Envistia Mall Keychain Magnet for Testing Brass, Gold, Argent, Ferrous

These 12mm nickel-plated keychain magnets offer strong N42 neodymium magnet power in a convenient keychain design. They are suitable for jewelers, recyclers, coin dealers, or anyone in need of a portable magnet for testing iron, nickel, or cobalt content. With a durable neodymium magnet enclosed in a nickel-plated metal shell, each keychain magnet can hold over 2.5 pounds of weight. Use the magnet to determine if jewelry is silver or gold plated by checking for ferrous metals in the base material. If the magnet reacts to the jewelry, it is not pure gold or fine silver. The same applies to brass and bronze antiques, as many are simply plated over steel or iron. The magnet can also help differentiate polished aluminum from stainless steel and is useful for testing industrial metals for recycling purposes.
