Alloy Selection

Three types of metal alloys can be considered for this application -

Zinc ZA8

Aluminum

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 Ž130, Aluminum A380) for the fan housing, based on density, thermal conductivity, strength, ductility, and modulus as shown above.
