Could be like Gasoline the price fluctuates with speculation?
Although the Jump was last month and it has receeded
London Metal Exchange: Cobalt
Sad part is that Alnico performs far better than Neo in speaker motors. Neo is Very temp sensitive.. at 100C most all Neo variants demagnetises.. Not good. But then it's beyond normal for speaker motors to get to even that level of overheat.. or not?
Besides Neo self oxidizes into toxic powder as soon as the encasing plating fails.. typically far Sooner rather than later. Even I have few examples of that self destruction. Safely, in sealed containers.
Whereas the Cobalt alloy Alnico has a 2000 year Utterly stable Gauss with a 2000 year projected Half Life . Also has ~600+ Celcius Currie point and NEVER actually needs a remag.
(Unless owned by someone who has no clue and the 'servicing' is by some inept disreputable )
Interesting material indeed.. even beyond strategic (Nuclear warhead) uses.
Alniico is one of the time proven better motor components of any worth owning speaker.
Likely some makers are starting to charge even more than their costs

.
Profit is where they can squeeze / find it.. increasingly the way of the world.
Too much? don't Buy
