Implementation Standards and Industry Norms
Aluminum plate manufacturing typically adheres to standards like ASTM B209, EN 485-2, EN 573-3, and specific industry certification depending on application-focused requirements (AIR6378 for aerospace, DNV standards for marine plates).
Alloy Tempering and Processing Conditions
For these aluminum plates, treatment influences mechanical properties profoundly. Common tempers include:
- T6 temper: Solution heat treated and artificially aged, provides high tensile strengths (7075-T6, 6061-T6, 6082-T6).
- H116 or H321: Stress relieved or slightly strain-hardened tempers, widely used for marine grades such as 5083.
- T5 temper: Cooled from an elevated temperature forging or shaping, aged artificially (common in 6063 for perfect surface finish and moderate mechanical strength).
Heat treatment ensures the right balance between strength, ductility, hardness, and corrosion resistance, helping aluminum plates meet demanding field requirements.
