United Aluminum can supply these alloys, sometimes referred to in the group of “Aerospace Alloys” for their practical applications in the aviation industry.
Aluminum has many benefits over other materials, including a high strength to weight ratio, corrosion resistance, formability, and price. Alloy 6061, 7075, and 2024 are engineered to be lightweight and strong, and their ease of formability allows complex shapes and drawn parts, which can then be further enhanced with heat treating.
United Aluminum can offer Custom Rolled ® Aluminum Coil Strip in these alloys to meet your requirements.
