High-Strength Rectangular Aluminum Tube for Automobile

Engineering Lightweight Automotive Solutions

In the modern automotive industry, weight reduction is paramount for fuel efficiency and EV range extension. Our Rectangular Aluminum Tube for Automobile is engineered to meet these rigorous demands. Utilizing advanced extrusion processes and high-frequency welding technologies, we deliver profiles that offer an exceptional strength-to-weight ratio.

Unlike standard stock shapes, our manufacturing capability allows for custom and special-shaped aluminum profiles. Whether you require structural integrity for chassis components or high thermal conductivity for heat exchangers, our tubes are precision-crafted to ensure exact fitment, reducing secondary machining costs and streamlining your vehicle assembly line.

Surface Treatment Options: Aesthetics Meets Durability

Automotive components face harsh environmental conditions, from road salts to extreme UV exposure. We provide comprehensive surface treatments that enhance both the longevity and visual appeal of our rectangular tubes.

Anodized Finishes

Our Anodized Rectangular Aluminum Tubes undergo an electrochemical process that thickens the natural oxide layer. This results in a surface harder than raw aluminum and highly resistant to corrosion.

• Available Colors: Champagne, Black, Silver, Gold.

• Textures: Silver Sand, Matt, Brushed, Polished.

• Benefit: Ideal for visible interior trim or exterior roof rails where a premium metallic look is required without peeling or chipping.

Powder-Coated Finishes

For parts requiring specific color matching and extreme durability, our Powder-Coated Aluminum Tubes create a thick, uniform protective layer.

• Color Palette: White, Matt Black, Metallic Gray, Light Gray, Dark Gray.

• Benefit: Superior resistance to scratching, fading, and chipping compared to liquid paint. This is essential for under-carriage parts or exposed frame elements.

Key Applications in the Automotive Sector

Our rectangular aluminum tubing is versatile, serving various subsystems within a vehicle:

1. Thermal Management Systems:
Utilizing 3003 and 3103 alloys, our tubes are used in radiators, condensers, and intercoolers. The high-frequency welding ensures leak-proof performance, critical for fluid transport in cooling systems.

2. Structural Components:
Using 6061-T6 and 6063-T5 alloys, we supply tubes for bumper beams, chassis reinforcements, and instrument panel beams. The extrusion process allows for complex internal webs that increase stiffness without adding weight.

3. Decorative & Functional Trim:
Anodized and polished tubes are used for luggage racks, side steps, and interior aesthetic lines, combining luxury visuals with functional load-bearing capacity.
