Guitar Pickups: Alnico Magnets vs. Ceramic Magnets
Alnico Magnets vs. Ceramic Magnets
Does magnet type in a guitar pickup really matter?
----- It only doesn't matter if tone isn't an issue.
We say that in jest but as the saying goes there is much truth in jest! Each component serves a purpose and like anything in life, we use certain things to achieve certain results and at the end of the day, much comes down to personal preference and each one's unique ear for tone which is different in everyone.
So when it comes to magnets, each serves a purpose and, of course, each comes from a different source which impacts cost, availability, and characteristics. Because many of today's magnets are manufactured and not, necessarily, purely natural, the result comes at a cost.

Alnico Magnets vs. Ceramic Magnets Characteristics
Tonal Characteristics of Alnico Magnets
Alnico pickups have diminished power when compared to Ceramic magnets. This diminished power allows for more dynamic depth or tonal spectrum in a pickup.
- Dynamic Depth
Because of the compromised power of Alnico pickups, the reduced power seems to allow for increased dynamic depth allowing for a greater tonal spectrum. It "appears" that the lower initial impact of the wall of sound, allows for the capture of greater highs and a tighter response with the low end. This is merely based on experience and opinion.
The chemical composition of Alnico magnets is Aluminum, Nickel and Cobalt. The process required to cast these elements together yields a flavoring different than Ceramic or Iron pickups. Much like the ingredients of mom's perfect spaghetti sauce, unique elements yield specific results. There is a certain character of warmth to Alnico pickups that is lacking in Ceramic pickups which can only be described in terms of depth and warmth or sterility and as anemic. This is not good or bad just a matter of character and, perhaps, opinion and ear.
The chemical process required to cast three elements together is not only more expensive due to 3 elements, but the fact that three elements are needed, in itself, increases the cost. It is known that the "sinistering" process achieves greater mechanical functionality but increases the manufacturing cost. This results, on occasion, of Alnico pickups being priced higher than the average ceramic pickup.
Tonal Characteristics of Ceramic Magnets
By far, without question, Ceramic magnets are more powerful. For this reason they are often sought out for application where tonal power is required rather than tonal dynamics. If you need power, a Ceramic magnet is usually a good first response.
The general equation is that more power equals diminished sustain. This is true no matter the magnet. So if you want true natural sustain, you may want to compromise on overall magnet power. However, with today's amps, the lack of sustain can usually be remanufactured through electronics and power.
In most cases, if power is the primary characteristic in choosing a pickup, then often the other factors or characteristics of that magnet become secondary or a non issue. Likewise, in the case of Ceramic magnets, it "appears" that Ceramic magnets often lose warmth or overall tonal spectrum. They have often been called sterile or anemic in this area of description. However, that being said, most who choose ceramic magnets are not after tonal warmth but power.
The chemical process required to sinister ceramic or ferrite magnets is far more efficient in both process and cost than its counterpart, Alnico. For this reason, in reducing costs. You will find pickups being made of Ceramic magnets. It gives the player the "feel" and "appearance" of having a powerful guitar especially in practice settings.
Magnets in different form for different functions
Why Alnico over Ceramic
Bottom Line: You get what you pay for.
Ceramic magnets are cheaper to make and very generic in function. This yields a very powerful, stale magnet, which is very versatile in function, but not flavorful in application.
The higher cost of Alnico magnets has caused many pickup manufacturers to dup and deceive buyers into believing the tone is better. It may be more powerful, which is useful --- rarely, but never yields quality and tasteful tone.
If you listen to a guitar for warmth, tonal spectrum, dynamics, sustain and ability to recapture playing technique and nuances, most musicians who plays for this style choose Alnico magnets. In addition, there is a strong chance the musician who inspired you used Alnico magnets (in conjunction with tube amps). Mass production does not equal high fidelity. In final, if you want the warmest and purest, non-colorized tone, this requires purity. Purity is more expensive than the norm. Ceramic is ordinary and cheap, Alnico requires more effort to produce and is more expensive.
Remember, you get what you pay for. Manufacturers try to increase profits by using Ceramic magnets, don't give in to the bottom line. Choose Alnico, in fact, demand it.
