Compared with other permanent magnets, Wired Telephone Disc Ferrite Magnet is cheap. It is most suitable for most sensitive, but need not very high performance applicaitons. As this is a non-metal magnets, it is the ideal magnets for applications that require non-rusty magnets in humit envirument.

Ferrite magnets are easy to recognise due to their dark-grey colour. Unlike neodymium magnets, they don't need any coating thanks to their non-corrosive material. We carry ferrite magnets made of strontium ferrite (SrFe) in our assortment which are all axially magnetised. Ferrite magnets are also known as hard ferrite magnets, ceramic magnets or ceramic permanent magnets. The advantages of ferrite magnets at a glance:

Temperature-resistant from -40 °C to 250 °C

Rust-proof and therefore ideal for outdoor use


Shenzhen TOPMAG sales office was established in 2012. HT Factory was founded in 2004. It is a company specialized in R&D, production and permanent magnet. The company is committed to providing solutions for customers and providing products with stable quality and excellent performance.

Production Process

Workshop Viewing

The process is to mix all raw materials ( Rare earth, Iron...), and melt to pieces

The magnetic powder is shaped and oriented at this process. The magntic direction is defined now. but now the magnet is without any magnetism.

After pressing, the density of the magnets are still very low. Thus sintering is essential to enhance the magnet density to the standards.

When the magnet is sintered, the magnetic properties are fixed that we will inspect the properties. Then the magnets will sent to be machined into customized shapes. Finally all the magnets will be coated to avoid rusted. The poplular coatings are NiCuNi, Epoxy, Zinc...

Products Magnetization

We can do all the magnetization for neodymium magnet including: Axial magnetization/Diametrical magnetization/Radial magnetization/Inner-diameter

multi-polar magnetization/Outer diameter multi-polar magnetization/Surface magnetization/Complex magnetization/Encoder magnetization/Skewed magnetization.

Packaging and Delivery:

Standard packaging for air,boat and delivery. Box sizes will be adjusted base on the quantiy

Standard Packing and Shipment of Ferrite Magnet

1. Package: Vaccum Bag, White box, Carton, Wooden case; Special Package: Plastic tube, Paper

2. Contract price with FedEx, DHL, UPS and TNT to minimum your shipping cost.

3. Experienced shipping forwarder for Ocean and Air shipments. When the Net weight of the magnet is over 200Kg, by sea is the best way.
