Round aluminium bars Ø110-250 mm for turning and CNC machining
Round bars in this category are solid aluminium bars in EN AW-2017A T4 duralumin, supplied in 2000 mm lengths with diameters from Ø110 mm to Ø250 mm. They are semi-finished stock for turning, milling and CNC machining. The surface is raw and non-anodised. They suit professional workshops that make shafts, pins, bushings and machine components.
What you will find in this category
- Solid round bars Ø110, 115, 120 and 130 mm, 2000 mm long, weighing 53.22-74.34 kg per bar.
- Solid round bars Ø140, 150, 160 and 180 mm, 2000 mm long, weighing 86.20-142.50 kg per bar.
- Large-diameter solid round bars Ø200 and Ø250 mm, 2000 mm long, weighing 175.94-274.90 kg per bar.
- All sizes: alloy EN AW-2017A (AlCu4MgSi), T4 temper, raw surface, non-anodised.
How to choose
- Diameter: choose the size that covers the finished part with enough allowance for machining. Ten sizes are available, from Ø110 mm to Ø250 mm.
- Alloy and temper: all bars are 2017A T4, also listed as AlCu4MgSi, PA6 or 3.1325. The Ø120 mm bar is listed with a tensile strength of 380-430 MPa.
- Surface: bars are raw and non-anodised. Plan any finishing after machining to suit your project.
- Weight and length: every bar is 2000 mm long. Check the weight, for example 86.20 kg for Ø140 mm, before planning handling and cutting.
Typical applications
Duralumin 2017A T4 combines high mechanical strength with good machinability. These bars are used for turning large components such as shafts, pins and bushings. They also suit machine and structural parts made on conventional lathes, milling machines and CNC machining centres.
Frequently asked questions
Are the round bars anodised?
No. All bars have a raw, non-anodised surface, so you can carry out further finishing to suit your project.
What length are the bars?
All bars in this category are 2000 mm long. Diameters range from Ø110 mm to Ø250 mm.
Which alloy are the bars made from?
EN AW-2017A (AlCu4MgSi) in T4 temper, a duralumin alloy. It is also listed as PA6 or 3.1325 and is intended for CNC machining, turning and milling.
