What is Hard Anodizing?

Hard anodizing, also known as Type III anodizing, is a thicker, more robust anodizing process compared to standard anodizing methods. It significantly increases corrosion resistance, wear resistance, and electrical insulation. The resulting coating can reach a thickness up to 0.020 inches, making it suitable for applications requiring rigorous durability.

Key Applications of Hard Anodizing Equipment

Hard anodizing equipment serves a multitude of purposes across various industries. Here are some of the most common applications:

• Aerospace Industry: Hard anodized components, such as aircraft fittings and brackets, benefit from weight reduction and enhanced durability.
• Automotive Industry: Engine components, transmission housings, and decorative trims utilize hard anodizing for improved wear resistance and aesthetic appeal.
• Medical Devices: Surgical instruments and equipment undergo hard anodizing for increased hygiene and resistance to corrosion.
• Marine Applications: Components exposed to harsh saltwater environments can withstand corrosion with hard anodizing.
