Product Description

Product Description:
Ferrite rectangular magnet Ceramic magnet iron ferrite magnet
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

Application of Ceramic Ferrite magnet: Ferrite ring magnets, also known as ceramic ring magnets, are a type of permanent magnet made from iron oxide and is one of the most cost-effective magnetic materials. 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.
How to separate strong magnet: 1. Slide one magnet off the top of the stack
                                                            2. Lift and tilt the top magnet away
                                                            3. Lift the magnet to free it from the stack
How to restore to their original: If you need to put the magnet back into the whole magnet, please put it back slowly, starting from the edge at a close distance. Be sure to hold the magnet with your hand until the magnet has moved in. Do not attract the magnet directly from a distance, otherwise the product will break, or the fragments will hurt people.
Standard package of magnet by air: If magnet shipped by air, there is a kit of iron sheet inside of carton to shield the magnetism. 
Standard package of magnet by sea or by train: If magnet shipped by sea or by train, there is no iron sheet inside of carton. It could be exported as general cargo.
Warning: The magnet has strong magnetism. Keep out of reach of children under 16. SWALLOWING IS STRICTLY PROHIBITED!
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 99.5%.
