Aluminum 6060 vs 6B02
Aluminum · grade comparison
Aluminum 6060 and 6B02 are both aluminum grades. 6B02 is the stronger of the two: yield strength 235 MPa (34.1 ksi) against 170 MPa (24.7 ksi) for 6060, about 38% more; tensile strength follows at 270 MPa (39.2 ksi) vs 215 MPa (31.2 ksi). 6B02 is harder — 95 HB against 75 HB for 6060 — which matters for wear surfaces and threads. 6060 conducts heat better (200 W/m·K vs 170 W/m·K). On the shop floor, 6060 welds better (excellent vs very good), 6060 forms better (good vs fair), and 6060 sits in a lower cost tier (budget, $) than 6B02 (standard, $$).
6060Choose it when it will be welded, or when cost is the deciding factor.
6B02Choose it when strength drives the design, or when surface hardness matters.
6060 vs 6B02: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all aluminum grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
