Chromium-zirconium copper is a wear-resistant copper with excellent hardness, superior conductivity, and good temper resistance. It has good uprightness and is not easily bent into thin sheets, making it an excellent material for aerospace electrode processing. Hardness > 75 (Rockwell), Density 8.95 g/cm³, Conductivity > 43 MS/m, Softening Temperature > 550°C. Generally used for electrodes of electric welders operating at temperatures below 350°C, motor rectifier plates, and various parts that require high strength, hardness, conductivity, and ductility under high temperatures. It can also be used in the form of bimetal for brake discs and plates. Its main grades include: CuCr1Zr, ASTM C18150, C18200.
Chromium-zirconium copper boasts excellent conductivity, thermal conductivity, high hardness, wear resistance, explosion resistance, high resistance to cracking, and a high softening temperature. It experiences minimal electrode wear during welding, allowing for fast welding speeds and low overall welding costs, making it suitable for electrode-related components in fusion welding machines. However, it performs averagely in electroplated workpieces.
Application: This product is widely used in the welding, conductive nozzles, switch contacts, mold blocks, and auxiliary devices for welding machines in various mechanical manufacturing industries such as automotive, motorcycle, and drum-making.
C17300 Beryllium Cobalt Copper Properties:
Beryllium copper offers good machinability, high thermal conductivity, and also boasts excellent welding, corrosion resistance, polishing, wear resistance, and anti-sticking properties. It can be forged into various shapes of parts. The strength and wear resistance of Beryllium copper C17300 are superior to those of chrome zirconium copper alloys in terms of physical properties.
C17300 Beryllium Copper Applications: Medium strength, high conductivity components such as fuse clips, springs, connectors, resistance spot welding tips, seam welding rolls, die casting molds, plastic molding dies, etc.
Application of C17300 beryllium-cobalt-copper in the mold manufacturing industry:
Beryllium copper C17300 is widely used in the manufacturing of inserts and cores for injection molds or steel molds. When used as inserts in plastic molds, C17300 beryllium copper can effectively reduce the temperature in hot spots, simplifying or eliminating the need for cooling water channels. Its excellent thermal conductivity is about 3 to 4 times better than that of mold steel, ensuring rapid and even cooling of plastic products, reducing deformation, unclear外形 details, and similar defects, and can significantly shorten the production cycle in most cases. Therefore, C17300 beryllium copper is extensively applied in molds, cores, and inserts requiring rapid and uniform cooling, particularly for high thermal conductivity, corrosion resistance, and good polishing properties.
1) Blow molding mold: Fittings for the cutting section, reinforcing rings, and handle area. 4) Injection mold: Mold, mold core, inserts for the TV cabinet corners, nozzle, and manifold of the hot runner system.
Resistance Welding Electrodes: Beryllium cobalt copper exhibits higher mechanical properties than chrome copper and chrome zirconium copper materials, but lower electrical and thermal conductivity. This type of material is used as welding and seam welding electrodes for stainless steel and high-temperature alloys that maintain high strength at high temperatures, as higher electrode pressure is required when welding such materials. This is due to the need for higher strength in the electrode material. Such materials can be used as electrodes for spot welding stainless steel and heat-resistant steel, force electrodes, electrode handles, shafts, and electrode arms. They can also be made into seam welding electrode wheels and bushes, molds, or embedded electrodes.
Beryllium copper characteristics: Beryllium copper is an over-saturated solid solution copper-based alloy, a non-ferrous alloy with a good combination of mechanical, physical, chemical, and corrosion-resistant properties. After solution treatment and aging.
High strength, elastic, yield, and fatigue limits comparable to special steel, along with high conductivity, thermal conductivity, hardness, wear resistance, creep resistance, and corrosion resistance.
Widely used in manufacturing various mold inserts, replacing steel in making high-precision, complex-shaped molds, welding electrode materials for die casting machines, injection molding punch heads, wear and corrosion-resistant workpieces, and more. Beryllium copper strips are applied in micro-motor brushes, mobile phone batteries, computer connectors, various switch contact points, springs, clamps, washers, diaphragms, and other laminated products. It is an indispensable important industrial material in the construction of the national economy.
