  • QBe2.0

    QBe2.0 Beryllium Bronze contains a small amount of nickel and is a high-performance copper alloy with good mechanical, physical, and chemical comprehensive properties; it has high strength, hardness, elasticity, and wear resistance after solid solution and age hardening (quenching and tempering). Resistance, corrosion resistance, heat resistance, explosion resistance, yield and fatigue limit; at the same time, it also has high electrical conductivity, thermal conductivity and cold resistance, non-magnetic, no spark when hit, easy to weld and braze, easy to process , Excellent cooling effect, excellent corrosion resistance in the atmosphere, fresh water and sea water.

    Used in high-precision electronic, plastic and optical molds where the water can not pass as inserts for heat dissipation, mold cores, punches, hot runner cooling systems, communication preparation equipment, electronic and electrical equipment, instruments, aerospace, automotive manufacturing, and processed parts Raw materials.
