The initial application target of 6013-T4 aluminum alloy research and development is the automotive industry, which improves fuel efficiency by reducing the weight of parts. The corrosion resistance of this alloy is better than that of high-strength 7XXX series alloys, and the strength is higher than that of ordinary 6XXX series alloys and it maintains excellent corrosion resistance and formability. Therefore, the alloy is used in aviation, aerospace, ship, transportation and construction sectors. Both have a wide range of uses.
6013 aluminum alloy is one of the most advanced aluminum alloys in the world today. It has outstanding formability (melting castability, plastic formability, weldability), medium specific strength, good corrosion resistance, and superior damage tolerance. High-quality thermal exposure stability and other grade performance, has a major application background in large civil aircraft, military carrier aircraft, rail transit and other fields.
6013 alloy has increased the content of Cu and Si elements on the basis of 6061. The tensile strength of T6 state is 15%-20% higher than that of 6061 T6. The weldability is equivalent to that of 6061 alloy. It has excellent fatigue, corrosion resistance and machining performance. In 6061 alloy. The yield strength, fatigue strength and fracture toughness of
6013 T6 aluminum sheet is better than those of aluminum-clad 2024 T3 sheet, and the fatigue crack growth rate is low. In addition, the aging treatment of 6013 alloy from T4 to T6 is relatively simple, so 6013 alloy can replace 2024 and 6061 in the aircraft body.
6013 T6 aluminum sheet is mainly used in the fuselage bottom wall, skin, bracket joint, landing gear compartment pressure frame, etc.
