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。合金750是一种用于轴承的铝锡镍铜合金。这种材料主要用于永久性模具铸件，由于其快速凝固，其典型特征是具有精细、致密、抗疲劳的结构。 由这种合金的永久性铸模铸件加工而成的实心铝轴承主要用于重型发动机轴承的人工时效-T5回火。在这一领域，750合金在中速和中温条件下的极高单位负荷下提供了令人满意的性能。

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.Alloy 750 is an aluminum-tin-nickel-copper alloy used for bearings. This material is intended for, and has been used principally in the form of permanent mold castings, which by virtue of their rapid solidification are typified by a fine, dense, fatigue resistant structure. Solid aluminum bearings machined from permanent mold castings of this alloy have been used principally in the artificially aged -T5 temper for heavy-duty engine bearings. In this field 750 alloy has provided satisfactory performance under conditions of very high unit loading at medium speeds and temperatures.
