Product introduction
Chromium-zirconium-copper is a kind of wear-resistant copper with excellent hardness, excellent electrical conductivity and excellent tempering resistance, good uprightness, and the sheet is not easy to bend. It is a very good electrode for aerospace data processing. Hardness>75 (Rockwell) Density 8.95g/cm3 Electrical conductivity>43MS/m Softening temperature>550℃, generally used in the manufacture of welding machine electrodes with operating temperature below 350℃. Motor commutators and other various work at high temperature It is required to have high strength, hardness, electrical conductivity and conductivity parts, and can also be used for brake discs and discs in a bimetallic manner. Its main grades are: CuCrlZr, ASTM C18150 C18200
Chromium zirconium copper has excellent electrical conductivity, thermal conductivity, high hardness, wear resistance, explosion resistance, crack resistance and high softening temperature, less electrode loss during welding, fast welding speed, and low total welding cost, suitable as an electrode for fusion welding machines. It is related to pipe fittings, but it is general for electroplated workpieces.

C17300 Beryllium Cobalt Copper Properties:
Beryllium cobalt copper has excellent processability and high thermal conductivity. In addition, beryllium cobalt copper C17300 also has excellent weldability, corrosion resistance, polishing, wear resistance and anti-adhesion. It can be forged to form parts of various shapes. The strength and wear resistance of beryllium cobalt copper C17300 are better than those of chromium zirconium copper alloy.
C17300 Beryllium Cobalt Copper Use: Medium-strength and high-conductivity components, such as fuse fasteners, springs, connectors, resistance spot welding heads, seam welding rollers, die-casting machine dies, plastic molding dies, etc.
 
The use of C17300 beryllium cobalt copper in mold manufacturing:
Beryllium cobalt copper C17300 is widely used in the manufacture of inserts and 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 of the heat concentrated area, simplifying or eliminating the cooling water channel design. The excellent thermal conductivity of beryllium cobalt copper is about 3 to 4 times better than that of mold steel. This feature can ensure rapid and uniform cooling of plastic products, reduce product deformation, unclear shape details and similar shortcomings, which can be significant in most cases. To shorten the production cycle of products. Therefore, beryllium cobalt copper C17300 can be widely used in molds, mold cores, and inserts that require fast and uniform cooling, especially for high thermal conductivity, corrosion resistance and excellent polishability.
 
1) Blow mold: pinch-off part, ring and handle part inserts. 4) Injection molds: molds, mold cores, inserts at the corners of TV casings, and confluence cavities for nozzles and hot runner systems.
Resistance welding electrode: The mechanical properties of beryllium cobalt copper are higher than those of chromium copper and chromium zirconium copper, but the electrical conductivity and thermal conductivity are lower than those of chromium copper and chromium zirconium copper. These materials are used as welding and seam welding electrodes. Stainless steel, high-temperature alloys, etc., which still maintain the characteristics of high strength at high welding temperatures, because of the need to apply high electrode pressure when welding such materials, the strength of the electrode material is also required to be high. Such materials can be used as electrodes for spot welding of stainless steel and heat-resistant steel, electrode grips, shafts and electrode arms for force-bearing electrodes, as well as electrode hubs and bushings for seam welding of stainless steel and heat-resistant steel, molds, or inlaid electrodes. .
 
Beryllium copper properties: Beryllium copper is a supersaturated solid solution copper-based alloy. It is a non-ferrous alloy with excellent combination of mechanical properties, physical properties, chemical properties and corrosion resistance. Strength limit, elastic limit, yield limit and fatigue limit. At the same time, it has high electrical conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance. Welding electrode materials, die-casting machines, injection molding machine punches, wear-resistant and corrosion-resistant operations, etc., beryllium copper tapes are used in micro-motor brushes, mobile phone batteries, computer connectors, various switch contacts, springs, clips, gaskets, diaphragms , Membrane and other products. It is an indispensable important industrial material in the construction of the national economy.
