Aluminum A380

  Target Zinc ZA8 Aluminum
Thermalcast 130
Aluminum A380
Density (#/in^3) <0.10 0.24 0.095 0.096
Thermal Conductivity (W/mK) >120 115 130 96
Ultimate Tensile Strength (ksi) >40 54 46 47
Tensile Yield Strength (ksi) >20 42 24 23
Ductility (% Elongation) >3% 6-10% 4% 4%
Elastic Modulus (MSI) >10 10.2 10.3 10.3

Choose an alloy (Zinc ZA8, Aluminum-Thermalcast ®130, Aluminum A380) for the fan housing, based on density, thermal conductivity, strength, ductility, and modulus as shown above.
