Aluminum 1050 vs 5025
Aluminum · grade comparison
Aluminum 1050 and 5025 are both aluminum grades, both corrosion resistant al. 5025 is the stronger of the two: yield strength 155 MPa (22.5 ksi) against 90 MPa (13.1 ksi) for 1050, about 72% more; tensile strength follows at 195 MPa (28.3 ksi) vs 110 MPa (16 ksi). 5025 is the more ductile: elongation 10% versus 5% for 1050, and 5025 is harder (55 HB vs 30 HB). 1050 runs hotter in service (150°C vs 120°C continuous) and 1050 conducts heat better (229 W/m·K vs 185 W/m·K).
1050Choose it when the part sees heat.
5025Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1050 vs 5025: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all aluminum grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

1050 vs 5025 — frequently asked
Is 5025 stronger than 1050?
Yes. 5025 has a typical yield strength of 155 MPa (22.5 ksi) against 90 MPa (13.1 ksi) for 1050 — about 72% more. Tensile strength is 195 MPa (28.3 ksi) vs 110 MPa (16 ksi).
Which is cheaper, 1050 or 5025?
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, 1050 or 5025?
5025. Its machinability rates fair (38/100) against poor (30/100) for 1050.
