Chromium-zirconium copper is a kind of wear-resistant copper with excellent hardness, excellent conductivity and good tempering resistance, good orthostasis, and the sheet is not easy to bend. It is a good aviation material processing electrode. Hardness "75 (Rockwell) density 8.95g/cm3 conductivity" 43MS/m softening temperature "550 ℃, generally used to make welding machine electrodes with working temperature below 350 ℃. The motor rectifier and other requirements for working at high temperatures have high strength. Hardness. Conductive and conductive parts can also be used in bimetal form for brake discs and discs. Its main brands are: CuCrlZr, ASTM C18150 C18200

chromium zirconium copper has good electrical conductivity, thermal conductivity, high hardness, wear resistance and explosion resistance, crack resistance and high softening temperature, less electrode loss during welding, fast welding speed, and low total welding cost. It is suitable for welding welding The electrode-related pipe fittings of the machine, but the performance of the electroplated workpiece is general.

This product is widely used in various materials for welding, conductive nozzles, switch contacts, mold blocks, welding machine auxiliary devices in machinery manufacturing industries such as automobiles, motorcycles, barrels (cans), etc.

C17300 beryllium cobalt copper properties:

beryllium cobalt copper has good processability and high thermal conductivity. In addition, beryllium cobalt copper C17300 also has excellent weldability, corrosion resistance, polishing, wear resistance and adhesion resistance. The strength and wear resistance of beryllium cobalt copper C17300 is better than that of chromium zirconium copper alloy for parts of various shapes.

C17300 beryllium cobalt copper application: medium high strength conductive parts, such as fuse fasteners, springs, connectors, resistance spot welding heads, seam welding rollers, die casting machine heads, plastic molding dies, etc.

Application of C17300 Beryllium Cobalt Copper in Mold Manufacturing Industry:

beryllium cobalt copper C17300 is widely used to manufacture inserts and mold cores in injection molds or steel molds. When used as an insert in a plastic mold, C17300 beryllium cobalt copper can effectively reduce the temperature in the heat concentration area and simplify or omit the cooling water channel design. The excellent thermal conductivity of beryllium cobalt copper is about 3~4 times superior to that of mold steel. This characteristic can ensure the rapid and uniform cooling of plastic products, reduce the deformation of products, unclear shape details and similar defects, and can significantly shorten the production cycle of products in most cases. Therefore, beryllium cobalt copper C17300 can be widely used in molds, mold cores and inserts that require rapid and uniform cooling, especially the requirements of high thermal conductivity, corrosion resistance and good polishing.

1) Blow molding: inserts at the clamping part, the stiffening ring and the handle part. 4) Injection mold: mold, mold core, insert in the corner of TV shell, nozzle and junction cavity of hot runner system.

Resistance welding electrode: Beryllium cobalt copper has higher mechanical properties than chromium copper materials and chromium zirconium copper materials, but the conductivity and thermal conductivity are lower than chromium copper and chromium zirconium copper. This type of material is used as welding and seam welding When electrodes, it is used to weld stainless steel, high-temperature alloys, etc. that still maintain high-strength characteristics at high temperatures, because higher electrode pressure needs to be applied when welding such materials, and the strength of the electrode. This kind of material can be used as electrode for spot welding stainless steel and heat-resistant steel, electrode grip, shaft and electrode arm, electrode axle and bushing for seam welding stainless steel and heat-resistant steel, mold or inlaid electrode.

Beryllium copper characteristics: Beryllium copper is a supersaturated solid solution copper-based alloy. It is a non-ferrous alloy with good mechanical properties, physical properties, chemical properties and corrosion resistance. After solid solution and aging treatment,

it has high strength limit, elastic limit, yield limit and fatigue limit equivalent to special steel. At the same time, it has high conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance,

it is widely used in the manufacture of various mold inserts, replacing steel to make molds with high precision and complex shapes, welding electrode material die casting machines, injection molding machine punches, wear-resistant and corrosion-resistant work, etc., beryllium copper tape is used in micromotor brushes, mobile phone batteries,

computer connectors, various switch contacts, springs, clips, washers, diaphragms, membranes and other products. It is an indispensable and important industrial material in the construction of the national economy.
