FAQ
How long does it take for the magnetism to lose its strength?
If magnets are heated above 80-100 degrees C they will start to lose their magnetism. Theory suggest these permanent magnets would lose around 1-5% over 10 years however this depends on many variables. Once lost, the magnetism does not return and cannot be remagnetised.
What are neodymium magnets coated with?
The typical coating for a neodymium magnet is a layer of nickel followed by a layer of copper and then nickel again. However there are many different coatings used with neodymium magnets including gold, rubber and Polytetrafluoroethylene (PTFE).
Where is Neodymium magnets used?
Neodymium magnets are used in numerous applications requiring strong, compact permanent magnets, such as electric motors for cordless tools, hard disk drives, magnetic holddowns, and jewelry clasps.
How are neodymium magnets made?
Sintered Nd-magnets are prepared by the raw materials being melted in a furnace, cast into a mold and cooled to form ingots. The ingots are pulverized and milled; the powder is then sintered into dense blocks. The blocks are then heat-treated, cut to shape, surface treated and magnetized.
Can you weld Neodymium magnets?
You definitely cannot solder or weld to neodymium magnets.
