Re: CuNiFe Exists! ( a little )
Thanks for the kind words guys. We have worked really hard on this and when I discovered a stash of CuNiFe, decided to go ahead and make something with it!
The tough thing about making CuNiFe is that it needs to be manufactured as close to it's finished form as possible. In other words, if you're making .210 diameter threaded rod magnets, the CuNiFe needs to be manufactured in rod form close to the final, finished diameter.
Bear with me, I have learned more about this stuff than I ever wanted to know because I had to know the material I bought would actually work in this project. Not all CuNiFe will!
During the final heating/annealing process, a very strong magnetic influence is applied to the CuNiFe to orient the magnetic properties of the material. If you were to take a 12" x 12" x 12" block of CuNiFe and try to machine these parts from it, they probably wouldn't work because of the material's magnetic orientation.
In short, someone having this material made, would also need to have it "oriented" and that means "custom run" to the tune of $60K for starters.
I have enough for about 30 pickups that will all be spoken for before we can even finish making them, the reason I'm not pushing to sell anything here, just share the info.
In our research, we have also turned up a few interesting facts concerning WRHB's.
1) CuNiFe really needs to be re-charged every 20 years or so. ALL of the pickups we have tested, dismantled, re-wound, or passed through our hands have had weak magnets. They measured about 30% of their potential gauss rating. We have taken several dismal sounding WRHBs and simply charged the magnets restoring them to their former glory! But you need to do it with an industrial strength electronic magnet charger. Passive magnets do not sufficiently charge this material. ( I told you I know more about this stuff than I ever wanted to know! LOL! )
2) Fender used at least 3 different spec bobbins and two different wire types, (enamel & poly) in winding their WRHBs. The spec is supposed to be 6800 winds but the few dead coils we've unwound had a count closer to 6600 winds. All of these variations on specs make a noteable difference in sound. The reason you may like or dis-like these pickups may very well have to do with the particular spec and magnet gauss you tried.
All WRHB's are NOT created equally!
