As we all know, the word ladder engineering ladder are generally made from aluminum is made, so why would be the word aluminum ladder stuff?

Aluminum is a general term for aluminum-based alloy. Major alloying elements are copper, silicon, magnesium, zinc, manganese, minor alloying elements are nickel, iron, titanium, chromium, lithium and so on.

Low density aluminum ladder, but the intensity is relatively high, close to or more than high quality steel, plastic, it can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, usage after steel.

Aluminum ladder divided into two categories: cast aluminum alloy, in the case of using cast; deformation of aluminum alloy, can withstand pressure processing, mechanical properties than cast. Processed into various forms, specifications of aluminum material. Mainly for the manufacture of aviation equipment, daily necessities, building doors and windows.

Aluminum alloy processing methods can be divided into deformation of aluminum and cast aluminum. Deformation is divided into non-heat strengthened aluminum alloy and heat treatment strengthened aluminum alloy. Enhanced heat treatment can not by heat treatment to improve mechanical properties, can only be achieved by cold deformation strengthening, which includes high purity aluminum, industrial high purity aluminum, industrial aluminum and rust-proof aluminum. Heat treatable aluminum alloy can be used to improve the mechanical properties by quenching and aging heat treatment, it can be divided into hard aluminum, wrought aluminum, super-hard aluminum and special aluminum alloy.

Some heat-treated aluminum ladder may be employed to obtain good mechanical properties, physical properties and corrosion resistance.

Cast aluminum alloy can be classified according to chemical composition of Al-Si alloys, aluminum-copper alloy, aluminum-magnesium alloy, aluminum, zinc alloy and aluminum rare earth alloy, Al-Si alloys and simple Al-Si alloy (heat treatment can enhance the mechanical properties of the lower casting good performance), a special aluminum-silicon alloy (heat treatment can be enhanced, high mechanical properties, good casting performance)

2008 Beijing Olympic Torch "clouds" of the material is aluminum.
