Copper Tungsten Bar Application

Copper tungsten bar is widely used to make Grid siderod, Lead, Support, and Electrode for the Gas discharge lamp, because of the high electrical conductivity and low consumption.
1. Resistance welding electrode
Copper tungsten bar integrates such features of tungsten and copper as high temperature resistance, electrical arc ablation resistance, high proportion, good electrical and heat conductivity, being easy to cut and transpiration cooling. It also owns such advantages of tungsten as high hardness, melting point and adherence resistance. It is often used for projection welding and butt-welding electrode with wear and high temperature resistance.
2. Electric spark electrode
Copper tungsten bar is used for the electrode of mould made from tungsten steel and high-temperature and ultra hard alloy. The common electrode has high consumption and low rate. The high electrical ablation rate, low consumption ratio, precise electrode size and quality processing performance of Copper tungsten can ensure that the precision of the work piece is greatly enhanced.
3. High-voltage discharge tube electrode
When the high-voltage vacuum discharge tube is working, the temperature of contact material will rise to thousands degree centigrade within several tenths seconds. High ablation resistance, high toughness, good electrical and heat conductivity of Copper tungsten provide necessary conditions to stable operation of the discharge tube.
4. Electrical seal material
Copper tungsten bar owns not only the low expansion of tungsten and high heat conductivity of copper. Its expansion index and heat conductivity can also be changed through changing the content of the materials, which provides convenience to the using of the material. We can supply various specifications and the Copper tungsten alloys with different tungsten proportions.

Copper Tungsten Bar Description

Copper tungsten bar is the composite of tungsten and copper, which own the excellent performances of tungsten and copper, such as heat-resistant, ablate-resistant, high-intensity, excellent thermal and electrical conductivity. It is easy to be machined. It is used widely in such industries as engine, electrical power, electron, metallurgy, spaceflight and aviation. Using CIP formation, sintered tungsten skeleton and infiltrating copper (silver) technology, large size and special shape products of tungsten-copper (silver) composites with 6-90 percent of copper are produced, such as electric contacts, electrode, refractory parts, heat sinks and parts of rocket, We can also produce sheet material, tubing, plate and other small products by mould pressing, extrusion pressing and MIM.

Tungsten Copper Block

Tungsten copper is a copper and tungsten alloy that is used to conduct heat and electricity. Tungsten copper consists of 10 to 50 percent of its weight in copper and the remaining portion is made out of tungsten. The lower the copper content, the higher its density and hardness is.
About Tungsten Copper Block
Tungsten copper block is an alloy that is made by pressing tungsten or tungsten carbide, sintering the pressed tungsten at a high temperature, and then infiltrating it with copper. Sintering is a metallurgic process by which a metallic powder is made into a coherent mass by heating without melting. The physical properties of both tungsten and copper make them not mutually soluble, meaning that one cannot be combined with the other, similar to the way oil and water will not mix. The alloy is made by dispersing the particles of one metal into a matrix or crystallized pattern of another. This makes tungsten copper's "micro-structure" or molecular shape that of a metal matrix composite and not of a true alloy.

Copper Tungsten Beads

Our pre-drilled copper tungsten beads are environmentally friendly and offer fly tiers advantages that brass and lead beads do not. Because Tungsten Beads are much denser than lead and brass, nymphs and other wet fly patterns with Tungsten Beads will sink at a faster rate allowing your fly to dig deeper in fast-moving water. Plus, our Copper Tungsten Beads are extremely well-balanced and sport a durable copper finish for extra fish-attracting flash. 20 pack.
