Aluminium Flat Bar 50mm x 18mm

Description

The 50mm x 18mm aluminium flat bar is a wide and robust extrusion manufactured from EN AW-6063 aluminium alloy in T6 temper. With its substantial 18 mm thickness, this profile delivers high mechanical strength and dimensional stability, making it well-suited for heavy-duty industrial and structural applications.

It is frequently used in machine platforms, custom brackets, tooling setups, and architectural load frames. The combination of wide surface area and deep profile enhances both load-bearing performance and ease of processing in CNC machining, milling, and drilling operations.

Trusted by engineers and production teams, our flat bars support consistent performance in structural and decorative applications.

➤ Minimum order quantity: 500 kg.
