Aluminum 295.0 vs 356

Aluminum · grade comparison

Aluminum 295.0 and 356 are both aluminum grades. 356 is the stronger of the two: yield strength 186 MPa (27 ksi) against 165 MPa (23.9 ksi) for 295.0, about 13% more. 356 is harder — 80 HB against 75 HB for 295.0 — which matters for wear surfaces and threads. 356 is lighter (2.67 g/cm³ vs 2.81 g/cm³ for 295.0). On the shop floor, 356 welds better (very good vs poor) and 356 sits in a lower cost tier (budget, $) than 295.0 (standard, $$).

356Choose it when strength drives the design, or when surface hardness matters.
