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。AMBRALOY 687是一种铜锌铝砷合金。通过少量但严格控制的砷添加（名义上为0.04%），可有效抑制脱锌。它优于海军金属公司（铜合金编号C44300、C44400和C44500），因为水被污水污染，流速高于正常值，冲击比正常值更严重。典型用途是冷凝器和热交换器管、蒸馏器管和套圈。

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.AMBRALOY 687 is a copper-zinc-aluminum-arsenic alloy. It is effectively inhibited against dezincification by the small but strictly regulated addition of arsenic (nominally 0.04%). It is superior to Admiralty Metal (Copper Alloys No. C44300, C44400 and C44500) where water is contaminated by sewage, where velocities are higher than normal, and where impingement is more severe than normal. Typical uses are condenser and heat-exchanger tubes, distiller tubes and ferrules.
