Aluminum alloy is widely used in daily life, and many products are made of aluminum alloy. However, aluminum alloy forging and aluminum die casting are two different methods.
Forged aluminum is a forged aluminum alloy, codenamed LD. Including Al Mg Si Cu forged aluminum alloy and Al Mg Si forged aluminum alloy, mainly used for forging complex shapes. Magnesium and silicon can form a strengthening phase Mg2Si; Copper can improve Hot working and form strengthening phase Cu4Mg5Si4Al; Manganese can prevent overheating during heating. Wrought aluminum alloys are mainly used for quenching and artificial aging. After quenching, artificial aging should be carried out immediately, otherwise the strengthening effect will be reduced. Wrought aluminum alloys have lower high-temperature strength and good thermoplastic properties, which can be forged into complex shaped forgings and die forgings, as well as rolled into plates or other profiles.
Cast aluminum alloys are divided into four categories: aluminum silicon, aluminum copper, aluminum magnesium, and aluminum zinc. For cast aluminum alloys, in addition to the required mechanical properties and corrosion resistance, they should also have good casting performance. Execution. When casting aluminum alloy, the combination of its casting performance and mechanical properties is better. Cast aluminum alloys have good castability, low density, excellent corrosion resistance, heat resistance, and weldability; Used for manufacturing castings with complex shapes but low strength requirements, such as aircraft, instrument shells, etc; High strength castings with complex shapes. Such as motor casing, cylinder body, fan blades, engine pistons, etc.
Cast aluminum and forged aluminum have almost no difference in appearance, but there are significant differences in metal properties. Forged aluminum has higher toughness, impact resistance, strength, and load-bearing capacity than cast aluminum, and the difference in heat dissipation performance is not significant.
