This
keychain magnet offers strong magnet power in a handy keychain. It is
perfect for jewelers, recyclers, coin dealers, or anyone that needs to
make fast assessments of jewelry, antiques, and industrial metals for iron, nickel, or cobalt content.
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.
Featuring a durable neodymium magnet housed in a metal shell, it holds over 2.5 pounds.
A powerful N40 grade (2.5 lbs
pull strength) neodymium rare earth magnet is encased in an aluminum
housing for durability and comes with a stainless steel split ring. 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 steel plated 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
