Aluminum ACP 5080 vs MoldMAX Aluminum

Aluminum · grade comparison

Aluminum ACP 5080 and MoldMAX Aluminum are both aluminum grades, both mold quality al. MoldMAX Aluminum is the stronger of the two: yield strength 495 MPa (71.8 ksi) against 110 MPa (16 ksi) for ACP 5080, about 4.5 times as much; tensile strength follows at 565 MPa (81.9 ksi) vs 172 MPa (24.9 ksi). MoldMAX Aluminum is the more ductile: elongation 8% versus 3% for ACP 5080, and MoldMAX Aluminum is harder (150 HB vs 65 HB). ACP 5080 runs hotter in service (150°C vs 120°C continuous). On the shop floor, ACP 5080 machines more easily (excellent vs very good), ACP 5080 welds better (fair vs poor), and ACP 5080 sits in a lower cost tier (standard, $$) than MoldMAX Aluminum (premium, $$$).
