Description of π Ferrous Keychain Magnet Test for Improved Hanging
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). Generally, the magnet test is only the first test performed, before density and acid testing. Identify/sort chrome plated items from polished aluminum, silver, and non-magnetic grades of stainless steel (chrome plating requires a nickel layer, which is magnetic). Identify and sort solid brass and bronze from steel-plated items (handy in the antique market and hardware store). Features a durable neodymium magnet housed in a metal shell, it holds over 2.5 pounds. Dimensions: 0.47 inches wide at its widest point x 1.57 inches long (12 x 40 mm).
Pros
- Identifies/sorts chrome plated items in polished aluminium, silver and non-magnetic stainless steel (chrome plating requires a layer of nickel which is magnetic).
Cons
- Doubtful
Pros
- Identify counterfeit/plated jewelry, often made from steel or nickel alloys as the base material (some alloys such as nickel silver and cupro-nickel are non-magnetic despite the presence of ferrous metals). Typically, the magnet test is only the first test performed before the density and acid tests.
Cons
- Not sure
