Aluminium Flat Bar 40mm x 6.8mm
Description
The 40mm x 6.8mm aluminium flat bar is a precision-engineered, heavy-duty extrusion profile made from EN AW-6063 aluminium alloy in T6 temper. Its unique combination of 40 mm width and 6.8 mm thickness offers outstanding rigidity, impact resistance, and dimensional precision—making it ideal for structural and mechanical systems requiring stable, machine-ready components.
This profile is widely used in base plates, machine brackets, industrial subframes, and fixture assemblies where minimal deflection and maximum strength are essential. Its near-7 mm thickness provides reliable performance under mechanical loads while maintaining ease of handling during fabrication.
Supplied with a clean mill finish, the profile supports a wide range of processes such as CNC milling, drilling, cutting, and surface finishing. Optional anodised or powder-coated finishes are available to enhance protection or meet visual and functional design criteria.
Each bar is supplied in 6-metre standard lengths. Tailored cut-to-size and finishing services are available upon request for production environments.
We supply aluminium flat bars to manufacturers, fabricators, and contractors seeking consistent quality and reliable supply for their operations.
➤ Minimum order quantity: 500 kg.
➤ Worldwide delivery via road, sea, or air freight.
