🔧 Sulphuric Anodising – High‑Quality Aluminium Anodising Services
Sulphuric anodising (Type II anodising) is the most popular and versatile aluminium anodising process, offering an excellent balance of durability, corrosion resistance, and aesthetic appeal. Ideal for both industrial and decorative applications, sulphuric anodising enhances the performance and appearance of aluminium components while maintaining precise dimensional control.
⭐ Benefits of Sulphuric Anodising
- Superior Corrosion Protection Creates a protective oxide layer that shields aluminium from moisture, chemicals, and environmental exposure.
- Enhanced Surface Hardness Improves wear resistance, making components more durable and long‑lasting.
- Excellent Colouring Capability The porous anodised layer absorbs dyes effectively, allowing for a wide range of decorative colours and finishes.
- Consistent, High‑Quality Finish Produces a smooth, uniform surface ideal for consumer products, architectural elements, and precision‑engineered parts.
- Lightweight and Environmentally Friendly Anodising strengthens aluminium without adding weight or using hazardous coatings.
⚙️ Common Applications
Sulphuric anodising is widely used across industries, including:
- Electronics and consumer products
- Architectural and decorative aluminium
- Automotive and aerospace components
- Precision engineering and machined parts
🧪 How the Sulphuric Anodising Process Works
During the process, aluminium components are immersed in a sulphuric acid electrolyte and exposed to a controlled electrical current. This transforms the outer surface of the metal into a durable aluminium oxide layer that becomes an integral part of the component. The finish can be left natural, dyed in various colours, or sealed for enhanced corrosion resistance.
