Chemical polishing aluminium extrusion profile is the purpose of polishing the surface of the workpiece on the surface of the concave and convex surface by the polishing solution, and the dissolution rate is different.
The chemical polishing of aluminum alloy can be divided into two kinds: alkaline polishing and acid polishing.
The degree of leveling of metal surface is very uniform by chemical polishing. Meanwhile, the surface after chemical polishing has better durability than the surface brightness of mechanical polishing.
