Beryllium copper is a mechanical, physical, chemical properties of a good alloy, after quenching and tempering, with high strength, elasticity, abrasion resistance, fatigue resistance and heat resistance, at the same time, beryllium copper also has a very high electrical conductivity, thermal conductivity, cold resistance and non-magnetic, non-sparking impact, easy to weld and braze, in the atmosphere, fresh water and seawater in the corrosion resistance is very good. Beryllium copper alloy in seawater corrosion rate: (1.1-1.4) × 10-2mm/year.
Chemical composition/% Aluminum Al: 0.1-0.25, Magnesium Mg: 0.1-0.25, Chromium Cr: 0.65, Zirconium Zr: 0.65, Iron Fe: 0.05, Silicon Si: 0.05, Phosphorus P: 0.01, Total impurities: 0.2.
Corrosion depth: (10.9-13.8) × 10-3mm/year. After corrosion, strength, elongation are no change, so in the water can be maintained for more than 40 years, is an irreplaceable material for submarine cable repeater structure. In sulfuric acid medium: less than 80% concentration of sulfuric acid (room temperature) annual corrosion depth of 0.0012-0.1175mm, concentration greater than 80% of the corrosion is slightly accelerated.
C17300 beryllium cobalt copper performance: beryllium cobalt copper processing is good, high thermal conductivity, in addition to beryllium cobalt copper C17300 also has excellent weldability, corrosion resistance, polished, abrasion resistance, anti-adhesion.

Beryllium copper is a supersaturated solid solution copper-based alloy, is the mechanical properties, physical properties, chemical properties and corrosion resistance of a good combination of non-ferrous alloys, after solid solution and aging treatment, with special steel equivalent to the high strength limit, elasticity limit, yield limit and fatigue limit, at the same time have a high electrical conductivity, thermal conductivity, high hardness and abrasion resistance, high creep resistance and corrosion resistance, is widely used in the manufacture of various types of Mold inlays, alternative steel production of high precision, complex shapes of the mold, welding electrode materials, die-casting machines, injection molding machine punches, wear-resistant and corrosion-resistant work. Beryllium copper tape is used in micro-motor brushes, cell phones, batteries, products, is an important industrial material indispensable to the construction of the national economy.
Mold manufacturing C17300 beryllium cobalt copper applications: beryllium cobalt copper C17300 is widely used in the manufacture of injection molds or steel mold inserts and cores. When used as inserts in plastic molds, C17300 beryllium cobalt copper can effectively reduce the temperature of the heat concentration area, simplify or eliminate the design of the cooling waterway. Beryllium cobalt copper's excellent thermal conductivity is about 3~4 times better than mold steel. This characteristic ensures rapid and uniform cooling of plastic products, reduces product deformation, unclear shape details and similar defects, and significantly shortens the production cycle of products in most cases. Therefore, Beryllium Cobalt Copper C17300 can be widely used in molds, cores, inserts that require fast and uniform cooling, especially high thermal conductivity, corrosion resistance and good polishability requirements.
