Chromium-zirconium copper is a wear-resistant copper with excellent hardness, superior conductivity, and good temper resistance. It has good straightness, and thin sheets are not easily bent, 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 making electrode for electric welders with operating temperatures below 350°C, motor rectifier plates, and various parts that require high strength, hardness, conductivity, and ductility for high-temperature operation. 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, heat conductivity, high hardness, wear resistance, explosion resistance, and high softening temperature. It has minimal electrode loss during welding, enabling quick welding speeds and low overall welding costs. It is suitable for use as electrode-related fittings in fusion welding machines, but it performs averagely for electroplated workpieces.
Application: This product is widely used in the welding, conductive nozzles, switch contacts, mold blocks, and auxiliary equipment for welding machines in the mechanical manufacturing industries such as automotive, motorcycle, and barrel manufacturing.
C17300 Beryllium Cobalt Copper Properties:
Beryllium cobalt copper has good machinability, high thermal conductivity, and also exhibits excellent weldability, corrosion resistance, polishing, wear resistance, and anti-sticking properties. It can be forged into various shaped parts, with Beryllium cobalt copper C17300 offering superior strength and wear resistance compared to chrome zirconium copper alloys.
C17300 Beryllium Copper Applications: Medium strength, high conductivity components such as fuse fixings, springs, connectors, resistance spot welding tips, seam welding rolls, die casting molds, plastic molding dies, etc.
Application of C17300 Beryllium Copper in Die Casting Industry:
Beryllium cobalt copper C17300 is widely used in the manufacture of inserts and cores in injection molds or steel molds. When used as inserts in plastic molds, C17300 beryllium cobalt copper can effectively lower the temperature in hot spots, simplifying or eliminating cooling water channel design. Its excellent thermal conductivity, about 3-4 times better than that of mold steel, ensures rapid and even cooling of plastic products, reducing deformation, unclear exterior details, and similar defects. In most cases, this can significantly shorten the production cycle. Therefore, C17300 beryllium cobalt copper is extensively applied to molds, cores, and inserts requiring rapid and even cooling, particularly those with high thermal conductivity, corrosion resistance, and good polishing properties.
1) Blown molding mold: Inserts for the cutting section, reinforcing rings, and handle area. 4) Injection mold: Molds, cores, inserts for the corners of TV shells, nozzles, and the manifold of the hot runner system.
Resistance Welding Electrodes: These materials, made of beryllium-cobalt-copper, have superior mechanical properties compared to chrome copper and chrome zirconium copper, yet lower conductivity and thermal conductivity. They are used as welding and seam welding electrodes for materials like stainless steel and high-temperature alloys that maintain high strength at high temperatures, as higher electrode pressure is required for welding such materials. These materials are suitable for spot welding electrodes of stainless and heat-resistant steels, force electrodes, electrode holders, shafts, and electrode arms. They can also be formed into electrodes for seam welding of stainless and heat-resistant steels, sleeve inserts, molds, or embedded electrodes.
Beryllium copper characteristics: Beryllium copper is an oversaturated solid solution copper-based alloy, a non-ferrous metal that combines excellent mechanical, physical, chemical, and corrosion-resistant properties. After undergoing solid solution and aging treatments,
Equivalent to special steel in tensile strength, elastic limit, yield strength, and fatigue limit. Additionally, it boasts high conductivity, thermal conductivity, hardness, wear resistance, creep resistance, and corrosion resistance.
Widely used in manufacturing various mold inserts, replacing steel for high-precision, complex-shaped molds, welding electrode materials for die casting machines, injection mold inserts, and wear-resistant and corrosion-resistant workpieces. Beryllium copper strips are applied in micro-motor brushes, mobile phone batteries, computer connectors, various switch contacts, springs, clamps, washers, diaphragms, and laminates, among other products. It is an indispensable important industrial material in the construction of the national economy.
