Keyring magnet assembly, helps you make fast assessments jewelry, antiques, and industrial metals. Carry it everywhere! Now with a 60% stronger magnet than our previous version. Find jewelry that is silver or gold plated 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. Same goes for brass and bronze antiques, many are just brass plating over a steel or iron core. 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. Metal recyclers, pawn shop owners, jewelers and treasure hunters should keep this on their keyring at all times. A powerful 5/16″ N52 grade (6.5 lbs pull strength) neodymium rare earth magnet is encased in 6061 aluminum for durability and comes with a stainless steel split ring and a vinyl cap. Use it for: Identify most steel grades and metal alloys that contain iron, nickel, or cobaltIdentify/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/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 notes, pictures, blueprints, etc.Also handy for science experiments and demonstrations involving ferromagnetism Dimensions are: 3/8″ (10mm) diameter 1 1/2″ (38mm) body length 1/2″ (13mm) diameter stainless steel split ring 1 3/4″ (45) overall length with ring extended 0.3 oz (10g) weight 6.5 lbs (3kg) pull strength (this IS NOT the lift rating, which would be reduced by a number of factors, including material composition, mass, shape, presence of coatings, etc.) The aluminum casing protects the magnet from chipping and breaking, common with unmounted rare earth magnets, and a vinyl cap is provided for when the magnet is not in use. These are hand made in the USA. See my other listings for different versions of this item; we sell larger versions as well as magnets mounted in brass and copper.

Strongest Test Magnet 54lbs/24kg N52 Rare Earth Neo Metal Silver Gold Check KM06
Retrieval and Metal Testing Magnet. Made in the USA Very, very powerful. Most rare earth magnets are difficult to handle and fragile, not so good for industrial use. Not to mention, they are they are easily misplaced or lost. We have mounted an extremely strong 1″ diameter x 1/2″ cylinder N52 grade neodymium-iron-boron magnet in 6061 aluminum for industrial and hobby use. It comes with an extra heavy duty split ring for attaching a hook, rope, wire, or fishing line. Here are some possible uses: Hang stacks of paper or thick documents. Identify and sort steel grades and ferrous metal alloys.Identify/sort chrome plated steel items from polished aluminum, silver, and non-magnetic grades of stainless steel Identify/sort solid brass and bronze from plated steel items (handy in the antique market and hardware store) Identify/sort some types of costume (fake) jewelry, which often use steel alloys as the base material under the plating.Use as a very powerful magnetic pickup, not like those 1/2 pound jokes at the hardware store.Attach to your fishing line and cast away. You will find all sorts of sunken goodies. I am told that if you live in a big city, bridges are an excellent place to go «magnet fishing.» If you want to retrieve really big items (like engine blocks), use this magnet as an underwater finder, when it latches on to something, you can drop a very large normal magnet and pull up as much as you or your boat winch will lift.Also handy for science experiments involving ferromagnetismThe magnet insert is rated at 54 lbs pull strength (as with all magnets, this rating depends on the magnet mating to a smooth, flat, unpainted steel surface, and this is NOT the same as the lifting power, which depends on a number of factors). Dimensions are: 1-1/8″ (30mm) diameter x 7/8″ (22mm)tall head 2″ (50mm) overall length 3/8″ (10mm) diameter handle 1/2″ (12.5mm) diameter heavy-duty stainless steel split ring. The aluminum casing protects the magnet from chipping and breaking, and makes removing iron and steel shavings much easier. A removable vinyl cover is also included. We strongly recommend that you keep the vinyl cover on when not in use, and even in most cases that you are using it. These are made in the USA.
