Equivalent grades and alternative selection for 1980 aluminum alloy
Based on available public information, no clearly registered one-to-one foreign equivalent grade has been found for 1980 / V48-4 aluminum alloy. Therefore, it should not be directly treated as an equivalent to any AA, ASTM, or EN grade.
1980 aluminum alloy belongs to the Al-Zn-Mg series. International high-strength alloys such as ASTM B221 7075 and EN AW-7075 under EN 573-3 may be used as references, but they are not complete substitutes for 1980 alloy.
For similar or alternative material selection, the following key points should be compared:
- Focus on checking the main element ranges of Zn, Mg, Mn, Cr, Zr, and Cu, instead of making a simple substitution based only on "high-strength aluminum alloy" or "7xxx series."
- Tensile strength, yield strength, elongation, hardness, and related acceptance values should be compared, especially for load-bearing structures, marine, aviation, or transport engineering applications.
- If 1980 / V48-4 is clearly specified in project drawings or purchasing documents, any substitute material should be approved by the customer, designer, or certification party before use.
