Brass Washers vs. Rare Earth Magnets

[adamlau]

Was considering brass washers and MAGCRAFT 0.625 x 0.125 rare earth disc magnets to make up space at the end of battery tubes for appropriate tailcap contact. Assuming equal diameter and thickness, which of the two is preferred over the other in terms of lower resistance and higher conductivity?

Hello Adamlau,

I would lean toward the brass washers. They don't crumble when dropped and won't loose their magnetism over time.

Copper would be better yet.
