Aluminum 6262A
AA 6262A · EN AlMg1SiSn
6262A (AlMg1SiSn) is a free-machining Al-Mg-Si bar alloy in which tin replaces the lead of 6262 as the chip-breaking phase, so parts meet lead-restriction requirements.

Compare all 8 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Annealed | Softest condition, used only as a processing state for heavy cold working or re-drawing before heat treatment. | 60 | 130 | 25 | 32 HB | 47 % IACS |
Solution heat treated and naturally aged | Occasional intermediate condition when parts must be bent, staked or swaged before final artificial aging. | 130 | 240 | 20 | 65 HB | 40 % IACS |
T6Default Solution heat treated and artificially aged | Standard stocked rod/bar condition: best balance of strength, ductility and free-machining behaviour for general screw-machined parts. | 275 | 310 | 12 | 95 HB | 43 % IACS |
T6, stress relieved by stretching | Pick when tight dimensional stability after heavy machining matters; strength as T6 but with low residual stress. | 280 | 310 | 11 | 95 HB | 43 % IACS |
T6, stress relieved by stretching, minor straightening | Extruded/drawn bar supplied straight and low-stress for automatic-lathe feeding of long parts. | 280 | 310 | 11 | 95 HB | 43 % IACS |
Solution heat treated, cold worked and artificially aged | Choose for higher strength and better surface finish/size tolerance than T6 while keeping useful ductility. | 360 | 380 | 10 | 115 HB | 44 % IACS |
T8 with stress-relief stretching and minor straightening | T8 strength with controlled straightness and low residual stress for precision turned components. | 360 | 380 | 10 | 115 HB | 44 % IACS |
Solution heat treated, artificially aged and cold worked | Highest strength and hardness plus the best chip control and surface finish; use for hard, close-tolerance drawn bar on multi-spindle machines. | 380 | 400 | 10 | 120 HB | 44 % IACS |
What is 6262A?
6262A (AlMg1SiSn) is a free-machining Al-Mg-Si bar alloy in which tin replaces the lead of 6262 as the chip-breaking phase, so parts meet lead-restriction requirements. Tempers T6, T651, T6511, T8, T8511 and T9 give 275 MPa yield, 310 MPa tensile, 12 % elongation and a machinability rating of 88 for high-volume turned work. Welding is the main limit: the low-melting tin phase promotes hot cracking, so weldability rates 35, and formability (40) and the 150 °C service ceiling also restrict use. Choose 6061 where joints must be welded. 6262A has a density of 2.71 g/cm³ (0.0979 lb/in³), heavier than 51% of aluminum grades. It melts at 582°C (1,080 °F). 6262A has a yield strength of 275 MPa (39.9 ksi) and a tensile strength of 310 MPa (45 ksi) — stronger than 70% of aluminum grades. Elongation at break is 12% and the elastic modulus is 69.5 GPa (10.1 Msi).

Working with 6262A
Is 6262A easy to machine?
Excellent free-cutting behaviour: the soft Sn phase breaks chips so parts run at high feeds on CNC and multi-spindle lathes with polished-flute carbide tools; T8/T9 give the best finish and closest tolerances.
Can 6262A be welded?
Not recommended for structural welding — the low-melting Sn phase promotes hot cracking and weld porosity; use mechanical joining or, if welding is unavoidable, qualify GTAW with 4043/5356 filler on non-critical joints.
Can 6262A be formed, bent or molded?
Cold formability is limited in T6/T8/T9 (generous bend radii, avoid heavy staking); do severe forming in O or T4 and age afterwards, and keep hot-working temperatures below about 400 °C to avoid Sn-related hot shortness.

Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on 6262A?
Clear and hard anodizing respond well and give good wear/corrosion protection; bright decorative anodizing or high-polish work can show faint speckle from Sn particles, and electroless nickel or chromate conversion are good alternatives.

6262A — frequently asked
What is 6262A used for?
6262A is typically used for precision machined fittings, fasteners and roHS-compliant free-machining parts. In short: lead-free free-machining 6000 series; screw-machine bar grade; direct 6262 replacement.
What is the yield strength of 6262A?
6262A has a typical yield strength of 275 MPa (39.9 ksi) and a tensile strength of 310 MPa (45 ksi) — stronger than 70% of aluminum grades. Strength varies by condition: see the 8 listed tempers.
Is 6262A easy to machine?
Yes — machinability is rated excellent (88/100, better than 96% of aluminum grades). Excellent free-cutting behaviour: the soft Sn phase breaks chips so parts run at high feeds on CNC and multi-spindle lathes with polished-flute carbide tools; T8/T9 give the best finish and closest tolerances.
Can 6262A be welded?
With care — weldability is rated fair (35/100). Not recommended for structural welding — the low-melting Sn phase promotes hot cracking and weld porosity; use mechanical joining or, if welding is unavoidable, qualify GTAW with 4043/5356 filler on non-critical joints.
What surface finishes work on 6262A?
Clear and hard anodizing respond well and give good wear/corrosion protection; bright decorative anodizing or high-polish work can show faint speckle from Sn particles, and electroless nickel or chromate conversion are good alternatives.
Can 6262A be formed, bent or molded?
Cold formability is limited in T6/T8/T9 (generous bend radii, avoid heavy staking); do severe forming in O or T4 and age afterwards, and keep hot-working temperatures below about 400 °C to avoid Sn-related hot shortness.
What is the maximum service temperature of 6262A?
6262A is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 6262A-T6 and 6262A-O?
T6 is the default condition — standard stocked rod/bar condition: best balance of strength, ductility and free-machining behaviour for general screw-machined parts. O: softest condition, used only as a processing state for heavy cold working or re-drawing before heat treatment. Yield strength is 275 MPa in T6 versus 60 MPa in O.
