Aluminum magnesium alloy oxide film is easy to form, the quality of the film is also better, can be oxidized color, which is an important characteristic of the difference with other alloys; But comparatively speaking, Jiaozuo city Aoxin anti-corrosion materials also have some shortcomings.
Magnesium anodized film has dual character, large porosity and uneven distribution, so it is difficult to achieve the best anticorrosion effect.
Magnesium is hardening and brittle, to reduce the elongation increases, the tendency of hot tearing, such as ADC5, ADC6, in production, because of its wide range of solidification and shrinkage tendency, shrinkage and cracks frequently, the magnesium anode casting performance is poor, therefore, jiaozuo Mr Xin anticorrosive material that has great limitations on its use range, slightly complex workpiece structure, is the production.
Aluminum magnesium alloy commonly used in the market, due to its complex composition, low aluminum purity, magnesium sulfate anodization, difficult to produce transparent protective film, mostly milky white, color state is poor, according to the normal process is difficult to achieve the ideal effect.
