Aluminum 5050 vs 5454

Aluminum · grade comparison

Aluminum 5050 and 5454 are both aluminum grades. 5454 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 145 MPa (21 ksi) for 5050, about 41% more; tensile strength follows at 275 MPa (39.9 ksi) vs 170 MPa (24.7 ksi). 5454 is the more ductile: elongation 10% versus 9% for 5050, and 5454 is harder (73 HB vs 46 HB). 5050 conducts heat better (191 W/m·K vs 134 W/m·K). On the shop floor, 5454 machines more easily (good vs fair).

5454Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

5050 vs 5454 — frequently asked

Is 5454 stronger than 5050?

Yes. 5454 has a typical yield strength of 205 MPa (29.7 ksi) against 145 MPa (21 ksi) for 5050 — about 41% more. Tensile strength is 275 MPa (39.9 ksi) vs 170 MPa (24.7 ksi).

Which is cheaper, 5050 or 5454?

Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, 5050 or 5454?

5454. Its machinability rates good (55/100) against fair (40/100) for 5050; for welding the order is 5454 first (excellent, 90/100) then 5050 (excellent, 85/100).
