Aluminum 6005 vs 6463
Aluminum · grade comparison
Aluminum 6005 and 6463 are both aluminum grades, both multipurpose al. 6005 is the stronger of the two: yield strength 245 MPa (35.5 ksi) against 214 MPa (31 ksi) for 6463, about 14% more; tensile strength follows at 270 MPa (39.2 ksi) vs 240 MPa (34.8 ksi). 6005 is harder — 85 HB against 74 HB for 6463 — which matters for wear surfaces and threads. On the shop floor, 6463 sits in a lower cost tier (budget, $) than 6005 (standard, $$).
6005Choose it when strength drives the design, or when surface hardness matters.
6463Choose it when cost is the deciding factor.
6005 vs 6463: 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.
