Description

The 19.9mm aluminium round bar is a precision-engineered solid rod produced from EN AW-6063 aluminium alloy in T6 temper. Just under the 20mm threshold, this profile offers excellent balance between strength, machinability, and weight, making it ideal for industrial applications that require both robustness and dimensional accuracy.

Typical uses include drive shafts, pivot pins, load-bearing spacers, and structural connectors used in mechanical assemblies, automation systems, and equipment fabrication. Its corrosion resistance and clean mill finish make it suitable for both indoor and outdoor environments.

Supplied in 6-metre standard lengths, this bar can be customised with anodised or powder-coated finishes upon request. Tailored lengths and cut-to-size services are available for large orders or OEM-specific projects.

We supply customers with scalable aluminium bar solutions, ensuring consistent quality and efficient worldwide delivery.

➤ Minimum order quantity: 500 kg.

➤ Delivery available worldwide via land, sea, or air freight.
