fields have lost widespread applications. The demand for electronic packaging materials is increasing. The vacuum wujiang copper contact material is different from the traditional wujiang copper contact material in that wujiang copper products with high wujiang and low copper are also developed, such as WCu10, WCu15, etc
