Aluminium Round Bar 70mm
Description
The 70mm aluminium round bar is a heavy-gauge solid rod manufactured from EN AW-6063 aluminium alloy in T6 temper. With its robust diameter and excellent strength-to-weight ratio, it is ideal for large-scale structural and mechanical applications where reliability and machinability are essential.
This profile is commonly used in the fabrication of industrial shafts, load-bearing pins, mechanical supports, and large custom-machined components across sectors such as heavy equipment manufacturing, transportation systems, and structural engineering. Its corrosion resistance and uniform surface make it suitable for further processing including CNC machining, anodising, and powder coating.
Each bar is supplied in 6-metre standard lengths with a smooth mill finish. Optional surface treatments and custom-cutting services are available to accommodate specific project requirements and production volumes.
Produced to tight tolerances, the 70mm round bar ensures stable, high-performance results in demanding industrial environments.
➤ Minimum order quantity: 500 kg.
➤ Delivery available worldwide via land, sea, or air freight.
