Aluminum Anodizing services
ISO 9001 Certified | MIL-PRF-8625 Compliant
At Chihenghardware, our aluminum anodizing service combines advanced technology with industry expertise to deliver superior metal finishing solutions. If you’re wondering, “How does our aluminum anodizing work?”—here’s a breakdown of our proven process designed for durability, quality, and cost-efficiency:
Surface Preparation
Your aluminum components undergo meticulous cleaning and etching to remove impurities, ensuring optimal adhesion during anodizing.
Electrochemical Anodizing
We immerse parts in a controlled sulfuric acid bath, applying electrical current to create a porous oxide layer. This step enhances corrosion resistance and forms the base for color dyeing (if required).
Sealing & Finishing
The anodized layer is sealed to lock in durability and aesthetics, resulting in a hard, non-conductive finish resistant to wear and UV degradation.

Types of Aluminum Anodizing Services
Clear Aluminum Anodizing Service
Decorative Finish
Clear anodizing creates a smooth, natural aluminum appearance ideal for architectural trim, consumer electronics, and luxury products. The process preserves metal’s metallic shine while adding a protective layer.
Corrosion Resistance for Clear Anodizing
This service enhances aluminum’s innate corrosion resistance, making it suitable for outdoor fixtures, marine hardware, and medical equipment exposed to moisture or chemicals.
Color Aluminum Anodizing Service
Decorative Finish Options
Choose from matte, glossy, or textured finishes to align with brand aesthetics. Popular for consumer goods like smartphones, appliances, and automotive trims.
Durable Color Anodizing
Electrolytic coloring bonds pigments deep within the oxide layer, ensuring colors resist fading from UV exposure or abrasion.
Wide Range of Colors
Match Pantone codes or select standard hues (black, gold, red, blue) for consistent branding across industrial or retail products.
Hard Anodizing Service
Wear Resistance for Hard Anodizing
Hard anodizing (Type III) produces a dense oxide layer (up to 0.003”), ideal for high-friction parts like hydraulic cylinders, firearm components, and industrial gears.
Surface Hardness Improvement
Achieve surface hardness up to 60-70 Rockwell C, surpassing untreated aluminum’s 15-20 Rockwell B, for extended part lifespan.
Applications in Aerospace
Used for aircraft landing gear, engine mounts, and satellite components requiring lightweight durability.
Applications in Automotive
Enhances brake pistons, transmission parts, and suspension systems exposed to extreme temperatures and wear.
Sulfuric Acid Anodizing Service
Common Anodizing Process
Sulfuric acid (Type II) is the most widely used method, balancing cost and performance for general-purpose applications like machinery parts and enclosures.
Cost-Effective Anodizing Solution
Delivers corrosion resistance and dye adhesion at 30-50% lower cost than specialized processes, ideal for high-volume orders.
Chromic Acid Anodizing Service
Corrosion Protection Focus
Chromic acid (Type I) forms thin, non-conductive coatings (0.00001”-0.00004”) preferred for aerospace fasteners and components in saltwater environments.
Specific Industry Applications
Mandated for military aircraft (per MIL-A-8625) and critical medical devices where electrical conductivity must be minimized.
MIL-A-8625 Standard
Compliant with U.S. military specifications for adhesion, salt spray resistance (500+ hours), and coating uniformity.
