Precision Ground Bar
Next Generation Metals supplies precision machine and swiss straightener shops with machining bar with absolute dimensional consistency.
Our AccRound Sales Staff is a one-stop raw material and grinding source that can lower your cost and lead time.
Next Generation Metals AccuRound precision ground bar can be counted on for consistent diameter tolerance, roundness and straightness.
We source material from the highest quality mills and our grinding will give you superior straightness and tolerance throughout the length of your bar. We can hold tolerances of +/-.0001 on any 12′ length bar with +/-.00005 roundness.
We supply domestic and foreign material from Europe. We stock DFARS material as well. We stock oversizes for our customers with uncommon requirements.
We also can supply you with heat treating, straightening, bar end chamfering and saw cutting.

2011 Aluminum Alcoa
Alcoa 2011, a cold finished aluminum wrought product, is suggested for applications requiring high productivity and excellent machinability. It is the most free-machining of all aluminum alloys due to the additions of lead and bismuth. Typical applications include auto fuel system componentry, clock parts, gears, machine parts, pipe stems, TV fittings, camera parts, meter shafts, ordnance, industrial connectors, and speedometer components.
The -T3 temper is the choice when high productivity at moderate strength is key. The -T451 temper offers excellent deep hole drilling characteristics at a lower strength level. When higher strength is required, -T8 temper is the preferred choice.
Alcoa 2011 offers excellent machinability with high productivity when machined using single-point or multi-spindle carbide tools on screw machines. The use of a chip breaker is not necessary in most cases. Being the most free-machining of all aluminum screw machine stock alloys, Toolrite 2011® is rated “A” giving very small broken chips and excellent surface finish on the final machined part. Machined finishes in the range of 5 to 10 microinches have been obtained in some applications using carbide tools.
The properties listed in this Alloy Data Sheet represent the best current information for this alloy. In each specific application, the user is expected to evaluate and test the alloy, temper and finishing method. Consult the Material Safety Data Sheet (MSDS) for proper safety and handling precautions when using Toolrite 2011® alloy.
