Sources for magnets

edited March 11 in Magnets

Made a list of sources for N52 magnets, only some have coating options that are supposed to be biocompatible, I was wondering if anyone had any interaction with these sources before or if I am able to provide new options.

Based in the USA, lots of options here: discs, cylinders, rings and tons of sizes, the one depicted has a nickel - copper - nickel triple plated coating but, they have epoxy and gold options as well.

Based in Israel and can produce N55 magnets, this is a commercial source and requires contact directly with the company, they are made to order (size/shape and coating).

Based in China, this is a commercial source and requires contact directly with the company, they are made to order (size/shape and coating), they also can coat their magnets with Everlube, a biocompatible coating among others (Passivation, Parylene and PTFE).
This source only produces up to N51 at best.

I found over a dozen more sources if more are wanted.

    Yes, but you need to ask about the coating process. TiN can demagnetize the NdFeB if coated using most techniques because of the heat, and you have to make sure they don't have holes in the coating a micron across.
