3/4 Aluminum Hex Tube 18in

The 3/4 Aluminum Hex Tube 18in from ALLSTAR PERFORMANCE is a precision structural component engineered for custom automotive fabrication, frame repairs, and performance chassis work. Whether you're building a roll cage, constructing custom suspension arms, or reinforcing a street rod frame, this hex tube delivers the lightweight strength that serious fabricators demand. At 18 inches long, it's sized for both prototype development and production welding applications where material consistency and dimensional accuracy matter.

Manufactured from aluminum alloy, the 3/4 Aluminum Hex Tube offers an exceptional strength-to-weight ratio compared to steel alternatives—a critical advantage in competition vehicles and high-performance builds where unsprung weight directly impacts handling. The hexagonal cross-section provides superior rigidity in bending and torsion while maintaining structural efficiency, making it ideal for load-bearing applications where traditional round tubing would require oversizing. The 1.45 × 1.25 inch profile dimensions are precision-drawn to tight tolerances, ensuring consistent fit-up during TIG or MIG welding and repeatability across multiple fabrication runs. At just 1.25 pounds, this 18-inch length minimizes chassis weight without compromising durability.

Professional fabricators, race car builders, and restoration shops trust ALLSTAR PERFORMANCE tube stock for A-arm construction, cage building, and custom suspension geometry work. This hex tube is compatible with both CNC plasma cutting and manual hacksaw cutting, accommodates standard orbital welding equipment, and finishes cleanly with minimal grinding. Installation requires basic metal fabrication skills—layout, cutting, fixture clamping, and full-penetration welds. For maximum performance in structural applications, verify material thickness and alloy specification against your specific load requirements before committing to your project.
