Abstract

The invention discloses a bacteriostatic aluminum alloy for an automobile pipeline. The bacteriostatic aluminum alloy is prepared from chemical components including, by weight, 0.4%-0.5% of Si, 0.1%-0.25% of Fe, 0.15%-0.25% of Mn, 2.5%-4.5% of Mg, 0.1%-0.25% of Zn, 0.05%-0.1% of Sc, 0.45%-0.8% of Li, 0.01%-0.1% of Cu, 0.01%-0.1% of Cr and the balance Al and inevitable impurities. Multiple elementssuch as Sc, Li and the like are added on the basis of a traditional aluminum alloy, so that the aluminum alloy has the characteristics of corrosion resistance, high ductility and the like, surface treatment is performed on the aluminum alloy by the aid of a heat-insulating bacteriostatic powder coating, the coating is prepared from main components including silica powder and calcined shell powder, and thus the alloy has the very good heat-insulating effect; and meanwhile, nano titanium dioxide is added, so that the alloy has the good bacteriostatic effect, and the long-term bacteriostatic effect can be 60% or above.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to an antibacterial aluminum alloy for automobile pipes and a processing method thereof. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. Aluminum alloy is currently the most widely used alloy. [0003] However, due to the many parts of the car, the working environment is different, and the requirements for its properties are also different. Especially during the use of the car pipeline, due to the high temperature, it is easy to be corroded, and it is easy to cause safety hazards; a...
