Aluminum 5183 vs ER5654
Aluminum · grade comparison
Aluminum 5183 and ER5654 are both aluminum grades. 5183 is the stronger of the two: yield strength 145 MPa (21 ksi) against 115 MPa (16.7 ksi) for ER5654, about 26% more; tensile strength follows at 300 MPa (43.5 ksi) vs 240 MPa (34.8 ksi). 5183 is harder — 80 HB against 58 HB for ER5654 — which matters for wear surfaces and threads. ER5654 conducts electricity better (33 % IACS vs 29 % IACS). On the shop floor, ER5654 forms better (80 vs 70 out of 100) and 5183 sits in a lower cost tier (standard, $$) than ER5654 (high, $$$$).
5183Choose it when strength drives the design, or when surface hardness matters.
5183 vs ER5654: 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.
