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.
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;
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.
