Automotive Lightweight Aluminum Extrusion
Automotive Lightweight Aluminum Extrusion is an aluminum profile series developed for vehicle body structures, battery enclosures, chassis components and interior support frames where weight reduction and structural strength are required together. Produced through precision extrusion and CNC processing, the profile series maintains dimensional accuracy while achieving reduced mass compared with steel components of equivalent function. Shanghai Huishuo Aluminum Industry Technology Co Ltd operates three production bases in Shanghai, Anhui and Jiangsu covering approximately 30000 square meters, with over 16 years of experience in industrial aluminum profile customization and processing. The company provides one stop services including profile extrusion, mold development, CNC machining, surface treatment and frame assembly, supporting customers across automotive, new energy vehicle and transportation equipment industries. Automotive Lightweight Aluminum Extrusion is available in multiple alloy grades and cross section designs to match different structural load and weight targets.

Frequently Asked Questions
Which alloy grade should be selected for structural components
Alloy grade selection depends on the required strength to weight ratio and forming method. 6061 alloy is commonly selected for higher strength structural applications while 6063 alloy is suited to complex cross sections with moderate strength needs.
Can the extrusion be customized for specific vehicle designs
Custom mold development is available to produce cross sections matching specific structural and packaging requirements of a vehicle platform.
What surface treatment is recommended for underbody parts
Chromate conversion coating combined with additional protective coating is commonly used for underbody and exterior exposed components to improve corrosion resistance.
Is the profile compatible with welding assembly
The profile series supports welding as well as riveting bolting and adhesive bonding depending on the assembly method specified by the project design.
What testing or certification support is available
Material certification and dimensional inspection reports can be provided according to project specifications and applicable industry requirements.
