Keychain Magnet for Testing Brass, Gold, Silver, Jewelry. Coins and Ferrous Metals
0.47" (12mm) Diameter, Powerful N52 Grade Neodymium Magnet
This keychain magnet keychain magnet offers strong neodymium magnet power in a handy keychain. It is 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 N52 neodymium magnet housed in a nickel plated metal shell, each keychain magnet has a pull force of over 3 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. If the magnet sticks to it, it is likely just brass plating over steel or iron.
This strong magnet is very handy for testing industrial metals for recycling. The keychain magnet features a powerful 12mm N52 grade (3 lbs minimum pull strength) neodymium rare earth magnet encased in a nickel-plated steel housing for durability and comes with a stainless steel split ring.
This magnetic keychain is strong, small, light in weight, and easy to carry. You can put it in your pocket or purse when you go out. It provides you with a versatile multi-functional magnetic testing tool.
Use it for:
- Identifying most steel grades and metal alloys that contain iron, nickel, or cobalt.
- 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 bronze-plated steel items (handy in the antique market and hardware store).
- 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.
- Hanging keys, notes, pictures, blueprints, etc.
- Also handy for science experiments and demonstrations involving ferromagnetism
NOTE: This keychain magnet is designed to identify magnetic and non-magnetic materials, and other experiments using magnetism. It is NOT powerful enough to release security and inventory control tags.
