常用铍铜中铍的质量分数为1.7-2.5%,铍青铜经过淬火和时效可以具有极高的强度和硬度,远超过其他所有的铜合金,甚至可以和高强度钢蓖美.它的弹性极限疲劳极限耐磨性耐腐蚀性也都很好,是各种性能结合得很好的一种合金;还具有很好的物理化学性能.就是价格太高!常用牌号:QBe2QBe1.5QBe1.7等.德国OF-CuSE-CuE-Cu58SF-CuSW-CuCuZn5CuZn10CuZn15CuZn20CuZn30CuZn33CuZn36CuZn37CuZn36Pb1.5CuZn40CuZn31Si1CuZn20Al2CuSn4CuSn5…………欧洲Cu-OFECu-HCPCu-PHCCu-ETPCu-DHPCu-DLPCuZn35Pb1CuZn35Pb2CuZn20Al2AsCuZn28Sn1AsCW009ACW021ACW020ACW506LCW507LCW508LCW600N………美国C11000C12200C12000C21000C22000C23000C24000C26000C26800C27000C27200C34000C34200C28000C35000C36000C37700C38500…………日本C1011C1100C1220C1201C2100C2200C2300C2400C2600C2680C2700C2720C3501C3712C3601………铜合金C17000C17200C17300C17510C17500C17410275CC10100C10200C10300C10400C10500C10700C10800C11000C12000C12200C12500C14500C14510…………铝黄铜:HAl77-2C68700687CZ110CuZn22Al22.0460C6870HAi66-6-3-2670C6872HAi60-1-1C67000678CuZn37Al………..)
