Our Premium Anodizing Capabilities
We offer a comprehensive range of aluminum anodizing and surface treatment services to enhance the durability, corrosion resistance, and aesthetic appeal of your custom hardware components.
Sandblasting Anodizing
Creates a uniform, textured finish by projecting fine abrasive particles onto the surface before the anodizing process. This effectively hides minor machining marks and provides a premium, tactile feel ideal for consumer electronics and high-end hardware.
Hard Anodizing / Type III Anodizing
Engineered for extreme environments, hard anodizing produces a significantly thicker and denser oxide layer. It delivers exceptional wear resistance, high hardness, and superior electrical insulation, making it perfect for heavy-duty industrial parts and machinery components.
Color Anodizing
Transforms your parts with vibrant, long-lasting colors. By introducing custom dyes into the porous oxide layer before sealing, we can achieve a wide spectrum of colors (including black, red, blue, and gold) that will never peel, flake, or chip. Custom color matching is also available.
Matte / Satin Anodizing
Achieves a smooth, low-gloss, and non-reflective surface through specialized chemical etching. This elegant “cloudy” or satin finish provides excellent fingerprint resistance and a modern aesthetic for decorative trims and architectural hardware.
Die-Cast Aluminum Anodizing
A highly specialized process tailored for die-cast aluminum alloys (such as ADC12 or A380). We utilize advanced pre-treatment techniques to overcome typical porosity and high silicon content challenges, ensuring consistent corrosion protection and a clean finish.
Large Profile Anodizing
Equipped to handle oversized aluminum extrusions, large panels, and bulky structural components. Our high-capacity anodizing tanks and specialized handling equipment ensure a uniform coating thickness and consistent quality across exceptionally large surface areas.
Premium Anodizing for Diverse Aluminum Alloys
As an all-around hardware manufacturer, we expertly process a vast array of metals. However, when it comes to anodizing, aluminum is the undisputed industry standard. Different aluminum grades react differently to the anodizing process. Our engineering team precisely controls the parameters for each specific alloy to guarantee flawless results.
| Series & Type | Primary Alloying Element | Key Characteristics | Typical Applications | Machinability & Anodizing Suitability |
| 1000 Series(Pure Aluminum) | Aluminum (>99%) | Exceptionally soft, superior electrical and thermal conductivity. | Specialized electrical components, chemical equipment. | Machining: Poor (too soft).Finishing: Excellent for standard anodizing. |
| 2000 Series(Aerospace Alloy) | Copper (Cu) | Extreme hardness, high strength (aerospace-grade), lower natural corrosion resistance. | Aircraft structures, high-stress mechanical parts. | Machining: Good.Finishing: Requires specialized surface treatments due to low corrosion resistance. |
| 3000 Series(Rust-Proof Alloy) | Manganese (Mn) | Excellent formability and workability, rust-proof. | Sheet metal fabrication, architectural panels, chemical equipment. | Machining: Moderate.Finishing: Good, accepts standard finishes well. |
| 4000 Series(Welding Alloy) | Silicon (Si) | High silicon content, significantly lower melting point. | Specialized welding wire, brazing applications, architectural panels. | Machining: Moderate.Finishing: Not typically anodized (turns dark gray/black). |
| 5000 Series(Marine Alloy) | Magnesium (Mg) | Exceptional corrosion resistance (especially seawater), highly weldable. | Marine applications, robust sheet metal parts, pressure vessels. | Machining: Fair to Good.Finishing: Excellent for clear and color anodizing. |
| 6000 Series(The All-Rounder) | Magnesium (Mg) & Silicon (Si) | Perfect balance of medium structural strength and excellent corrosion resistance. | General CNC machined hardware, automotive parts, architectural extrusions. | Machining: Excellent.Finishing: Flawless results for premium decorative and color anodizing. |
| 7000 Series(Super-Alloy) | Zinc (Zn) | Steel-like strength, highest strength of all aluminum alloys. | Highly stressed aerospace components, military equipment, sporting goods. | Machining: Good.Finishing: Excels in Hardcoat (Type III) anodizing for maximum wear resistance. |
| 8000 Series(Specialty Alloys) | Lithium (Li), Iron (Fe), etc. | Engineered for customized material properties (e.g., lighter weight, higher stiffness). | Cutting-edge industrial, specialized aerospace, foil products. | Machining: Varies by specific alloy.Finishing: Varies by specific alloy formulation. |

Yes, but we precisely account for it. Type II anodizing typically adds a minimal layer (around 0.0002" to 0.001"), rarely affecting standard tolerances. Type III Hardcoat creates a thicker layer where half penetrates the metal and half builds up. As an expert manufacturer, XML calculates this exact buildup during the initial CNC programming phase to ensure your final finished parts perfectly meet strict ±0.001mm tolerances.
The choice depends entirely on your component's application. If your priority is a vibrant, decorative appearance with standard corrosion resistance (e.g., consumer electronics or cosmetic trims), Type II is ideal. However, if your part will face extreme friction, harsh environments, or requires electrical insulation (e.g., aerospace structural parts or industrial machinery), the extreme durability of Type III Hardcoat is necessary.
Absolutely. While we offer a robust gallery of standard colors like Deep Black, Cobalt Blue, and Champagne Gold, we fully support custom aesthetic requirements. By providing us with a specific Pantone (PMS) code or a physical color sample, our surface finishing experts will precisely formulate the dye to match your exact brand identity with zero color discrepancy.
Not at all. As an all-around hardware processing manufacturer, XML provides a complete one-stop solution. We handle everything from raw material precision CNC machining to the final anodizing and surface finishing under one roof. This eliminates the delays, risks, and shipping costs of managing multiple vendors, ensuring a faster turnaround for your entire project.
