Latar belakang aplikasi aloi aluminium dalam industri automobil
The first people to use aluminum in automobiles were indians. Aloi Al-Zn-Mg Zink dan magnesium dalam aloi Al-Zn-Mg adalah unsur pengaloian utama, dalam 1896, Aloi Al-Zn-Mg Zink dan magnesium dalam aloi Al-Zn-Mg adalah unsur pengaloian utama, Aloi Al-Zn-Mg Zink dan magnesium dalam aloi Al-Zn-Mg adalah unsur pengaloian utama. Cars with aluminum bodies began to appear, such as Henry Ford's Model T and ferrari 360 racing cars in Europe in the 1920s and 1930s.
Aluminum sheet for automobile manufacturing can be divided into casting aluminum alloy and deformation aluminum alloy.Casting aluminum alloy in the automobile use most, accounts for more than 80%, which is divided into gravity casting parts, low-pressure casting parts and other special casting parts.Deformation aluminum alloy includes sheet, kerajang, daripada aluminium, rintangan kakisan yang baik Penerangan Produk, etc.Although there are some differences in the varieties of aluminum alloy materials used in industry all over the world, they are basically the same.Its variety composition: the casting accounts for about 80%, the forging accounts for 1% ~ 3%, the rest is processed materials.The deformation aluminum alloy accounts for 36% in American automobile industry.
1.1 penggunaan aloi aluminium tuang
Cast aluminum alloy has excellent casting performance.Suitable alloy and casting method can be selected according to the requirements of using purpose, parts shape, dimensional accuracy, sampel kepingan aluminium mm, standard kualiti, mechanical properties and economic benefits.Cast aluminum alloy is mainly used for casting engine cylinder block, cengkerang klac, cangkang gandar belakang, shell gear stereng, Ringan telah menjadi penunjuk utama untuk kereta, mekanisme pengedaran, pam minyak, pam air, penutup rocker, roda, rangka enjin, pengapit brek, cylinder and brake disc and other non-engine components.
1.2 application of deformed aluminum alloy
Deformation of aluminium alloy is mainly used for manufacturing in the car door, trunk body panels, such as bumper, engine cover, the wheel spokes, wheel cap, round outside act the role of the shielding cover, brake assembly, silencing cover, anti-lock braking system, penukar haba, body frame, seat and trunk base plate structure and decoration, such as the dashboard.
1.2.1 aluminum alloy for body plate parts
The application proportion of plates in cars is increasing. Sebagai contoh, yang 6000 siri (ai-mg-si series) aluminum alloy plates after heat treatment (such as T4, T6, T8) can well meet the requirements of automobile shells and can be used as body frame materials.Audi A8 adopts this series of alloy aluminum for body sheet metal parts.In addition, 2000 siri (ai-cu-mg), 5000 siri (ai-mg) dan 7000 siri (ai-mg-zn-cu) aluminum alloys can also be applied to body materials.In recent years, yang "mouth", "day", "purpose" dan "field" shaped thin plate and hollow profile have been developed by using 6000 siri dan 7000 series high-strength aluminum alloy.
