Aluminum 4032 vs 4147

Aluminum · grade comparison

Aluminum 4032 and 4147 are both aluminum grades. 4032 is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 60 MPa (8.7 ksi) for 4147, about 5.3 times as much; tensile strength follows at 380 MPa (55.1 ksi) vs 130 MPa (18.9 ksi). In exchange, 4147 is the more ductile: elongation 15% versus 9% for 4032, and 4032 is harder (120 HB vs 45 HB). 4032 is stiffer (79 GPa vs 71 GPa) and 4032 runs hotter in service (175°C vs 150°C continuous). On the shop floor, 4032 machines more easily (good vs poor), 4147 welds better (50 vs 40 out of 100), and 4032 sits in a lower cost tier (standard, $$) than 4147 (high, $$$$).

4032Choose it when strength drives the design, or when the part sees heat.

4147Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
