Anodized Parts in China
If your aluminum components need improved corrosion resistance, surface hardness, or a specific colour finish, sourcing anodized parts from verified Chinese suppliers is a cost-effective solution. China has a large base of anodizing specialists that serve global clients in electronics, automotive, aerospace, and consumer products. As part of Haizol's finished metal products directory, verified suppliers are pre-screened for capability and certifications.
Chinese anodizing suppliers offer Type II (sulphuric acid) and Type III (hard anodizing) processes, with colour options including clear, black, red, blue, gold, and custom shades. Many factories combine CNC machining with in-house anodizing, delivering fully finished anodized parts from a single facility. This eliminates the need to coordinate separate machining and finishing vendors.
Verified anodizing suppliers on Haizol hold ISO 9001 certification, and many comply with MIL-A-8625 standards for aerospace applications. Their quality systems include coating thickness measurement, salt spray testing, and colour consistency checks. Many factories also produce other finished metal products. Many buyers combine this with CNC machined parts from the same platform.
The risk when sourcing anodized parts offshore is colour inconsistency between batches and poor masking on surfaces that should remain uncoated. For related needs, explore extruded products from verified factories on Haizol.
Haizol matches your RFQ with verified suppliers experienced in anodizing. You receive multiple quotes, typically within 24 hours, and communicate directly with the factory. Design files are protected through configurable NDA options.
Frequently Asked Questions
What Is the Difference Between Type II and Type III Anodizing?
Type II anodizing produces a thin oxide layer (5–25 μm) for corrosion protection and colour. Type III (hard anodizing) creates a thicker layer (25–75 μm) for wear resistance and durability. Specify your anodizing type in your RFQ.
Does Anodizing Change Part Dimensions?
Yes, slightly. Anodizing builds approximately one-third outward and two-thirds inward. Type II adds roughly 5–13 μm per surface. Factor this into your tolerance calculations when designing anodized parts.
What Colours Are Available for Anodized Parts?
Standard colours include clear, black, red, blue, gold, and green. Custom colours can be matched to Pantone or RAL references. Specify your colour requirement in the RFQ.
Can Suppliers Combine CNC Machining and Anodizing?
Yes. Many verified factories on Haizol machine and anodize in-house, producing fully finished anodized parts from one supplier. This reduces lead time and ensures tighter quality control.
