C17200 C17500 performance of high-strength beryllium copper - a long lin 
 1. Beryllium copper mold material has excellent electrical conductivity, thermal properties, 2-3 times higher than steel, excellent cooling performance, to shorten the molding cycle time, good heat dissipation, effectively reducing product shrinkage deformation and the degree of control of beer after plastic shrinkage, improved dimensional stability and increase productivity. 

 2 high corrosion resistance, especially for polyethylene (PVC) products of the mold: 

 3 high hardness, wear resistance and toughness, as the mold inserts and accessories used to make copper and aluminum molds for maximum performance and prolong the life of the mold 

 4 excellent polishing performance, high accuracy can be obtained by the mirror surface and shape of complex patterns, 

 5. Anti-stick performance, easily with other metals welding, machining and easily without additional heat treatment. 

 6. Non-magnetic and shock no spark, used in petrochemical, metallurgical and mining production of proof tools. 

 C17200: high-strength beryllium copper main purpose - long-Lin 
 1. Oxygen model: nozzle cavity notch 

 2. Injection mold: mold inserts mold core, cavity, thimble, hot mouth, hot runner system components, die casting, die casting mold, tensile modulus material punch. 


 Introduction to beryllium copper - a long lin 
 Beryllium copper is the mechanical, physical, chemical synthesis of a good performance alloy, after quenching, after quenching, with a high strength, elasticity, abrasion resistance, fatigue resistance and heat resistance, while beryllium copper also has a high conductivity , thermal conductivity, cold and non-magnetic, impact when no spark, easy welding and brazing, in the atmosphere, freshwater and seawater corrosion resistance is excellent. Beryllium copper alloy corrosion in sea water speed: (1.1-1.4) × 10-2mm / year. Corrosion depth: (10.9-13.8) × 10-3mm / year. Corrosion, strength, elongation did not change, so also in the water can be maintained in more than 40 years, is the body of submarine cable repeater construction materials can not be replaced. In sulfuric acid medium: in less than 80% concentration of sulfuric acid (room temperature) on the corrosion depth of 0.0012-0.1175mm, concentrations greater than 80% are slightly accelerated the corrosion.
