Aluminium Round Bar 21mm
Description
The 21mm aluminium round bar is a solid, precision-extruded profile manufactured from EN AW-6063 aluminium alloy in T6 temper. With its increased diameter and excellent strength-to-weight ratio, it is ideal for applications requiring both structural integrity and ease of machining.
Typical uses include custom machine parts, axle components, load-distributing pins, industrial fixtures, and fabrication elements in machinery and construction. The bar’s consistent geometry and surface quality make it suitable for processes like CNC machining, drilling, and turning.
Each bar is delivered in 6-metre standard lengths with mill finish. Optional surface treatments such as anodising or powder coating can be applied based on project requirements. Custom-cutting and non-standard lengths are available for high-volume orders.
We supply aluminium bars and profiles to manufacturers, fabricators, and industrial buyers, supporting their need for dependable material quality and scalable production.
➤ Minimum order quantity: 500 kg.
➤ Delivery available worldwide via land, sea, or air freight.
