Medical equipment holder Material: Aluminium 6061. Surface treatment: anodised blue. Features: strong corrosion resistance, light weight, excellent processing performance, good corrosion resistance, high toughness and no deformation after processing, easy to apply colour film, excellent oxidation effect After the oxidation of aluminium alloy, the surface film is porous, which can easily absorb harmful substances and make the surface of aluminium alloy products easy to be corroded or polluted, so the surface needs to be sealed before use to improve the anti-pollution and corrosion resistance of the oxide film. The principle of the anodic oxidation method is essentially the electrolysis of water.
