These Metal Tester Magnets are powerful neodymium magnets that come in a convenient keychain form. They can be used to quickly assess the ferrous metal content in jewelry, antiques, and industrial metals. The magnets are particularly helpful in identifying whether jewelry is made of fine silver or pure gold, as a response to the magnet indicates the presence of other metals. Additionally, the magnets can help distinguish between polished aluminum and stainless steel. With a durable neodymium magnet housed in a metal shell, these keychain magnets are a reliable tool for anyone in the jewelry, recycling, or metal industries.
They are perfect for jewelers, recyclers, coin dealers, or anyone that needs a convenient, easy-to-carry magnet to test for iron, nickel, or cobalt content. Type: Neodymium Magnet Keychain. 2x (2 Pieces) Neodymium Magnet Keychain with Keyring.
