In recent years, represented by apple iphone's high-end mobile phones have gradually adopted metal shell, aluminum alloy material is most widely used.Compared to earlier years domestic mobile phones common used stainless steel stamping shell, aluminum alloy die-casting mobile phone shell has the following features:

1, hardness, resistance to drop deformation) of aluminum alloy is characterized by high hardness, corrosion resistance is a bit poor.But now with the progress of technology, mobile phone shell used aluminium alloy, already on the corrosion resistance and traditional alloy steel have been neck and neck.

2, shell and adhesive properties of the paint.Refers to the two kinds of metal materials for mobile plating lacquer adsorption performance, easy to understand is mobile phone is easy or not to drop paint.This aluminum alloy than steel, because aluminum molecular gap is big, make the paint adhesion stronger.

3, convenient aluminum parts processing, plastic type is very easy, and mobile phone casing steel if only by stamping forming.So said aluminum alloy shell of mobile phone should be a lot of and modelling diversity, and steel should be very few.
