Aluminum 5050-H14 vs 5050-O

Aluminum · 5050 temper comparison

5050-H14 and 5050-O are two conditions of the same aluminum grade, 5050: H14 (strain hardened, half hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 5050-H14 is the stronger of the two: yield strength 165 MPa (23.9 ksi) against 55 MPa (7.98 ksi) for 5050-O, about 3.0 times as much; tensile strength follows at 195 MPa (28.3 ksi) vs 145 MPa (21 ksi). In exchange, 5050-O is the more ductile: elongation 24% versus 6% for 5050-H14, and 5050-H14 is harder (53 HB vs 36 HB). 5050-O runs hotter in service (200°C vs 120°C continuous). On the shop floor, 5050-H14 machines more easily (fair vs poor).

5050-H14Choose it when strength drives the design, or when the part is machined in volume.

5050-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
