Ceramic magnets are manufactured using powder technology techniques. The primary raw material - ferrite - is made by using iron oxide and strontium carbonate.
Ferrite block magnets, also known as ceramic block magnets, are a type of permanent magnet made from iron oxide and is one of the most cost-effective magnetic materials. Their low cost, resistance to corrosion and high operating temperatures make ferrite magnets great value for money. Ceramic Ferrite magnets are low energy products, and they are usually used in assemblies containing mild steel or often chosen for applications where stronger permanent magnets, such as neodymium aren't required. Ferrite block magnets are incredibly difficult to demagnetize and are electrically non-conductive, so are ideal for applications that require a permanent magnet, such as loudspeakers and fridge magnets. Ferrite Magnet is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.
Besides they are very hard and brittle that makes them difficult to machine or drill. They also have a very good temperature tolerance with relative magnetic stability at temperatures of up to 250 Degrees Celsius.
• 250° maximum operating temperature
• Excellent resistance to corrosion
• High resistance to demagnetization

How to separate magnet from stack magnets
Usually, the neodymium magnt is packed as following picture show, but it also can be customized if you're selling it on Amazon, ebay or other sales platform, we are glade to design an attractive packaging for you!
Shipment of magnet: Magnet can be shipped by Air, Express, Truck and by sea. But it has to be shielded if by air or Express.
How to promise the quality: Quality is our culture! To ensure our quality, all magnets are produced with 100% new standard material rather than recycle or bad material. Besides our professional QC department will inspect the magnet for each stage, including magnet grade, coating, dimension, tolerance and pulling force for pot magnet, magnetic hook, fishing magnet or other magnetic assemblies. So that our magnet pass rate is as high as 99.9%.
Sample of ferrite magnet:Sample of ferrite magnet is available to provide within 1-2 days if we have it in stock. Otherwise, it takes 5-7days to custom.
MOQ of ferrite magnet: Usually we don't require special MOQ of ferrite magnet for you, small order is available to accept. If you ask for special custom magnet or pot magnet and it needs mold to produce, MOQ is decided as product details.
Custom service: Custom service is our advantage. Multimagnets has a professional technical team to support our customers. We can provide professional CAD drawing, strength simulation of magnet / pot magnet, even that Multimagnets can assist you to design a new magnet. For some Amazon customer, Multimagnets always provide free labeling and professional photos taking
