Material knowledge of aluminum alloy instrument case

Pure aluminum has low strength and is not suitable for making structural parts under load.Aluminum alloy with high strength can be made by adding proper amount of silicon, copper, magnesium, manganese and other alloying elements into aluminum.  

According to characteristics of aluminum alloy composition and production process, usually divided into two major categories of deformation and the casting of aluminium alloy. Major in industrial application are aluminum and manganese, aluminum, magnesium, aluminum - magnesium - copper, aluminum - magnesium - silicon - copper, aluminum and zinc - magnesium - copper alloy etc. Deformation of aluminium alloy is also called cooked aluminum alloy, according to its composition and performance characteristics is divided into antirust aluminium, dural, super-hard aluminum, forging and special aluminium etc. Five.

Aluminium alloy aviation case is pure aluminium to join a few alloy element to make, if aluminium - manganese alloy, aluminium - copper alloy, aluminium - copper - magnesium series hard aluminium alloy, aluminium - zinc - magnesium - copper series superhard aluminium alloy.Aluminum alloy has better physical and mechanical properties than pure aluminum: easy to process, high durability, wide range of application, good decorative effect, rich color.Aluminum alloy is divided into rustproof aluminum, duralumin, super duralumin and other categories. Each category has its own scope of use, and has its own code for users to choose.
