查看样本合金摘要数据表（PDF）自1952年以来，合金摘要一直是世界各地使用的金属和合金材料性能数据的主要参考。以图表、图表和表格为特色，这些表格给出了有关成分或特性、物理和机械性能、热处理和可加工性的事实和数字。C68800号铜合金是一种锻造铜基合金（改性黄铜），名义上含有22.7%的锌、3.4%的铝和0.40%的钴。它具有很高的强度和相当好的延展性。通过将回火轧制材料加热到425华氏度（发生有序反应），可以进一步硬化和强化。典型用途包括弹簧、触点、端子和插座。

View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.Copper Alloy No. C68800 is a wrought copper-base alloy (modified brass) containing nominally 22.7% zinc, 3.4% aluminum and 0.40% cobalt. It has high strength and fairly good ductility. It can be hardened and strengthened further by heating temper-rolled material to 425 F where an ordering reaction occurs. Typical uses include springs, contacts, terminals and plug receptacles.
