CNC machining aluminum alloy parts

【Part name】 CNC machining aluminum alloy parts automation equipment fixed connecting rod

【Manufacturing process】 CNC milling, middle wire cutting

【Product Features】 High precision  complex structure

【Material used】 Aluminum alloy 7075-T6

Mainly zinc, but sometimes a small amount of magnesium  copper are added. Among them, super-hard aluminum alloys contain zinc, lead, magnesium  copper alloys close to the hardness of steel. The extrusion speed is slower than the 6 series alloy,  the welding performance is good. 7005  7075 are the highest grades in the 7 series  can be strengthened by heat treatment.

The main feature is that the hardness of 7075 is a high-hardness, high-strength aluminum alloy, which is often used in the manufacture of aircraft structures  futures. It requires the manufacture of high-stress structural parts  molds with high strength  strong corrosion resistance. At present, basically relying on imports, my country's production technology needs to be improved.

【Surface treatment】Natural anodizing

Aluminum is a relatively active metal with a standard potential of -1.66v. It can naturally form an oxide film with a thickness of about 0.01 to 0.1 microns in the air. This oxide film is amorphous, thin  porous,  has poor corrosion resistance. However, if aluminum  its alloys are placed in an appropriate electrolyte, the aluminum product is used as the anode,  an oxide film is formed on the surface under the action of an external current. This method is called anodic oxidation.

【Benefits after treatment】 The surface treatment is more resistant to corrosion. The oxide film can absorb dyes of many colors, so aluminum products can be made into various colors. This layer of color is  only a protective film, but also a decorative film. This film layer  only has higher hardness  thickness, but also has low roughness that can increase the wear resistance of aluminum products.
