Aluminum profile 20×20 T-slot silver

Product Description

This 20×20 aluminum profile slot 6 (light version) is designed for lightweight yet stable frame constructions. With a precise slot width of 6mm, it is compatible with standard M5 fasteners and accessories. The profile is anodized for durability and corrosion resistance, making it suitable for 3D printer frames, CNC machines, enclosures, and other DIY or industrial applications.

The EN-AW 6063 T66 aluminum alloy ensures excellent mechanical strength while keeping the weight low at only 0.439 kg/m. The profile provides a good balance between stiffness and lightweight design, making it ideal for compact builds.
