What is Anodizing?
Anodizing is an electrochemical process: it creates a durable, porous oxide layer integrated with the metal (not just a surface coating that peels). It’s most commonly used for aluminum and titanium.
What does anodizing do for your custom parts?
√ Boosts corrosion resistance (prevents rust/oxidation)
√ Enables custom colors (clear, black, blue, red—see anodizing colors for aluminum)
√ Improves wear resistance (ideal for high-use parts like gears)
√ Enhances adhesion for follow-up coatings (paint, labels)
Our anodizing process is tailored to your needs:
Controls anodizing thickness (5–100 microns, based on durability needs)
Handles small batch anodizing (prototypes) or large aluminum parts (industrial equipment)
Works with aluminum (primary) and titanium (for medical/aerospace parts)
Our Anodizing Services & Application Scenarios
| Anodizing Service Type | Suitable Materials | Key Application Scenarios | Core Advantages |
| Type 2 Anodizing（Type II） | Aluminum | Phone frames, automotive trim, small aluminum parts | Thin layer (5–20μm), cost-effective, great for color |
| Type 3 Anodizing（Hard Coat） | Aluminum | Machinery gears, aerospace parts, high-wear tools | Thick layer (25–100μm), extreme wear/corrosion resistance |
| Color Anodizing | Aluminum | Electronic housings (blue/red), decorative parts (gold/white) | 200+ colors, uniform finish, long-lasting |
| Clear Anodizing | Aluminum, Titanium | Medical devices, architectural parts | Retains natural look, boosts corrosion resistance |
| Titanium Anodizing | Titanium | Surgical implants, aerospace fasteners | Biocompatible, heat-resistant, voltage-controlled colors |
| Chromic Acid Anodizing | Aerospace-grade Aluminum | Aircraft components, military parts | Thin/uniform layer, meets aerospace standards |

Anodizing Applications Across Industries
Our anodizing services solve sector-specific needs—matching the right process to your parts:
Automotive
Hard anodizing aluminum for engine brackets (resists oil/heat); black anodizing aluminum for wheel rims (scratch-proof).
Electronics
Color anodizing for phone midframes (blue/red for brand identity); Type 2 anodizing for charger housings (affordable durability).
Aerospace
Type 3 anodizing for large aluminum parts (high wear resistance); chromic acid anodizing for fasteners (aerospace standards).
Medical
Titanium anodizing for implants (biocompatible); clear anodizing for instrument handles (easy to sterilize).
Consumer Goods
Gold anodizing for decorative parts (luxury look); white anodizing for kitchen appliances (stain-resistant).
Key Anodizing Comparisons
Clients often ask about process/type differences—here’s a simple breakdown:
| Comparison Topic | Option A | Option B | Best For |
| Type 2 vs Type 3 Anodizing | Thin (5–20μm), cheap, color-friendly | Thick (25–100μm), tough, no bright colors | Type 2: Consumer parts; Type 3: Industrial/high-wear parts |
| Anodizing vs Electroplating | Oxide layer = part of metal (no peel) | External coating (risk of chipping) | Anodizing: Long-term use; Electroplating: Decorative parts |
| Anodizing vs Powder Coating | Thinner, better heat resistance | Thicker, higher impact resistance | Anodizing: Precision parts; Powder Coating: Large structures |
Why Choose Our Anodizing Services?
👉 Full Customization
Handle small batches (prototypes) to large aluminum parts; match any anodizing color (brand RGB) or thickness.
👉 All Types Covered
Type 2, Type 3 hard coat, titanium anodizing—no need for multiple vendors.
👉 Strict Quality Checks
Every part passes thickness tests and color uniformity inspections (meets ISO 9001).
👉 Eco-Friendly Process
Our anodizing tanks use low-waste chemistry; we recycle water/chemicals (compliant with global environmental rules).
Frequently Asked Questions
Can you anodize large aluminum parts (e.g., 2m+ long)?
Yes—our anodizing plant has 3m+ tanks for industrial/aerospace large parts.
How long do anodizing colors last?
5–10 years outdoors (UV-resistant); 10+ years indoors—way longer than paint.
When to pick hard anodizing (Type 3) vs Type 2?
Hard anodizing = high-wear parts (gears, pistons); Type 2 = decorative/light-use parts (electronics trim).
