The aluminum silo is constructed from an aluminum alloy that belongs to the Al-Mg-Si series. This alloy primarily includes magnesium as the main alloying element, offering excellent formability and cold workability. Known for its corrosion resistance, weldability, and moderate strength, it is the most commonly used anti-rust aluminum alloy. This material is notable for its high strength and exceptional fatigue resistance. It exhibits high plasticity and resists corrosion effectively, though it cannot be strengthened through heat treatment. The alloy maintains good plasticity when semi-cold hardened, whereas its plasticity decreases under full cold hardening. It provides good corrosion resistance and weldability, though it has poor machinability. Additionally, this aluminum alloy can be polished.
