Aluminum profile 20×20 T-slot black

Product Description :

The Black Aluminum Profile 20×20 T-Slot Groove 6 is a lightweight yet strong extrusion designed for 3D printers, CNC machines, robotics, enclosures, and modular DIY projects. With its 20x20mm cross-section and 6mm slot width, it ensures compatibility with standard M5 fasteners, T-nuts, and T-slot accessories, making assembly both easy and reliable.

Made from EN-AW 6063 aluminum alloy (EN 515 | T66), this profile delivers excellent strength, rigidity, and durability. It offers a yield strength of ≥200 N/mm², tensile strength of ≥245 N/mm², and hardness of ≥80 HB. The 5.5mm core bore is suitable for M5 threading, allowing strong and secure connections in machine frames and structural builds.

Weighing just 0.439kg per meter, the extrusion is lightweight yet provides reliable rigidity. Moreover, the T-slot geometry allows easy integration with motion and fastening components. The black anodized surface (E6Ev1, 10–15µm) not only improves corrosion resistance but also gives the profile a sleek, professional look suitable for both industrial and consumer projects.

With a useful length of 6000mm (±10mm), this extrusion is ideal for both large machine assemblies and compact custom projects. Its combination of light weight, strength, and professional black finish makes it one of the most popular choices for modular framing systems.
