7075 / EN AW-7075 Ultra-High Strength Alloy Plate



Contact Us

7075 / EN AW-7075 (AlZn5.5MgCu) is heat-treatable 7xxx series ultra-high strength Al-Zn-Mg-Cu alloy. It ranks among the strongest commercial aluminium alloys, tensile strength close to mild steel while only 1/3 density of steel. High strength is achieved by solution treatment and artificial aging. Widely used for aerospace, high precision moulds, heavy-duty jigs & fixtures, automation structural parts and racing components.

Not suitable for conventional welding; corrosion resistance inferior to 5xxx alloys, protective coating required for marine environment.

7075 is heat-treatable aluminum alloy. Temper controls strength, residual stress, dimensional stability and SCC resistance. T651 is preferred for export thick plate; T7351 for improved stress corrosion resistance; O temper only for forming, limited stock.

Delivery status

Common supply status (Temper)	O	Fully annealed soft temper, low strength, fair ductility	T651	Solution treated, stretched for stress relief + artificial aging, low residual stress
Common supply status (Temper)	T6	Solution treated + peak artificial aging, maximum strength, residual stress exists	T73 / T7351	Over-aged treatment, slightly lower strength, greatly improved SCC resistance

Advantages

Ultra high specific strength, tensile strength 540~590MPa for T6/T651

Excellent machinability, ideal for CNC precision machining & mould fabrication

Stable mechanical property under low temperature

High hardness & compression resistance for heavy load fixtures

Limitations: Poor fusion welding performance; risk of stress corrosion cracking; ordinary corrosion resistance, coating/anodizing required; high material cost; large springback during bending, not fit for complex sheet forming.

Payment Methods

Flexible payment terms available: T/T and L/C. For new clients, 30% advance payment for production, balance against copy of B/L. L/C is acceptable for large & regular orders to secure both parties.

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
