Sulphuric soft anodising, also known as Type II anodising, is a specific type of anodising process that involves immersing the metal workpiece into a sulphuric acid electrolyte solution.
Unlike hard anodising, which creates a thicker and more durable oxide layer, soft anodising produces a thinner oxide layer on the surface of the metal.
The resulting oxide layer formed during soft anodising provides several benefits, including improved corrosion resistance, enhanced paint adhesion, and electrical insulation properties. Soft anodising is commonly used for decorative purposes, as it can produce a range of colours when dyeing is applied after the anodising process.
Overall, sulphuric soft anodising offers a versatile and cost-effective solution for a variety of applications where a durable and aesthetically pleasing surface finish is desired, but where the extreme hardness and wear resistance of hard anodising are not necessary.
