Explore our core engineering capabilities in metal component design and precision manufacturing
Natural anodization is not merely a surface finish; it is a controlled electrochemical modification of the aluminum alloy substrate itself. This process thickens the natural, microscopic oxide layer into a highly uniform, durable, and corrosion-resistant anodic coating. As a leading OEM Natural Anodized Aluminium Supplier and Factory, Ningbo Jiangbei XinYe Metal Works Co., Ltd. delivers custom components designed for severe operating conditions across marine, automotive, medical, and aerospace applications.
The anodization process at our facility involves placing the aluminum components in an acid electrolyte bath (principally sulfuric acid, H2SO4) and passing a direct current through the medium. The aluminum acts as the anode, releasing oxygen ions that react with the surface aluminum atoms to form aluminum oxide (Al2O3).
Depending on the alloy composition (e.g., 6061, 6063, 7075, or 5052), our metallurgical team monitors specific variables:
Founded in 1996 as a highly focused family business, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has developed into an owner-managed SME corporation recognized globally for precision metal components.

We provide full documentation for all export processes, including:
Quality is the baseline of our operations. We maintain traceability records for every stage from raw ingot chemistry to final surface verification.
Used to verify the alloy chemistry before forging or extrusion starts, ensuring raw material specs comply with ASTM or EN standards.
Coordinates dimensions of machined components are mapped in 3D to confirm that geometric tolerances match CAD drawings.
Optical dimensional measurement for small geometries and complex profiles without contacting the surface.
Secondary optical testing station for mass production quality runs and random assembly checks.
Checks surface profile roughness values (Ra) to ensure natural anodized finishes meet specification requirements.
Verifies structural capacity of finished mechanical components under physical loads.

A systematic workflow ensures traceability and dimensional compliance at every manufacturing stage
We review custom drawings, confirm specifications, and align tolerances.
We configure tooling and run prototype samples using CNC machining or casting setups.
Dimensional inspections are completed before shipping samples for validation.
We run production parts under process controls and complete surface treatments.
Parts are checked and packed in protective crating for shipping.
Our quality engineering process starts with verification of incoming materials. Handled internally by our laboratory, we inspect incoming billets for copper, zinc, magnesium, and silicon ratios to avoid cracking during subsequent forging and anodization stages.
In addition to component production and surface treatment, we maintain a dedicated assembly area. This allows us to supply complete mechanical assemblies, reducing shipping costs and supplier management overhead for our global customers.
