Aluminum 1100 vs ER5654

Aluminum · grade comparison

Aluminum 1100 and ER5654 are both aluminum grades. ER5654 is the stronger of the two: tensile strength 240 MPa (34.8 ksi) against 125 MPa (18.1 ksi) for 1100, about 92% more. ER5654 is the more ductile: elongation 20% versus 12% for 1100, and ER5654 is harder (58 HB vs 32 HB). 1100 runs hotter in service (120°C vs 65°C continuous) and 1100 conducts heat better (222 W/m·K vs 127 W/m·K). On the shop floor, 1100 sits in a lower cost tier (budget, $) than ER5654 (high, $$$$).

1100Choose it when the part sees heat, or when cost is the deciding factor.

ER5654Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
