Typical materials: AA 6063 and other grades of aluminum

AA 6063 is also referred to as an architectural alloy and is used in complex extrusions. As the most commonly used aluminum alloy, it is highly resistant to corrosion, weldable, can be easily anodized, and has a very good surface finish.

Anodizing aluminum increases its corrosion resistance and improves adhesion and lubrication.

AA 6063 is mostly used in:

• Enclosures
• Window frames
• Extrusions
• Fittings
• Doors
• Irrigation

Material composition:

• 0.6% Silicon
• 0.9% Magnesium
• 0.35% Iron
• 0.10% Copper
• 0.10% Manganese
• 0.10% Chromium
• 0.10% Zinc
• 0.10% Titanium
• Remainder Aluminum

Tensile strength: 145 to 186 Mpa (21 to 27 ksi)

Melting temperature: 615℃ (1,139 ℉)

Common MOQ: 100 to 10,000 pcs

Common or standardized parts generally have higher MOQ. Most Chinese manufacturers are flexible about MOQs but buyers are advised to be reasonable about the numbers.

Manufacturing methods: Extrusion and stamping

Anodized aluminum gives the metal surface a durable, decorative, and corrosion-resistant aluminum oxide finish. Our manufacturers use AA 6063 for intricate extrusions. Extrusion helps create complex cross-sections with an excellent surface finish. Whatever your requirement, our Chinese manufacturers would be able to manufacture products matching your exact specification. The process of extrusion also increases the strength of the metal.

We focus on precision and make sure that products are manufactured according to your design and specifications. All manufactured components come with a 125 micro finish, but a higher finish is achievable.

Manufacturing cluster area: Ningbo

Ningbo is a port city in the Zhejiang province of East China. It is one of the major economic hubs of China. The major industries in Ningbo are textiles, garments, home electric appliances, stationery, plastic machines, auto parts, and high-end mold.

There are over 3,000 home electric appliance manufacturers and nearly 10,000 factories that produce electrical appliance parts and accessories. The annual turnover of the home electric appliance industry in Ningbo accounts for 30% of the entire industry in China.

Ningbo is a significant auto parts production center in China, with over 2,300 manufacturers. The production value of the auto parts industry in Ningbo accounts for nearly 3.2% of China.

Application: Aesthetics, construction, vertical farming systems, and modular storage systems

Anodized aluminum extrusions are used across all business segments. The products manufactured with this method are attractive, highly durable enclosures, roofs, exteriors, ceilings, curtain walls, and floors. Most commercial buildings across the world use aluminum in staircases, lobbies, and elevators. Aluminum extrusions are extensively used in construction and architecture because they can handle high loads despite being lightweight.

Common issues: Dimensional control, surface finish, and color

Our Chinese manufacturers deploy rigorous in-process quality checks to make sure that products are manufactured exactly as per your specifications. This includes getting the dimensions right, making sure the best quality material is used, and the surfaces are accurate and polished with no edges or burrs.

Quality Control

Finished products go through the visual inspection queue to make sure they meet the quality standards. They also undergo CMM inspection to test the accuracy of the manufactured components.
