We are looking for an alternative to standard DOM tubing for a 4 link. And I was curious if anyone had any success with ADI for suspension systems? I've done a lot of research and I can only find an article on when Ford used for the 99 Mustang as well as some older info on rear ends. But nothing new.
If you have perhaps you can answer some items I am unsure about. Mainly I am concerned with the ductility of the material. Normally we would use a DOM tubing, which in itself is light weight, strong, tuff and ductile (elongation before break (15-20%). As well there is a substantial difference between the yield and tensile, which is sort of a rough indicator of the toughness.
While adi has 110 tensile, 75 yield and an elongation of 11%. As well the reduction of error is low around 10%. Based on these numbers it would not be as tough or ductile. But further research has shown this not to be the case. As impact and fracture strength are quite high. 字串3
The reason for the change is purely cosmetic, we need something nicer than a simple tube.

ADI is used in a number of other suspension applications, including control arms for several Ford vehicles. It is not as tough or ductile as a DOM steel tube, but when properly designed, can provide acceptable properties. Casting quality is certainly of primary importance, which means that defects like porosity, cold shuts, etc. must be eliminated, or at least minimized to low stress areas. Have you talked to a casting supplier that works with ADI? Intermet or Hitachi are the two suppliers you should contact for automotive suspension components.

If you are a low volume manufacturer consider proof testing every part. 字串4
I was involved in the design and development of a complete front end suspension made from aluminium, it is certainly possible, and in fact has given us no problems so far. It's been in the market for 4 years now. I think BMW uses a lot of aluminium in their suspensions as well.

Thanks TVP I will contact a those people.
Greg, I would definitely like to do something in aluminum but I don't have the resources or experience with the material.

"the reduction of error is low around 10%"
Guessing that is your spellchecker gone mad, what did you mean to type? 字串6

seems to have a lot of useful data.
