Quick Answer for procurement

2011 aluminum (UNS A92011 / EN AW-2011 / AlCu6BiPb) is the best free-machining aluminum alloy, with 5.0–6.0% Cu plus free-cutting Lead & Bismuth (0.20–0.60% each), density 2.82 g/cm³, tensile 310–380 MPa (T3/T8). It delivers the highest machinability of any aluminum grade — small brittle chips, excellent finish and long tool life — for high-volume CNC turned and screw-machine parts. It is not fusion-weldable (Pb/Bi cause cracking/porosity). HXM stocks tube in T3/T4/T6/T8, lead time 12–30 days, MOQ 100 kg stock / 500 kg custom, quote within 24 h.

Why specify 2011 aluminum tube?

Best machinability of all aluminum alloys: Pb + Bi form short, brittle chips — faster feeds, better finish, longer tool life.
Excellent surface finish: ideal for precision turned components and screw-machine products.
Good strength-to-weight: 310–380 MPa tensile at 1/3 steel weight.
Stable, repeatable dimensions: great for high-volume automatic machining.
Documented & certified: ASTM B211/B221, EN 573/755, EN 10204 3.1 MTC.

2011 is the global standard for free-machining aluminum used in connectors, fasteners, fittings, valve bodies and precision instrument parts where machinability and finish dominate over corrosion resistance.

Where 2011 tube is used

Typical uses: screw-machine & CNC-turned components · connectors, terminals & contacts · precision nuts, bolts & fasteners (non-structural) · valve bodies & fittings · pistons & spacers · instrument & electronics hardware · camera & optical parts · automatic-lathe products. 2011 is chosen where high-volume machining speed and surface finish matter most; for welded assemblies use 6061, for higher strength use 2024. Note: 2011 is not for food contact or potable water (Pb/Bi).

Buyer pain points — and how HXM solves each

Pain #1

6061 / 7075 machine slowly and give poor chip control on auto-lathes.

HXM solution

2011 free-machining bar/rod runs faster with short brittle chips and superior finish — the right alloy for high-volume turned parts.

Pain #2

Assumed weldable like 6061 → cracking — 2011 is not fusion-weldable.

HXM solution

We flag up-front: 2011 (Pb/Bi) is for machined/fastened parts. For welded structures we supply 6061/6082. Welding guide →

Pain #3

Need a food/ROHS-compliant part — 2011 contains Lead & Bismuth.

HXM solution

We advise a lead-free alternative (e.g. 6023 / 6262) for food or EU ROHS use; 2011 is for general industrial precision parts.

Pain #4

Long lead from western mills — 90+ days on free-machining stock.

HXM solution

2011 T3/T8 stock across forms; 12–30 day lead, cut-to-size to your drawing.

Pain #5

No material certs — need EN 10204 3.1 for machined parts.

HXM solution

Full EN 10204 3.1 + AS9100D mill cert per lot. Machining guide →

Frequently asked questions (2011 aluminum tube)

Is 2011 aluminum weldable?

No — 2011 contains free-machining Lead and Bismuth which cause hot-cracking and porosity in fusion welding, and it is not recommended for brazing either. Join by mechanical fastening or adhesives. For welded assemblies use 6061/6082. It is supplied as machined/turned parts or stock, not welding wire.

Why is 2011 the best machining aluminum alloy?

The added Lead (0.20–0.60%) and Bismuth (0.20–0.60%) form a dispersed, low-melting phase that breaks chips into small brittle pieces, reduces built-up edge and gives excellent surface finish and long tool life — the highest machinability rating of any aluminum grade, ideal for screw machines and CNC turning.

Is 2011 suitable for food contact or ROHS?

No — the Lead/Bismuth content means 2011 is not for food contact, potable water or EU ROHS-restricted applications. For those, ask for a lead-free free-machining alternative such as 6023 or 6262.

What sizes and tempers can you supply?

Across forms: bar/rod 3–300 mm dia, tube OD 6–300 mm, wire 0.8–30 mm, strip/coil 0.2–6 mm — all cut-to-size. Tempers O, T3, T4, T6, T8. Stock and custom on request.

How does 2011 corrosion resistance compare?

Lower than 6061/6082 because of Pb/Bi; for corrosive service choose 6061/6082 or apply anodizing/coating. 2011 is best where machinability and finish dominate, not in marine/corrosive environments.

Do you provide material certification?

Yes — EN 10204 3.1 MTC + AS9100D mill cert every lot, with spectro analysis on request.
