Natural anodising (frequently designated as clear anodising or Type II anodising under MIL-A-8625 specifications) is an electrochemical conversion process that thickens the natural oxide layer on aluminum parts. Unlike paint or plating, which are applied onto the metal surface, natural anodising converts the base aluminum ($Al$) into a highly ordered, porous structure of aluminum oxide ($Al_2O_3$) that is completely integrated with the underlying substrate.
During the process, the aluminum components serve as the anode in an acid electrolyte bath (typically sulfuric acid, $H_2SO_4$, at a concentration of 15% to 20% by weight). When electrical current passes through the bath, water molecules split, yielding oxygen ions that migrate to the aluminum surface:
2Al + 3H₂O → Al₂O₃ + 6H⁺ + 6e⁻
The resulting clear oxide layer provides exceptional hardness (250–350 HV), corrosion resistance, and electrical insulation, while preserving the metal's natural aesthetic texture and metallic reflectivity.
Different aluminum alloys respond differently to the electrochemical clear anodising process. Selecting the correct grade is critical to achieving uniform color, gloss, and performance.
| Alloy Series | Composition Highlights | Natural Anodising Suitability | Visual Aspect & Key Applications |
|---|---|---|---|
| 5xxx Series (e.g., 5052) | Magnesium ($Mg$) rich | Excellent | Clear, high-gloss finish. Exceptionally high corrosion resistance; ideal for marine and chemical environments. |
| 6xxx Series (e.g., 6061, 6063) | Silicon & Magnesium ($Si, Mg$) | Outstanding (Industry Standard) | Perfect clear satin or bright appearance. Excellent response to pre-etching. Used in automotive structural components and CNC enclosures. |
| 7xxx Series (e.g., 7075) | Zinc ($Zn$) rich | Moderate | Yields a slightly darker, gold-olive or grey hue. High mechanical strength. Used extensively in aerospace structures. |
| Cast Alloys (e.g., A380) | High Silicon ($Si$) content | Poor to Fair | Silvery-grey to dark grey finish due to elemental silicon segregation. Best suited for protection rather than aesthetics. |
Founded in 1996 as an owner-managed SME family enterprise, XinYe Metal Works has grown into a highly reliable and vertically integrated provider of precision metal fabrication services. Located in the Ningbo Jiangbei Industrial Zone, our facility is within 3 hours of the Shanghai international transportation hub via high-speed rail networks, positioning us perfectly for efficient international logistics.
Our manufacturing campus spans 16,000 square meters of modern production floors, supplemented by 11,000 square meters of designated construction expansion area. We employ 130 dedicated personnel, including 80 highly skilled production technicians and 50 experts specialized in product development, engineering, quality assurance, and global supply chain management.
XinYe provides a complete manufacturing solution: from hot forging and stamping to precision multi-axis CNC machining, deep drawing, lost wax casting, and automated anodising and electrochemical polishing (E-polish) surface treatments.
From raw material forming to precision surface finishes, we utilize high-precision machinery imported from Japan and Europe to achieve tight tolerances.
Large-scale mechanical presses (300T to 1000T) paired with induction heaters for consistent heating and high-density aluminum alloy structural consolidation.
Equipped with 4-axis control centers for high-precision subtractive machining, maintaining tight clearances on anodised components.
An array of metrological tools, including CMM coordinate testing and spectrometers, verifying that physical dimensions and materials match specifications.
Watch our automated TIPAS MACHINE h65TMY in action, ensuring precision output for complex components.
Our natural anodised aluminum and forged components are widely utilized in critical industries across Europe, North America, and international markets.
Flame sensors, explosion-proof toxic gas detectors, mining sensor housings, and fire prevention enclosures. The non-sparking properties of anodised aluminum are essential for oil, gas, and hazardous environments.
Turbine inlets, transmission parts, hinge brackets, and aviation fuel hydrant pit box enclosure kits. The natural anodised coating prevents stress corrosion cracking under atmospheric pressures.
High-stress transmission components, engine brackets, and E-Bike structural parts (connectors, frame tubes, brake levers) requiring optimal strength-to-weight ratios and salt-spray resistance.
Tabletop cooking stoves, commercial cream whippers, and food processing fixtures. Anodised alumina surfaces are non-reactive, non-toxic, and fully compliant with sanitary contact regulations.
At XinYe, quality control is integrated into every phase of production. We operate under a strict quality management system, maintaining traceability from incoming raw ingots to final surface-treated assemblies.
With our clients' guidance and engineering feedback, we have established robust testing routines. Our material inspection utilizes a chemical spectrum analyzer to verify alloy composition, while our dimensional controls employ advanced CMM systems capable of sub-micron precision measurement.
Our facility holds certified registrations for both ISO 9001:2015 (Quality Management) and SA8000 (Social Accountability), highlighting our commitment to reliable manufacturing practices and ethical labor standards.
XinYe's manufacturing ecosystem leverages the industrial clustering of Ningbo, a major hub for non-ferrous metallurgy, mold design, and surface engineering. This geographic proximity to domestic raw metal producers minimizes logistic costs and shields our operations from supply chain delays.
Our standard operating schedule runs 16 hours a day, 6 days a week. In response to fluctuating seasonal demand or critical production spikes, we can transition to a 24/7 continuous operation mode within 30 days. Our on-site land resources also allow for seamless physical expansion as client demand grows.
By integrating casting, forging, stamping, precision machining, and electrochemical anodising under one roof, we eliminate multiple intermediate transport costs, reduce handling risks, and ensure a single point of quality responsibility.
Our operations are guided by trust, accountability, and a commitment to professional growth, aligning with our SA8000 social standard framework.
Building long-term client relationships through transparent communication, honest pricing, and consistent production schedules.
Maintaining strict quality standards from raw material checks to product delivery, and ensuring a safe, sustainable working environment.
Driving manufacturing excellence through investment in employee training, advanced machinery, and continuous process optimization.
Our structured engineering and manufacturing process ensures consistent quality control from raw material receipt through to final delivery.
Submit drawings, technical tolerances, and specification requirements for engineering review.
Prototypes are manufactured, measured, and provided with full dimensional test reports.
We evaluate customer feedback to implement adjustments prior to bulk manufacturing.
Standard production begins under the oversight of in-process quality control gates.
One-year warranty coverage and dedicated technical support for any inquiries.
In addition to manufacturing raw components, we operate a dedicated assembly workshop. This allows us to deliver fully assembled mechanical structures directly to our customers' supply lines, optimizing overall supply chain efficiency.
We carefully inspect all raw materials before production to ensure they meet engineering specifications. Finished products undergo a comprehensive final check, with complete quality documentation provided for every order.
