High Melting Point 2050°C Hard Anodized Aluminum Parts 25-250 Microns Custom Sizes

Hard anodizing is a specialized surface treatment technology for aluminum and aluminum alloys, creating a thick oxide film with exceptional properties. This electrolytic process produces components with superior durability and performance characteristics.

• Maximum oxide film thickness of approximately 250 microns
• Microhardness up to 1500 kg/mm² on pure aluminum (400-600 kg/mm² on alloys)
• High melting point (2050°C) and electrical resistivity
• Breakdown voltage up to 2000V after sealing treatment
• Excellent corrosion resistance and wear properties
• Strong bonding with substrate metal

• Surface hardness reaches HV500 on aluminum alloys
• Film thickness range: 25-250 microns
• 50% penetration into substrate with 50% surface adhesion
• Exceptional wear resistance (1.5-3.5 mg/1000 revolutions)
• Non-toxic process and final product
• Two primary methods: Sulfuric acid DC method (most common) and Oxalic acid AC/DC method

Hard anodized aluminum parts are ideal for components requiring:

• High wear resistance
• Thermal stability
• Electrical insulation
• Corrosion protection

Widely used in aerospace, automotive, medical devices, electronics, and precision mechanical components where durability and performance are critical.
