Abstract

A colorable die-cast Al-alloy contains Si (9.5-31 wt.%), Fe (0-1.5), Mn (0-0.6), Cu (0-0.8), Zn (0-0.3) and Al (rest). The black or bronze color can be dyed on its surface.

Description

technical field [0001] The invention relates to new alloy materials, in particular to a colorable die-casting aluminum alloy. Background technique [0002] As a type of aluminum alloy, die-casting aluminum alloy contains more alloying elements, which makes it difficult to carry out coloring treatment, and it is difficult to form a good and stable film layer. With the wide application of aluminum alloy products and the improvement of people's living standards, there are more and more demands for surface decoration and anti-corrosion functions of some aluminum alloy products. In order to adapt to general decoration with certain mechanical properties and good corrosion resistance In order to meet the requirements of large-scale production of parts, there is an urgent need for a colorable die-casting aluminum alloy in the market. Contents of the invention [0003] The object of the present invention is to solve the shortcomings of the above-mentioned background technology, an...
