The magnetic fly patch is made from an aircraft grade aluminum alloy that will stand up to years of use. The aluminum housing holds extremely strong, rare-earth neodymium magnets which were specially chosen to be delicate enough so flies can be easily removed, yet strong enough to hold onto the backing plate with an iron grip. On top of that the stainless steel plate is a high grade stainless steel alloy that holds firmly onto the magnet, but will still resist corrosion, and last for many years to come.
