The 7075 aluminum circle is a premium aluminum alloy disc (AA7075) known for its high strength-to-weight ratio, excellent fatigue resistance, and good machinability. Made from the high-performance 7000 series aluminum alloy, it is alloyed mainly with zinc, magnesium, and copper, offering one of the strongest lightweight materials in the wrought aluminum family. This alloy is precipitation hardened, making it suitable for demanding structural, aerospace, and industrial applications requiring durability and stability under load.

7075 aluminum circles are typically supplied in various tempers (such as T6, T3, T651) and forms (hot-rolled, cold-rolled, proof machined) to support both standard and custom machining or fabrication processes. These discs are available with mill or custom finishes and optional coatings for enhanced performance.
