What Are The Two Main Categories Of Aluminum Alloy Ladders?

Aug 30, 2017

Aluminum alloy ladder is divided into two categories: cast aluminum alloy, in the use of the casting, deformation of aluminum alloy, can withstand pressure processing, mechanical properties are higher than the casting state. Machinable into various forms, specifications of aluminum alloy. Mainly used in the manufacture of aviation equipment, daily necessities, building doors and windows and so on.

Aluminum alloy According to the processing method can be divided into deformed aluminum alloy and cast aluminum alloy. Deformed aluminum alloy is also divided into non heat-treated reinforced aluminum alloy and heat-treatable reinforced aluminum alloy. Non-heat treatment can not be enhanced by heat treatment to improve mechanical properties, only through cold processing deformation to achieve strengthening, it mainly includes high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum and rust-proof aluminum and so on. Heat-treated reinforced aluminum alloy can be quenched and aging by means of heat treatment to improve mechanical properties, it can be divided into hard aluminum, wrought aluminum, superhard aluminum and special aluminum alloy.

Some aluminum alloy ladders can be treated with heat treatment to obtain good mechanical properties, physical properties and corrosion resistance.

Cast aluminum alloy by chemical composition can be divided into aluminum-silicon alloy, aluminum-copper alloy, aluminum-magnesium alloy, aluminum-zinc alloy and rare-earth alloy, aluminum-silicon alloy has a simple al-Si alloy (not heat-treatment hardening, low mechanical properties, good casting performance), special aluminum-silicon alloy (can be heat-hardening, high mechanical properties, good casting performance).
