I would too like to know, as I believe you are talking about Spotcheck which is a product of Magnaflux. As an aluminum part can not be checked with traditional magnafluxing using ferrous metals and an magnetic field.
I am a Welding Engineer by trade, so I think that the Spot check method was used, it uses dyes to show cracks in aluminum.
Hope this helps clarifies some.
