FAQ for 7075 Aluminum Alloy
What is the main difference between 7075 and 6061 aluminum?
7075 is much stronger, with higher tensile/yield strength, but less corrosion resistance in untreated form; 6061 is more versatile and easier to weld.
Which tempers are commonly used for aerospace applications?
T6 and T73 are preferred for aerospace and defense due to high strength and stress-corrosion resistance.
Can 7075 be welded directly?
Direct welding reduces strength; recommended to use friction stir welding or specialized TIG/MIG with post-weld heat treatment.
Is 7075 suitable for marine environments?
Yes, after anodizing or protective coatings, it resists seawater corrosion.
What standards does 7075 comply with?
EN 485, EN 573, ASTM B209, ASTM B211, ASTM B928, GB/T 3190. Certificates: EN10204 3.1, SGS, BV.
Can 7075 be anodized or coated?
Yes. Clear anodizing, color anodizing, powder coating, and polishing are all compatible.
Typical lead time for 7075 aluminum?
Stock products: 5–10 days, custom size or temper: 15–25 days.
Can 7075 aluminum be supplied as rod, tube, or coil?
Yes. Rods Ø10–300 mm, sheets/coils 1–10 mm thickness, tubes custom OD/ID are available.
What industries primarily use 7075?
Aerospace, defense, automotive racing, precision tooling, marine high-strength structures.
Can 7075 replace steel in high-strength structural components?
Yes. It offers ~70% weight reduction with comparable strength, ideal for lightweight high-performance designs.
