Alluminium Alloy 7075 Angles & Flats

What are Alluminium Alloy 7075 Angles & Flats?

Alluminium Alloy 7075 is a high-strength Alluminium alloy primarily alloyed with zinc, along with magnesium and copper. It is one of the strongest Alluminium alloys available and is widely used in applications requiring high strength and durability. Angles and flats are structural components used for support, framing, and fabrication in demanding environments.

Key Functions:

• Provide extremely high strength
• Enable lightweight structural design
• Offer excellent fatigue resistance
• Ensure durability under heavy loads

Chemical Composition of Alluminium Alloy 7075

Typical Composition:

• Alluminium (Al): Balance
• Zinc (Zn): 5.1% – 6.1%
• Magnesium (Mg): 2.1% – 2.9%
• Copper (Cu): 1.2% – 2.0%
• Chromium (Cr): 0.18% – 0.28%
• Iron (Fe): ≤ 0.5%
• Silicon (Si): ≤ 0.4%

This composition provides exceptional strength and mechanical performance.
