Some magnets are in a plastic base other s feel a bit more stone like because they ve been moulded in a ceramic.
Do ceramic magnets rust.
Some grades of alnico magnets do contain traces of iron and therefore will display some light surface corrosion over time if exposed to water.
Alnico and ceramic magnets both resist corrosion naturally although they don t provide the same level of magnetic performance of rare earth samarium cobalt and neodymium magnets.
Do not use for lifting over people.
With a few restrictions magnetic tapes and sheets can also be used outside.
Unless there are some sort of iron filings on the surface that could rust i think you d be ok.
Do ceramic magnets rust manufacturers factory suppliers from china we are keeping chasing win win situation with our clients.
On the other hand water proof neodymium and ferrite magnets are ideally suited for that purpose.
Please always ensure that bonding surfaces are clean and dry prior to bonding.
Neodymium magnets are also very brittle and will crack under stress.
You can find detailed information below.

Neodymium magnets are relatively more expensive than ceramic magnets.
We warmly welcome clients from all over the world coming over for a visit and establishing long term relationship.
Variations in material condition will significantly reduce these ratings.
Ceramic magnets are often assembled into products using superglues such as loctite 325 or other epoxies.
Ferrite magnets also known as ceramic magnets are made from iron oxide and as a result they simply do not corrode even when submerged in water.
A case protects the magnetic material.
Regular neodymium magnets are very susceptible to rust which is why we do not recommend them for exterior applications.
They rust very easily and extra steps must be taken to protect them from corrosion.
I would paint the magnets with something like a clear lacquer to minimise the risk.
The only sure conclusion is that corrosion is coming though it is hard to predict when.
The first magnet to fail showed a rust bubble after about 1 week.
Maximum pull ratings are based on direct contact with rust free and unpainted iron plate.
The last magnet to rust didn t start showing problems until after a month.

Ceramic magnets do not need to be protected for surface rust.
Ceramic magnets bonding methods.
They lose their magnetism if exposed to temperatures above 175 to 480 degrees fahrenheit depending on the exact alloy used.
Hobbies crafts and science round ceramic industrial ferrite magnets push pin magnets fridge magnets whiteboard magnets.
A thin film of magnet powder on the surface is common.
You could make them quite pretty.
