ISO 5755:2012规定了用于轴承和结构零件的烧结金属材料的化学成分和机械物理性能要求。 在选择粉末冶金（PM）材料时，应考虑其性能不仅取决于化学成分和密度，还取决于生产方法。在特定应用中提供满意服务的烧结材料的性能可能不一定与其他可能使用的锻造或铸造材料的性能相同。因此，建议与潜在供应商联系。

ISO 5755:2012 specifies the requirements for the chemical composition and the mechanical and physical properties of sintered metal materials used for bearings and structural parts. When selecting powder metallurgical (PM) materials, it should be taken into account that the properties depend not only on the chemical composition and density, but also on the production methods. The properties of sintered materials giving satisfactory service in particular applications may not necessarily be the same as those of wrought or cast materials that might otherwise be used. Therefore, liaison with prospective suppliers is recommended.
