Aluminum and aluminum alloys have the advantages of high mechanical strength and ductility, easy processing, high specific strength, and light weight, and are widely used in the fields such as construction, hardware, electronics, automobile, shipbuilding, aircraft, aerospace, etc. Due to the active amphoteric properties of aluminum and aluminum alloys, they must undergo passivation, oxidation, plating, and other related treatments to achieve anti-corrosion performance. With the gradual maturity of aluminum and aluminum alloy plating technology, the diversification of decorative properties and the improvement of anti-corrosion performance, more and more aluminum and aluminum alloy accessories are being surface treated with plating. Tele Aluminum housing, especially those used in electronic products, must undergo plating treatment due to special electronic requirements.
