High-Strength 7075-T651 Aluminum Plate Suppliers from China - Quality Products from Trusted Factory
Characteristic
Key Characteristics
- High strength: 7075 aluminum alloy is one of the strongest commercial alloys, with a strength far superior to that of soft steel.
- Good mechanical performance: It has excellent corrosion resistance, oxidation resistance, and anodic reaction performance.
- Easy to process: Fine grains make deep drilling performance better, tool wear resistance is enhanced, and thread rolling is more unique.
- Good heat treatment effect: After heat treatment, it can achieve very high strength characteristics. Zinc is the main alloying element in 7075. Adding magnesium to alloys containing 3% -7.5% zinc can form MgZn2 with significant strengthening effect, making the heat treatment effect of this alloy much better than that of aluminum zinc binary alloys. Increasing the zinc and magnesium content in the alloy will further enhance its tensile strength, but its ability to resist stress corrosion and peel corrosion will decrease accordingly.
Main Applications
7075 aluminum alloy is widely used in the following fields due to its high strength and good mechanical properties:
- Aerospace: Manufacturing aircraft structures and other high stress structures that require high strength and strong corrosion resistance, such as upper and lower wing panels, beams, frames, etc.
- Mold processing: Used for blow molding (bottle) molds, ultrasonic plastic welding molds, golf ball heads, shoe molds, paper molds, foam molding molds, wax removal molds, etc.
- Mechanical equipment: Fixtures, mechanical equipment components, etc.
- Other Structures: Manufacturing trucks, tower buildings, ships, pipelines, and other buildings that require high strength.
In summary, 7075 aluminum alloy has been widely used in various fields due to its high strength, good mechanical properties, and ease of processing.

Frequently Asked Questions
What are the primary characteristics of 7075 aluminum alloy?
7075 aluminum alloy is known for its exceptionally high strength (far superior to soft steel), excellent mechanical properties, good corrosion resistance, oxidation resistance, and outstanding response to heat treatment and anodizing.
What is the chemical composition of 7075 aluminum alloy?
The main alloying element is Zinc (5.1-6.1%), with Magnesium (2.1-2.9%), Copper (1.2-2.0%), Chromium (0.18-0.28%), and smaller amounts of Iron, Silicon, Manganese, and Titanium, with Aluminum as the margin.
In which industries is 7075 aluminum alloy most commonly used?
Due to its high strength-to-weight ratio, it is widely used in aerospace (aircraft structures, wing panels), mold processing (blow molds, shoe molds), mechanical fixtures, automotive components, engine parts, and marine structures.
Can I get custom-cut sizes for my order?
Yes. Our factory is equipped with multiple fully automated CNC sawing machines to provide precise custom cutting services that meet your exact dimensions and specifications.
How does heat treatment affect the performance of 7075 aluminum?
Heat treatment significantly enhances the alloy's strength. The combination of zinc and magnesium forms MgZn2, which provides a much stronger strengthening effect compared to binary aluminum-zinc alloys.
Are your materials certified?
Yes, all our 7075 aluminum alloy products are supplied with complete material certificates to guarantee compliance with chemical composition and mechanical property standards.
