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.Featuring a durable neodymium magnet housed in a metal shell, it holds over 2.5 pounds.Determine if jewelry is silver or gold plated by testing if ferrous metals are used as the base metal (excluding some nickel alloys). If a magnet responds to jewelry, it is not fine silver or anything near pure gold. The same is also true of brass and bronze antiques, many are just brass plating over steel or iron. The magnet can also be used to determine polished aluminum from stainless steel in most cases, and is very handy for testing industrial metals for recycling.Features a powerful N40 grade (2.5 lbs pull strength) neodymium rare earth magnet encased in a plated brass housing for durability and comes with a stainless steel split ring.Product SpecificationsType: Neodymium Magnet KeychainMaterial: N40 NeodymiumDimensions: 0.47 inches wide at its widest point x 1.57 inches long (12 x 40 mm) Net weight 0.6 oz (18 g) Review: Good - Good Review: Original and good quality - all good ## Features - Ideal for metal recyclers, brokers, antique buyers, collectors, or anyone that needs a convenient, easy-to-carry magnet to test for iron, nickel, or cobalt content. - Identify fake/plated jewelry, which often has steel or nickel alloys as the base material (some alloys, like nickel-silver and German silver are non-magnetic, despite having ferrous metals present).
