What is 6010-O?
6010-O is 6010 in the O temper — pick when maximum drawability or deep bending is needed and strength is developed later by solution treatment plus aging. 6010-O has a yield strength of 70 MPa (10.2 ksi) and a tensile strength of 140 MPa (20.3 ksi) — weaker than 92% of aluminum grades. Elongation at break is 28% and the elastic modulus is 69 GPa (10 Msi). 6010-O has a density of 2.71 g/cm³ (0.0979 lb/in³), heavier than 51% of aluminum grades. It melts at 585°C (1,085 °F).

Working with 6010-O
Is 6010 easy to machine?
Machines like other 6xxx but is gummy in T4 — use polished-flute carbide, high surface speed, sharp positive rake and flood coolant; aged (T6) material gives cleaner chips and better finish.
Can 6010 be welded?
Excellent for resistance spot, laser and MIG joining of body panels; for fusion welds use 4043/4047 filler to limit hot cracking from the Cu content and expect HAZ softening in T6.
Can 6010 be formed, bent or molded?
Designed for room-temperature stamping, deep drawing and flat hemming in T4; keep the natural-aging clock in mind (formability drifts with time at RT) and expect springback higher than mild steel.
What surface finishes work on 6010?
Normally e-coated/painted as body sheet; chromate-free conversion coatings and adhesive bonding work well, while clear decorative anodizing is dull/dark because of copper — use dyed or hard anodize instead.

6010-O — frequently asked
What is 6010-O used for?
6010-O is typically used for hood panels, automotive body sheet, door and closure inner panels, deck-lid and tailgate skins, fenders and roof panels and stamped structural sheet reinforcements. In short: auto closure panel alloy.
What is the yield strength of 6010-O?
6010-O has a typical yield strength of 70 MPa (10.2 ksi) and a tensile strength of 140 MPa (20.3 ksi) — weaker than 92% of aluminum grades. Strength varies by condition: see the 3 listed tempers.
Is 6010-O easy to machine?
Reasonably — machinability is rated fair (45/100, worse than 72% of aluminum grades). Machines like other 6xxx but is gummy in T4 — use polished-flute carbide, high surface speed, sharp positive rake and flood coolant; aged (T6) material gives cleaner chips and better finish.
Can 6010-O be welded?
Yes — weldability is rated good (60/100). Excellent for resistance spot, laser and MIG joining of body panels; for fusion welds use 4043/4047 filler to limit hot cracking from the Cu content and expect HAZ softening in T6.
What surface finishes work on 6010-O?

What is the maximum service temperature of 6010-O?
6010-O is rated for continuous use to about 120°C (248 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
