Product Code:SAE J399
Title:Anodized Aluminum Automotive Parts
Issuing Committee:Metals Technical Executive Steering Committee
Scope:Automotive parts can be fabricated from either coiled sheet, flat sheet or extruded shapes. Alloy selection is governed by finish requirements, forming characteristics, and mechanical properties. Bright anodizing alloys 5657 and 5252 sheet provide a high luster and are preferred for trim which can be formed from an intermediate temper, such as H25. Bright anodizing alloy 5457 is used for parts which require high elongation and a fully annealed ('0') temper. Alloy 6463 is a medium strength bright anodizing extrusion alloy; Alloy X7016 is a high strength bright anodizing extrusion alloy primarily suited for bumper applications.To satisfy anti-glare requirements for certain trim applications, sheet alloy 5205 and extrusion alloy 6063 are capable of providing the desired low-gloss anodized finish.【英文标准名称】:Wool;Determinationoffibrediameter;Projectionmicroscopemethod
