What advantages does c have over common industrial aluminum?

Ordinary building and general machinery aluminum alloys have low strength and poor fatigue resistance, easy to deform or crack under repeated dynamic loads. Aviation aluminum alloy achieves several times higher tensile strength after solution and aging heat treatment while retaining low density, greatly reducing aircraft dead weight to save fuel and extend voyage. It also undergoes strict purification to reduce impurity content, presenting superior low-temperature toughness, stress corrosion resistance and dimensional stability to adapt complex high-altitude flight environments that regular aluminum cannot withstand.
