Introduction of sandblasted anodizing 6061 aluminum tube

The main alloying elements of 6061 aluminum alloy are magnesium and silicon, which have medium strength, good corrosion resistance, weldability, and good oxidation effect. Sandblasted anodizing 6061 aluminum tube is an additional sandblasting step after the aluminum profile is aged and before oxidation. Sandblasting oxidation is to slowly pass the aluminum tube through the sandblasting machine, and the inside of the sandblasting machine will spray very fine emery pellets to make even small pits on the surface of the aluminum tube. milder than that. Emery has different mesh numbers, the larger the mesh, the finer the sand.

Advantages of sandblasted anodizing 6061 aluminum tube

  • 1. The matte aluminum tube feels more gentle and low-key.
  • 2. The sandblasted aluminum pipe can conceal the extrusion pattern (extrusion aluminum pipe will have extrusion pattern).
  • 3. Sandblasting can remove tiny burrs and protrusions on the aluminum tube.
  • 4. Sandblasting can also remove the oxide film on the surface of the aluminum tube, so the sandblasting process must be before the oxidation process.

Chemical composition of sandblasted anodizing 6061 aluminum tube:

Cu: 0.15 to 0.4; Mn: 0.15; Mg: 0.8 to 1.2; Zn: 0.25; Cr: 0.04 to 0.35; Ti: 0.15; Si: 0.4 to 0.8; Fe: 0.7;

Application of sandblasted anodizing 6061 aluminum tube:

It is widely used in various industrial structural parts that require certain strength and high corrosion resistance, such as the manufacture of trucks, tower buildings, ships, and trams.
