The trade-off between advantages and disadvantages of aluminum alloy in typical scenarios

Building doors and windows: Lightweight, corrosion-resistant, easy to form complex cross-sections, adopting insulation break design to reduce heat conduction
Automobile lightweighting: Reducing weight to enhance range, good energy absorption, using special welding wire (such as 4043) at welding parts
Electronic heat sink: High thermal conductivity, high processing accuracy, surface anodizing to enhance wear resistance
Aerospace structure: High specific strength (7xxx series), avoiding welding, using a composite process of riveting and gluing
