7050 Aluminum Plate Sheet

Alloy 7050 aluminum plate sheet is a zinc-magnesium-copper type aluminium alloy for US navy and Air force to provide a high-strength materials resistant to stress-corrosion, primarily for thick-section applications. In addition to its high stress-corrosion resistance, it can be heat-treated and mechanically worked to give a higher toughness at a given strength level than most other 7*** series aluminium alloys.

7050 aluminum plate is mainly used for mold processing, mechanical equipment, tooling fixtures, etc. the mold is especially used for high stress structures requiring high strength and strong corrosion resistance. It is also widely used in aerospace industry, blow molding (bottle) mold, ultrasonic plastic welding mold, golf head, shoe mold, paper mold, foam molding mold, dewaxing mold, mechanical equipment, and used to make high-end aluminum alloy bicycle frame. It will be used as the body material of smartphone oppo N3 for the first time in 2014.

Alloy 7050 aluminum plate sheet is unusual in two respects: it contains zirconium(in place of chromium) to control recrystallization and grain size, and it has a Cu/Mg ratio greater than 0.8. The absence of chromium contributes to the low quench-sensitivity of 7050, and the relatively high copper content results in additional strengthening during second-step aging.

Advantages of 7050 aluminum alloy:

• 1. Aluminum has low density, good conductivity and high thermal conductivity
• 2. Aluminum has good corrosion resistance and excellent insulation performance  
• 3. Aluminum has good formability, connectivity and impact resistance
• 4. The surface of aluminum is very bright, and the surface can be sprayed or anodized
• 5. Aluminum alloy has good recyclability, so aluminum is a very environmentally friendly material 

Alloy 7050 aluminum plate sheet is the principal choice for aerospace applications, especially in the 3-6 inch thickness range. It exhibits better toughness/corrosion resistance characteristics than the older, more established alloy 7075. Since it is less quench sensitive than most other aerospace alloys, this alloy maintains its strength properties in thicker sections while retaining good stress corrosion cracking resistance and fracture toughness levels. AMS 4050 is commonly associated with 7050, though various manufacturers require their own specifications.
