Case

Aluminum parts are deoxidized and inner holes are polished to remove burrs without affecting the accuracy of the workpiece.

Removing oxide layers from aluminum parts is a critical step in surface preparation to ensure optimal adhesion, corrosion resistance, and finish quality. Common methods include chemical treatments like acid or alkaline etching, mechanical abrasion (e.g., sandblasting or grinding), and electrolytic processes such as anodizing reversal. The choice depends on the part's application, oxide thickness, and desired surface properties. Post-treatment cleaning with solvents or deionized water is often required to eliminate residues. Proper oxide removal enhances performance in industries like aerospace, automotive, and electronics, where aluminum's lightweight durability is essential.
