Product Description

These high-performance N55 neodymium disc magnets deliver exceptional magnetic strength in a versatile small format. Made from premium rare earth alloy of neodymium, iron, and boron, each magnet generates impressive 0.99 lb pull force with superior magnetic properties compared to standard grades.

The magnets feature durable nickel-copper-nickel coating to prevent corrosion and ensure extended service life. Despite their powerful magnetic capabilities, the brittle ceramic-like construction requires careful handling to prevent damage from impact or sudden attraction.
