How are Alnico magnets important to electric guitars?

Our magnets are used in an array of applications including filtration and separation to everyday objects like smartphones, one use of alnico magnets which may not commonly be known is in electric guitars. So, if you’ve ever been guitar shopping or though about learning to play, you’ll have stumbled across the term alnico pickups. But what exactly are alnico pickups and why are alnico magnets used? What are Alnico magnets? Alnico is an acronym comprising of the first letter of the three metallic elements used to produce the magnets Aluminium,... Read More

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 Ferrite Magnets made?

The process for manufacturing ferrite magnets, also known as ceramic magnets, is not as costly or sophisticated as producing rare-earth neodymium magnets. The chemical compound of ferrite 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 ferrite magnets begins with calcining a finely powdered mixture of iron oxide and strontium carbonate to produce... Read More

How are Neodymium magnets made?

Neodymium magnets are technological marvels and the process for creating them is sophisticated and delicate. The main ingredients of a neodymium magnet are neodymium itself, iron, and boron; the chemical compound known as NdFeb. The exact ingredients depend on the grade or strength of magnet being produced. However, the production process for different strength magnets sees the same size different stages required to produce a neodymium magnet. . Step 1 – The Mix Firstly, all the elements to make the chosen grade of magnet are placed into a vacuum induction... Read More
