How are Ceramic Magnets made?

The process for manufacturing ceramic magnets, is not as costly or sophisticated as producing rare-earth neodymium magnets. The chemical compound of ceramic magnets is SrO-6 (Fe2O3), a combination of strontium carbonate and iron oxide. Due to their chemical make-up it means they are extremely resistant to demagnetisation through heat and corrosion, although, like neodymium magnets they are very hard and brittle. Step 1 – Calcination The production of ceramic magnets begins with calcining a finely powdered mixture of iron oxide and strontium carbonate to produce a metallic-oxide material. In some...

How Are Samarium Cobalt Magnets Made?

Samarium cobalt magnets are widely produced and the permanent magnets are primarily made up of samarium and cobalt but some grades will also contain varying small amounts of iron (Fe), copper (Cu), hafnium (Hf), zirconium (Zr) and praseodymium (Pr). A number of common manufacturing processes can be used to produce samarium cobalt magnets but typically, a method of reduction and melting is used followed by a process of bonding or sintering the raw material to form the magnet. Bonded Samarium Cobalt Magnets . . Step 1 – Heated Firstly, the... Read More

How are Cast Alnico magnets made?

Alnico magnets have now been manufactured for over 100 years, in which time the process has not drastically changed. Alnico magnets are permanent magnets that are primarily made up of a combination of aluminium, nickel and cobalt but can also include copper, iron and titanium. In this blog we will be explaining the manufacturing process of Cast Alnico, a larger Alnico magnet weighing tens of kilograms which will nearly always be produced by casting. Step 1 – Foundry Furnace Each grade of Alnico has a special recipe in terms of... Read More
