Neodymium Ring Magnets 

Powerful Neodymium ring-shaped magnets are manufactured using an alloy of rare earth minerals. This raw material has enabled Neodymium magnetic products to become the most powerful magnets on the market. This Neodymium ring magnet example has N35H Grade magnetic strength which gives this ring the ability to withstand higher operating temperatures than the 80℃ limit of the majority of Neodymium magnets. Circular ring magnets of this type contain heat resistant additives in the alloy that allow it to remain functional at temperatures up to 120℃. This capability can be an important requirement in various manufacturing processes and scientific applications where high temperature environments are necessary to maintain hygienic or sterile conditions. High speed electric motors which produce heat, like those found in cordless power tools, use strong Neodymium magnets to generate power and can also derive significant benefit from this type of heat resistant Neodymium magnet.
