 [Tungsten copper and silver tungsten Note] 
 Kaifeng, make sure that the products are not lacking, cracks or other abnormalities. 
 The proportion of tungsten copper and silver tungsten steel products. Full attention when used to prevent product falling injured hands or feet. 

 [Note on the shape of the product] 
 Tungsten and copper milling plastic processing, lathe shaping processing, grinding machine, the appearance of the product is not the same as a normal imagination. 

 Tungsten, copper and silver tungsten processing Note] 
 (1) cutting 
 Tungsten copper and silver tungsten alloy in the production of sharp corners of thin-walled may occur due to impact or excessive processing load force lack. Tungsten copper and silver tungsten alloy products during the through-hole drilling 
 Please note that the through-hole is about to feed the load force, to avoid processing lack. 
 Tungsten copper and silver tungsten alloy non-magnetic, East Goes Billiton please can customers confirm that the products have been in the job before fixation. 
 (2) electrical discharge machining, wire EDM 
 Tungsten copper and silver tungsten product discharge wire cutting speed is relatively slow, which is a normal phenomenon. 

 Tungsten, copper and silver tungsten plating Note] 
 Tungsten copper and silver tungsten alloy is a metal powder crystallization of the plating pre-treatment to avoid strong acids, strong alkaline cleaning, so that the surface of metal particles off plating effect. 

 The application of tungsten and copper: tungsten copper is the use of high purity tungsten powder with excellent metallic characteristics and plasticity of high-purity copper powder, high conductivity, etc., isostatic pressing, high temperature sintering, the composite of dissolved copper infiltration process is refined. Broken arc performance, good thermal conductivity, small thermal expansion, high temperature softening, high strength, high density, high hardness. 
 Purposes: 
 Resistance welding electrode: a combination of the advantages of tungsten and copper, high temperature resistance, arc erosion, high strength, heavy, electrical conductivity, thermal conductivity, ease of cutting and sweating Ling was such as features, due to tungsten high hardness, high melting point, anti-adhesion characteristics, often used to a certain wear resistance, high temperature resistance projection welding, butt welding electrodes. 

 (2) high-voltage discharge electrodes: high-voltage vacuum discharge tube at work, contact material within a few tenths of the time, temperature several thousand degrees Celsius, while the anti-ablation properties of tungsten and copper, high toughness, good electrical conductivity, thermal conductivity performance to the discharge tube stable job to provide the necessary conditions. 

 3, aerospace high-performance materials 
 With a high density of tungsten-copper materials, transpiration cooling performance, high temperature and high strength and resistance to erosion ablation performance in the aerospace industry as a missile, rocket nozzle throat, the gas component of the rudder, air rudder, hood and weight. 

 4, vacuum contact materials 
 Contact material must have a very good machining properties and thermal shock resistance, due to the arcing contact and breaking contact material within a few tenths of the time the temperature several thousand degrees Celsius. I produced the W-Cu contact material is widely used because of its excellent physical properties. 
 Advantages: high ablation resistance, high toughness, good electrical conductivity, thermal conductivity performance. Machining performance. 
 Delivery status: copper, steel support links to a good variety of shapes of the W-Cu contact 
 Semi-finished products: processing a variety of infiltration, casting materials; the raw various contacts, welding or brazing, welding or brazing process such as copper or steel support; 
 East Goes Billiton also produces a variety of welding or brazing the contact connections. 

 5, EDM electrodes 
 EDM carbide products, due to the loss of the WC can make the special nature of copper or graphite electrode is quite fast, the EDM of this material, I - East Goes to Rio professional agent imports in the W-Cu, Japan electrode is the most suitable.
