Aluminum 5042-H19 vs 5042-H28

Aluminum · 5042 temper comparison

5042-H19 and 5042-H28 are two conditions of the same aluminum grade, 5042: H19 (strain hardened, extra hard) versus H28 (strain hardened and partially annealed, full hard). The chemistry is identical, so every difference below comes from the condition. 5042-H19 is the stronger of the two: yield strength 331 MPa (48 ksi) against 305 MPa (44.2 ksi) for 5042-H28, about 9% more; tensile strength follows at 359 MPa (52.1 ksi) vs 340 MPa (49.3 ksi). In exchange, 5042-H28 is the more ductile: elongation 6% versus 4% for 5042-H19, and 5042-H19 is harder (100 HB vs 94 HB). 5042-H28 runs hotter in service (80°C vs 65°C continuous).

5042-H19Choose it when strength drives the design.

5042-H28Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
