C1720 bronze C1720 Beryllium copper properties and application of beryllium copper alloy set excellent mechanical properties, physical properties and chemical properties after heat treatment (solution treatment and aging treatment), with special steel with very high ultimate strength, elastic limit in one , yield strength and fatigue limit, but also have high electrical conductivity, thermal conductivity, high hardness, corrosion resistance, abrasion resistance, good casting properties, non-magnetic and shock characteristics of spark, in the mold manufacturing, mechanical, electronic and other industries widely used. C1720 beryllium copper mechanics, physical and chemical properties of an alloy after quenching after quenching, having high strength, elasticity, wear resistance, fatigue resistance and heat resistance, also has a high copper beryllium electrical conductivity, thermal resistance, cold resistance and non-magnetic, impact and non-sparking, easy welding and brazing, excellent corrosion resistance in the atmosphere, fresh water and sea water. Corrosion, strength, elongation rate did not change, it is still in the water can be maintained for more than 40 years, submarine cable repeater structure irreplaceable material. Beryllium copper beryllium-copper alloy as the main alloying elements, also known as bronze. C1720 beryllium copper grades of chemical composition Al Be Si Ni, Fe Pb Cu impurities total C1720 0.15 1.8-2.1 0.15 0.2-0.5 0.15 0.005 margin of 0.5 density thermal conductivity hardness softening temperature of of 8.36 g/cm3 90-120 w / mk 36-42 HRC 870-980 C1720 main features sufficient hardness and strength, good thermal properties, long service life and high rate of heat penetration, high corrosion resistance C1720 beryllium copper main purpose it is the best performance of the senior elastic material copper alloy , has a high strength, elasticity, hardness, fatigue strength, elastic hysteresis, corrosion, wear-resistant, cold-resistant, highly conductive, non-magnetic, shock does not produce sparks and a series of excellent physical, chemical and mechanical properties. No blisters, porosity, hardness equalizer, dense, high strength, good thermal conductivity, good electrical conductivity, corrosion resistance, excellent wear resistance, good workability, high pressure under the conditions of stable performance, non-magnetic, excellent polishing performance, good anti-adhesion properties. C1720 use of beryllium copper injection molds and high-pressure blow molds, mold inserts, rapid cooling, aluminum mold inserts, increased strength, abrasion resistance and shorten the molding cycle mold, hot runner nozzle, electrode, and punch material is not magnetic non-magnetic tools, high thermal conductivity bearings, can produce high surface accuracy of the mirror. Blowing mold: air nozzle, notches, the cavity injection mold: mold core, cavity, thimble, hot water port, hot runner system parts, mold inserts, casting mold, die casting mold, tensile modulus material, the punch Be :1.90-2 .15 C1720 beryllium beryllium bronze [1] cobalt Co :0.35-0 .65 Ni Ni :0.20-0 .25 copper Cu: the margin Si Si: <0.15 iron Fe: <0.15 Aluminum Al: <0.15 standard for comparison: AISI C17200 main Performance indicators: Tensile strength (Mpa): 1105 Specific Gravity (g/cm3): 8.3 yield strength (0.2%) Mpa: 1035 softening temperature (° C): 930 Elongation (%): 1 elastic modulus (GPa): 128 Hardness (HRC) :38-44 thermal conductivity (W/m.k20 ° C): 105 Conductivity (IACS): 18 main products are as follows: A. electronic stamping copper-nickel alloy with JIS-C7521, C7541, C7701, C75200 , C77000, C75700, C73500 phosphor bronze with JIS-C5210, C5191, C5212, C5111, C5102, CuZn4, CuZn5, CuZn6, beryllium copper strip JIS CuZn8 red copper (T2, TP2, C1220, TU2, C1100, C1020, C1201) -C1730, C1720, C1715 brass band JIS-C2680, C2720, C2600, C2700, C2801 lead frame strips KFC, C194, C1921 B. mold electrode copper / welding electrode with copper: chromium (zirconium) copper (JMC -2 \ C18200 \ C18150) beryllium copper JMC -4 \ C17200 \ C17500 tungsten copper (JMC -7) the beryllium nickel-copper beryllium, cobalt and copper C. machining of copper: cutting brass, lead-free environmental protection brass, phosphor bronze wire rod RF coaxial connector beryllium copper JIS-C1730, C17300 The company's complete product specifications, and the price is reasonable, but also according to the needs of different users, non-standard build. welcome new and old customers call to discuss ordering online!
