I was looking at a large transformer i was scrapping out the other day and I got curious as to what would be the best material for electromagnetic cores and am not finding much on the net. This transformer for instance has the typical stacked laminations that appear to be thin sheet steel (don't really know the actual alloy or material). Now I always thought that soft iron would be the best for a core. And then I was wondering if sintered iron in thin sheet form would be a better choice. I got to looking for sintered iron sheet stock (say .030") on the net and soft magnetic iron sheet stock of the same thickness (thought it would be interesting to experiment with both) and am just not finding a source. Have to believe this is something that is already made as a stock standard material for some industry, just not finding it. I have looked at Pacific Sintered Metals and at GNK and see that they both offer "soft magnetic" sintered metal products but I have yet to hear from them if they manufacture stock sheet material or were to get a small quantity for testing.
So the question to my learned friends here are : 1. Would sintered iron be better than sheet iron for an electromagnetic core and 2. Anyone have a source recommendation for sample quantities of thin sheets of either or both? Thanks Dach. -------------- next part -------------- An HTML attachment was scrubbed...
