Aluminum alloy ladder, aluminum alloy is also a type of non-ferrous metal structure material widely used in industry.  Because the aluminum alloy used in aluminum alloy ladders has low density, but high strength and good plasticity, aluminum alloy ladders have good corrosion resistance, and have better physical and mechanical properties than pure  aluminum, easy to process, high durability, and application  It has a wide range, good decorative effect and rich colors.  The aluminum alloy ladder still maintains the characteristics of light weight, but the mechanical properties are significantly improved.


Aluminum alloy ladders are low in cost and have good heat dissipation, which is much safer than iron ladders  .  Aluminum alloy ladders are divided into two categories: cast aluminum alloy, which is used in the as-cast state; deformed aluminum alloy, which can withstand pressure processing, and has higher mechanical properties than the as-cast state. It can be processed into various shapes and specifications of aluminum alloy materials. Mainly used  Manufacturing aviation equipment, daily necessities, doors and windows for construction, etc.


Cast aluminum alloy can be divided into aluminum silicon alloy, aluminum copper alloy, aluminum magnesium alloy, aluminum according to chemical composition  Zinc alloys and aluminum rare-earth alloys, of which aluminum-silicon alloys include simple aluminum-silicon alloys (cannot be heat-treated for strengthening, lower mechanical properties, and good casting performance), special aluminum-silicon alloys (heat-treatable strengthening, higher mechanical properties, and good casting performance)  , Basically understand some of the high-quality characteristics of aluminum alloy ladders, which has a good reference value for us to buy ladders in the future.  Lifts are widely used in various building decoration and various low-altitude operations. There are many different types and materials of lifts. Generally, they are made of aluminum alloy. Linyi lift manufacturers introduced us to the benefits of using aluminum alloy materials.  .


Using high-strength high-quality aluminum alloy material, beautiful appearance, small size, light weight, stable lifting, safe and reliable  Etc.  The product has a solid structure, large carrying capacity, stable lifting, simple and convenient installation and maintenance, and is an economical and suitable ideal cargo conveying equipment between low floors.  The whole is made of high-strength aluminum profiles. Due to the high strength of the profiles, it has beautiful appearance, small size, light weight, compact structure, convenient movement, and liftingThe platform is stable, easy to operate, safe and reliable, which makes high-altitude operations more convenient and quick. It can walk at fast and slow speeds with adjustable speed. It is an ideal medium and low-altitude operation equipment for efficient and safe production of modern enterprises.


Cast aluminum alloy can be divided into aluminum silicon alloy, aluminum copper alloy, aluminum magnesium alloy, aluminum according to chemical composition  Zinc alloys and aluminum rare-earth alloys, of which aluminum-silicon alloys include simple aluminum-silicon alloys (not heat-treated for strengthening, lower mechanical properties, and good casting performance), special aluminum-silicon alloys (heat treatment strengthening, higher mechanical properties, and good casting performance)  .  Aluminum alloy ladders have low density, but high strength, close to or exceed high-quality steel, good plasticity, and can be processed into various profiles. They have excellent electrical conductivity, thermal conductivity and corrosion resistance. They are widely used in industry, and the amount of use is second only to  steel.
