銅合金性能介紹及使用
beryllium copper beryllium bronze high king of the "elastic" beryllium copper for the domestic most the high grade mould beryllium copper, containing beryllium by around 2%, with high strength, high hardness, high conductivity, high elasticity, wear resistance, fatigue resistance, corrosion resistance and low elastic hysteresis, etc, is mainly used for temperature control, phone battery, computers, auto parts, micro-motor, brush needle, senior bearings, eyeglasses, contact parts, gear, punch and all kinds of no spark switch, all kinds of welding electrodes and precision casting mold and so on.
鈹銅#鈹青銅“彈性*”高鈹銅為的模具鈹銅，一般含鈹2%左右，具有高強(qiáng)度、高硬度、高導(dǎo)電性、高彈性、耐磨、耐疲勞、抗腐蝕性及彈性滯后小等特點(diǎn)，主要用于溫度控制器、手機(jī)電池、電腦、汽車零配件、微電機(jī)、電刷針、軸承、眼鏡、接觸件、齒輪、 沖頭、各類無火花開關(guān)、各類焊接用電極及精密鑄造模具等。
高性能鈹青銅主要圍繞有色金屬低壓、重力鑄造模具使用的各種工況，通過深入研究鈹青銅模具材料失效原因、成份和耐金屬液侵蝕性內(nèi)在關(guān)系，開發(fā)了高導(dǎo)電（熱）性、高強(qiáng)度、耐磨性、耐高溫性、高韌性、耐金屬液侵蝕相結(jié)合的高性能鈹青銅模具材料，解決了國內(nèi)有色金屬低壓、重力鑄造模具易裂、易磨損等難題，顯著提高了模具壽命和鑄件強(qiáng)度；克服了金屬液渣粘附和侵蝕模具；改善了鑄件表面質(zhì)量；降低了生產(chǎn)成本；使模具壽命接近進(jìn)口水平。
