Sandblasted white
Sandblasted white is produced by first subjecting the workpiece to sandblasting and then performing anodizing. Sandblasting mattifies the treated areas, creating a sand‑finished surface, while also removing burrs, casting slag, and other defects and contaminants from the workpiece’s surface. This process enhances the mechanical properties of aluminum alloys, strengthens the metal’s surface, and reduces stress and fatigue.
The main applications of anodizing include:
(1) Enhance the wear resistance, corrosion resistance, and weathering resistance of parts.
(2) The transparent oxide film formed through oxidation can be colored to produce various tinted films.
(3) As a dielectric film in capacitors.
(4) Enhance adhesion to organic coatings and serve as a primer.
(5) Used as a base layer for electroplating and enamel coating.
(6) Other applications currently under development include solar‑absorbing panels, ultra‑hard coatings, dry lubricant films, catalytic films, nanowires, and the deposition of magnetic alloys within porous membranes for use as memory elements.
