Re: pickup magnet materials/types
Magnet wise, ceramic and alnico are the two most common. Ceramic yields a flat eq response, while alnico brings a little something to the table, with each of it's variants being slightly different.

Re: pickup magnet materials/types
First you need a different coils and/or blades to match others than alnico and ceramic. Check out Bill Lawrence he is the guy who uses things like samarium or neodyminum.
The difference in alnico make the composition of the metals, they give a limit to charge the magnets and obviously a different kind of enhencing different frequencies of the guitar. The last thing is not totally clear, since guys like BL say it only a function of strength and a side effect called eddy current.
As a thump of rule: The higher the Alnico number, the more bass and more highs you have on a given coil. The mids are drawn back in this order, because the highs and lows get more dominant.
Newer Alnico get aged in hundreds of years, older magnet seem to contain a filler material which are reported cause an effect.
If you want to get deeper, make a search in these threads.
Hope that helps

Re: pickup magnet materials/types
Thanks for the information
Whats the difference between these materials or magnets?
1.) alnico
2.) ceramic
3.) samarium
4.) neodyminum
They have different frequency Frequency Response ?
Whats the curves like?
They all have different notches/peaks?
They all have different "Q" points? but why?

Re: pickup magnet materials/types
On a small technical note, this is a common misconception. Alnico numbers are assigned based on the date they were discovered/developed. Not on magnet strength. For example, for the common Alnico numbers:
A1: 7200 guass (isotropic cast)
A2: 7500 guass (isotropic cast)
A3: 7000 guass (isotropic cast)
A5: 12800 guass (anisotropic cast)
A5: 10900 guass (anisotropic sintered)
A6: 10500 guass (anisotropic cast)
A6: 9400 guass (anisotropic sintered)
A4 is a newer compound thats not on my list. Can't remember its guass.

I Love the A4 and it figures I'd pick the odd ball magnet....That makes me odd also....:smack: :laugh2:

Re: pickup magnet materials/types
My guess would be they're made of something like cobalt nickel and aluminium... I don't know why... just a feeling

Re: pickup magnet materials/types
Is it just different Mixtures of cobalt, nickel and aluminium?
What kind of magnets were in the fender's 50's guitars?
what kind of magnets were in the fnders's 60's guitars?
Does the magnet have alot to do with the twang or frequency response?
Or is it the number of wire turns thats makes the big difference?

Re: pickup magnet materials/types
I'm pretty sure they used A3 on the original pickups in 54, at least Lindy Fralin says so. I'm pretty sure they used A5 and A2 mostly, with more A5s. By the 60s they were using all A5 magnets I believe, but I could be wrong, more then likely I am.
Both magnet and number of turns of wire, along with wire gauge, matter a lot in the voicing of the pickup. Starting with the EQ of the magnet, the gauge and number of turns can drastically change the EQ of the pickup, though it will still retain the magnet's qualities somehow. Take a Custom 5 pickup for example, which has an A5 magnet and a lot of wire turns. The A5 gives the magnet good high-end and low-end, but lacking in the mids. The many coils of wire should dampen the high-end and increase the mids and low-end, but still the Custom 5 has a good bit of treble and a lot of bass, the qualities of an A5 magnet.
I'm not sure if I'm right about all this, so don't completely take my word for it, someone who's been around here longer would know this stuff better then I.
