Review on Dowling Magnets Alnico Magnet Inches by Darion Wooten

I searched for these magnets for their high heat resistance after being disappointed with the loss of magnetism of samarium cobalt and ceramic magnets under the flames of Bunsen burners and propane burners. . Unlike those very strong rare earth magnets, these alnico magnets are extremely resistant to high temperatures (they remained functional after being heated to over 500 degrees Celsius). However, their strength is very low, so I recommend buying a neodymium or samarium cobalt magnet if magnet strength is required, while this product is optimal for high temperature environments.
