Alum Phosphating

Phosphating creates a crystalline phosphate coating for corrosion resistance and paint adhesion. Phosphating is the process of converting a steel surface to iron phosphate. A layer of phosphate coating typically includes iron, zinc or manganese crystals. Zinc phosphating offers the best corrosion resistance and is widely used in automotive applications. It forms a passive oxide film that slows furthur corrosion. Manganese Phosphating on the other hand, is known for its lubrication and wear resistance, ma...
