internal DAMPING in aluminum alloy
internal DAMPING in aluminum alloy
(OP)
I'm looking for some detailed datas about the internal damping factor of cast aluminum alloy and wrought aluminum alloy. This factor is nearly unfindable (matweb included).
Thanks
Thanks





RE: internal DAMPING in aluminum alloy
If "damping" of noise or vibration is your main issue, why not try looking into cast Magnesium ? Much better damping properties.
Good hunting !
RE: internal DAMPING in aluminum alloy
Cast magnesium is an expensive choice and before changing material we must evaluate the real benefit, however I will keep it in mind.
RE: internal DAMPING in aluminum alloy
This all depends on the volume required of the part of course !
Sorry for the lengthy response, Al & Mg casting is what I do in the UK and is very close to my heart !
I've been thinking a bit more about the DAMPING DATA, fixed data will be impossible to find as it is so dependant on shape, cast process used, alloy etc., etc..
I have just spoken to a colleague at a company called Calcom/ESI. If you direct your question to mail@calcom.ch for the att'n of Adrian, he will find out what data they have. They are leaders in Casting software for F.S.A. and one specific area they excel in is vibration damping.
Good luck !
