7005 aluminum sheet belongs to the 7000 series aluminum-zinc-magnesium alloys. It is a medium-to-high strength, heat-treatable aluminum alloy that offers an excellent balance of strength, weldability, and corrosion resistance. Compared with other 7xxx alloys such as 7075, 7005 provides better weldability and stress corrosion resistance, making it especially suitable for welded structures and transportation applications.

Description
Features
- Ultra-high mechanical strength
Suitable for aerospace, transportation, and structural applications requiring maximum strength-to-weight ratio.
- Good corrosion resistance
Performs well in atmospheric and industrial environments; corrosion resistance can be further improved with proper coating or anodizing.
- Good formability and workability
Can be rolled, bent, stamped, and extruded; suitable for medium-to-thin gauge sheets, although forming is more limited compared to 6xxx-series alloys.
- Smooth and uniform surface finish
Ideal for anodizing, painting, or coating for both decorative and functional purposes.
- Good weldability
Compatible with TIG and MIG welding under proper conditions; post-weld heat treatment recommended for optimal strength.
- Lightweight material
Low density helps reduce overall weight while maintaining structural performance.
Typical Applications
- Bicycle frames and high-performance sports equipment.
- Automotive structural components and chassis parts.
- Railway vehicles and transportation structures.
- Industrial welded frames and load-bearing structures.
- Machinery parts and engineering components.
