Aluminum 8030-H14 vs 8030-O

Aluminum · 8030 temper comparison

8030-H14 and 8030-O are two conditions of the same aluminum grade, 8030: H14 (strain hardened, half hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 8030-H14 is the stronger of the two: yield strength 105 MPa (15.2 ksi) against 35 MPa (5.08 ksi) for 8030-O, about 3.0 times as much; tensile strength follows at 128 MPa (18.6 ksi) vs 85 MPa (12.3 ksi). In exchange, 8030-O is the more ductile: elongation 25% versus 8% for 8030-H14, and 8030-H14 is harder (35 HB vs 23 HB). 8030-O runs hotter in service (150°C vs 120°C continuous). On the shop floor, 8030-H14 machines more easily (fair vs poor).

8030-H14Choose it when strength drives the design, or when the part is machined in volume.

8030-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
