Aluminum ZL102 vs ZL116

Aluminum · grade comparison

Aluminum ZL102 and ZL116 are both aluminum grades. ZL116 is the stronger of the two: yield strength 255 MPa (37 ksi) against 80 MPa (11.6 ksi) for ZL102, about 3.2 times as much; tensile strength follows at 335 MPa (48.6 ksi) vs 170 MPa (24.7 ksi). In exchange, ZL102 is the more ductile: elongation 5% versus 4% for ZL116, and ZL116 is harder (90 HB vs 55 HB). ZL116 conducts electricity better (38 % IACS vs 31 % IACS). On the shop floor, ZL116 machines more easily (good vs fair) and ZL102 sits in a lower cost tier (budget, $) than ZL116 (standard, $$).

ZL102Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.

ZL116Choose it when strength drives the design, or when the part is machined in volume.
