Abstract

The invention relates to an air busbar and a preparation method thereof and belongs to the field of metal materials. A metal housing of the busbar is made with aluminum-magnesium alloy, specially, Sipowder, Mg powder, hydrides, Ni powder, Sn powder and Al powder. The hydrides are added into the aluminum alloy; the added elements are fused in the alloy; the process of not external guidance but character itself is provided; purity of a material can be fully guaranteed, invasion of impurities is avoided; the metal shell is made via the steps of burdening, forming, and sintering and the like; thetechnique is simple and suitable for large-scale production; ceramic membrane is formed on the surface of the alloy, providing very high hardness and corrosion resistance and fully extending the service life.
