Due to its high electrical and thermal conductivity, outstanding corrosion resistance, and ease of processing and manufacturing, copper is widely used in modern industry. Next, a brief introduction to the difference between chrome zirconium copper, aluminum oxide copper, purple copper.
1. Chromium-zirconium copper
Chromium zirconium copper is a metal material, chemical formula for CuCrZr, hardness HRB78-83, conductivity of 43ms/m. Chromium zirconium copper has a good electrical conductivity, thermal conductivity, high hardness, wear-resistant anti-explosive, resistance to cracking and softening temperature and other characteristics.
In the welding electrode loss is less, welding speed is fast, the total cost of welding is low, suitable for fusion welding machine as the electrode about the pipe, but the performance of electroplating workpiece is general. Widely used in automobiles, motorcycles, barrels (cans) and other machinery manufacturing industry, welding, conductive nozzle, switch contacts, mold blocks, welding machine auxiliary devices with a variety of materials.
2. Aluminum copper oxide
Copper alumina (also known as diffusion strengthened copper), conductivity ≥ 80% IACS, softening temperature ≥ 900 ℃. It has high strength, high conductivity and high softening temperature.
Comprehensive performance in all aspects of excellence, it is in the welding process, the number of spot welding is high, in the welding of galvanized plate and aluminum plate, electrode life than ordinary chrome zirconium copper to be several times higher, reducing the downtime to repair and grind the electrode time, and improve the efficiency of the automatic welding production line. Alumina copper in the welding of plated metal, the electrode is not easy to deformation, not adhesive, small contact sparks, not blackened, welded joints beautiful, no obvious dents, showing its superb welding performance advantages.
3. Copper
Purple copper is copper monomers, named for its purple-red color. Purple copper is a relatively pure kind of copper, generally can be approximated as pure copper, electrical conductivity, plasticity are better, but the strength, hardness is worse. It has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance.
The electrical and thermal conductivity of copper is second only to silver, widely used in the production of electrical and thermal conductivity equipment. Copper is much more widely used than pure iron, 50% of the copper is electrolytically purified into pure copper for the electrical industry every year. Here the copper, indeed to be very pure, containing copper up to 99.95% or more to line, a very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Mainly used in the production of generators, busbar, cable, switchgear, transformers and other electrical equipment and heat exchangers, pipes, solar heating devices such as flat plate collectors and other thermal equipment.
