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

Smartphones & Magnets: All you need to know

Anyone working with or near magnets will have been made aware of the many health and safety warnings regarding magnets. One warning has always been that you must keep magnets away from computers, credit cards, and even your phone. So, do magnets pose a threat to phones and other modern technology? If so, what threats do they pose and how strong must a magnet be to damage a phone, and what parts of the device would be susceptible to damage? The whole idea can be traced back to older pieces...

How is the strength of a magnet measured?

When considering the ‘strength’ of a magnet there are several key measurements that all contribute to a magnet’s strength in different ways, which can be a little confusing. Also, when trying to determine or measure a magnets strength the answer will be dependent on what is meant by strength be it either the pulling force or magnetic field strength, which are both often referred to as strength. So below we will describe each attribute that contributes to a magnets performance and in turn answer the question how is the strength... Read More

What material is best for shielding a magnet?

Shielding a magnet or attempting to block a magnetic field is a subject that several of our customers approach our experts with on a regular basis, so we decided to examine what materials can be used to shield a magnet. Before learning how to shield a magnet it’s important to know that magnetic shielding does not block a magnetic field. No material can stop the lines of flux from travelling from a magnet’s north to its south pole. However, it can be redirected. The simplest example of this would be... Read More

What reduces a magnets performance?

All magnets have a ‘pull’ rating measured in kilograms which relates to how much force acting perpendicular to the magnet to pull the magnet from a steel plate, when in direct contact. The ‘pull’ rating is obtained and calculated under ideal conditions such as a thick enough steel plate which is perfectly flat and clean. As the pull force is slowly steadily increased and is absolutely perpendicular to the magnet face. However, in real world applications, perfect conditions are unlikely and there are six main factors which could affect and... Read More
