I was looking at transformer cores for the past few months as I am looking to start winding my own trafos. The M6 silicon steel has been a favorite to many people - it is cheap, not that hard to find and has good parameters. However, I was looking into something more exotic, no matter what the price would be.
What I found so far is a material called Metglas Magnetic Alloy 2714 which shows superb qualitues - it has the lowest core loss, permeability is really high and will allow a much smaller core size, which means a reduction in the turns radius and thus less losses in the copper. There are a few companies that offer C-core laminations of this material. To me it looks like the ideal core material, any thoughts?
