Zinc Alloys for High Damping Applications–A First Progress Report 880287

High damping capacity materials are useful in attenuating vibrations in mechanical structures such as functional automotive bracketry. The intrinsic damping properties of zinc alloys have only recently been systematically measured. Low and high frequency damping experiments have been conducted on die cast zinc alloys. and damping capacity has been measured as a function of temperature at high frequencies. The alloys show excellent damping properties over the range from 5 Hertz to a few hundred Hertz. for service applications from 40-80°C (104-176°F).
