黄铜的硬度：黄铜h62拉制棒材(半硬状态)的抗拉强度为:370MPa(直径为5-40mm);伸长率δ10=15%δ5=18%335MPa(直径为>40~80mm);伸长率δ10=20%δ5=24%铸造黄铜屈服强度为120MPa抗拉强度为330MPa伸长率35%加工黄铜--棒材160MPa370MPa49%加工黄铜—管材（软）110MPa360MPa49%加工黄铜—管材（硬）480MPa680MPa3%黄铜是铜与锌的合金.改变黄铜中锌的含量可以得到不同机械性能的黄铜.黄铜中锌的含量越高,其强度也越高,塑性稍代.工业中采用的黄铜含锌量不超过45%,含锌量再高将会产生脆性,使合金性变有效期.在黄铜中加1%锡能显著改善铜的抗海水和海洋大气腐蚀的能力,因此称为”***黄铜”.锡能改性,铅对黄铜硬度强度影响不大.雕刻铜也是铅黄铜的一种.黄铜的牌号：黄铜:H99H95H85H70H68H65H63H62H59………………铝青铜：QAL5QAL7QAL9-2QAL9-4QAL10-3-1.5QAL10-4-4QAL11-6-6QAL9-5-1-1QAL10-5-5…………铍青铜:QBE2QBE1.5QBE1.9-0.1QBE1.7QBE0.6-0.25QBE0.4-1.8QBE0.3-1.5………………锡青铜:QSN1.5-0.2QSN4-0.3QSN4.3QSN4.4-2.5QSN4-4-4QSN6.5-0.1QSN6.5-0.4QSN7-0.2QSN8-0.3…………进口铜料,规格齐全,特殊规格也可订做.无氧铜:C10100C10200CD10300C10400C10500C10700C10800C11000C11020C111000…………铍铜:C17000C17200C17300C17500C17150C18700C19200C19400C19600…………黄铜:C21000C22000C23000C24000C26000C26800C27000C27400C28000…………铅黄铜:C31400C31600C32000C33000C33200C33500C34000C35000C35300C35600C36000C36500C36600C36700C36800C37700C38000C38500…………磷青铜:C50500C51000C51100C52100C5240053200C53400C54400…………铝青铜:C60600C60800C61000C61300C61400C61900C63200C62400C63200C64200C64210…………日顺金属材料谒诚为客户服务，欢迎新老客户来电咨询：0769-82286036/85414926。)
