Typical materials: AA 6063 and various other grades of aluminum

6063 is the most commonly used aluminum alloy used for extrusion. It is an aluminum alloy containing some parts of silicon and magnesium. AA 6063 is heat treatable, weldable, and has excellent mechanical properties. Hence, the metal can be used to form complex shapes with very smooth surfaces. It has high corrosion resistance and can be easily anodized.

AA 6063 is mostly used in:

• Architecture
• Window frames
• Extrusions
• Shop fittings
• Doors
• Irrigation tubing

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: 500 to 10,000 pcs

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

Manufacturing methods: Extrusion

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 specifications. 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, located in the northeast Zhejiang province of China, is a major industrial hub in the country. The port of Ningbo-Zhoushan is one of the busiest in the world.

It is a major production base of home electric appliances in China.  The turnover of the industry in Ningbo accounts for nearly 30% of the entire home electric appliance industry of China. The city houses over 3,000 home electrical appliance manufacturers and 10,000 factories producing electrical appliances parts and accessories.

The sectors of textiles, garments, home electric appliances, stationery, plastic machines, auto parts, and high-end mold are thriving in Ningbo. The textile industry in the city accounts for 12% of the total industry output of the city.

Ningbo is a significant auto parts production center in China, with over 2,300 manufacturers. The city is also called the Stationery Capital of China, housing more than 800 stationery manufacturers. The mold industry is also very prominent in Ningbo with over 3,000 manufacturers.

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

Aluminum is a commonly used metal and is used in various domestic and commercial settings. Aluminum extrusions are extensively used in construction and architecture because they can handle high loads despite being lightweight. Elevator shafts, lighting fixtures, and stairwells also use aluminum fixtures.

Aluminum extrusions are also widely used in the automobile industry. Extruded aluminum has a high strength to weight ratio that makes it ideal for the automobile industry.

Common issues: Dimensional control, surface finish, structural integrity, 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.
