Non-ferrous inclusion detection??
Non-ferrous inclusion detection??
(OP)
Does anyone know if there is a non-ferrous inclusion detection system out there for aluminum rod? It would need to be an in-line system. I have heard mention of infrared cameras that may work for this.

The eddy current method can be used for defect detection in non-ferrous metals. Contact Magnetic Analysis or Foerster for more information on their products:

You need to investigate or know what your threshold limit is for inclusion size and geometry. In other words, what is the maximum size you can tolerate in terms of width/length or in some cases maximum inclusion diameter. You need to go into this project knowing that you will not be able to detect all inclusions in an on-line process. So, be prepared to discuss with vendors what your limits need to be for detection of inclusions.

Yes straight ET will work. It is what we use on SS and Ni alloys. Just because material isn't ferromagnetic does not mean that it does not have magnetic properties.
Surface ET is easy because you can use higher freq and get great sensitivity.
