Stronger magnets don’t always mean better performance
When selecting a magnet, it’s easy to assume that the strongest option will deliver the best result. In practice, over-specifying magnetic strength often introduces avoidable issues. Excessive pull force can make products difficult to handle, increase costs unnecessarily, and create challenges during installation, adjustment or removal.
The most effective approach is not maximum strength, but selecting a magnet that provides the appropriate magnetic performance for the application. This is where our 40 years of experience can help make the difference.
Not all magnets perform the same
Magnets vary widely in material composition, behaviour and suitability for different environments. Factors such as temperature resistance, flexibility, corrosion tolerance and operational lifespan are all determined by the magnet type and construction.
Two magnets of a similar size - or those that appear visually identical - can perform very differently once in use. Selecting magnets based solely on appearance - because one that looks similar worked before - or headline pull-force figures can lead to reduced performance, inefficiency or premature failure. Just because a replacement magnet looks similar doesn’t mean it will perform the same - extruded products, neodymium magnets and magnetic sheets can appear alike, but their actual behaviour and suitability can differ significantly.
Magnetic pull force isn’t the full picture
Initial magnetic grip is only one element of overall performance. In real-world applications, factors such as air gaps, surface finishes, coatings, load direction and long-term use all play a significant role.
Laboratory-style performance doesn't always translate directly once a magnet is installed and exposed to everyday conditions. Understanding how magnets behave in practical environments is essential when specifying for reliability and longevity.
Magnets are increasingly sustainable
Magnets are often seen as an unsustainable product. However, this perception no longer reflects the full picture. A growing number of magnetic products entering the market now offer sustainable alternatives. With sustainability becoming an increasingly important consideration for businesses in the UK and around the world, planning ahead is essential. This is why we have worked over the years to include more sustainable options in our range.
For example:
-
supamag Ultra is a sustainable alternative to conventional magnetic sheet. At just 0.45 mm thickness, compared to the industry standard of 0.75 mm, ULTRA is up to 50% stronger, 40% lighter and 40% thinner - allowing you to do more with less. Speak to a technical advisor today.
-
RE:Move is a magnetic tape with removable adhesive. Unlike traditional magnetic tapes, which are discarded after use on point-of-sale displays, RE:Move allows the magnet to be separated from the base material, giving the option to reuse or recycle both components. Reach out to our product experts.
-
warmroom Magnetic Radiator Foil and secondary double-glazing kits support energy efficiency. warmroom has been independently tested at the Salford Energy House, showing up to 66% reduction in heat loss through walls during peak periods, and an average 2.9% reduction in gas consumption for space heating. Secondary double-glazing kits add an extra insulating layer to existing windows, helping to retain heat more effectively. Contact us to find out more.
These examples illustrate that, when specified thoughtfully, magnetic products can now deliver both performance and sustainability benefits.
Why early magnet specification matters
Leaving magnet selection until the final stages of a project often limits options and forces compromise. Early consideration of magnet type, strength and behaviour allows designers and engineers to optimise performance, control costs and reduce risk.
Specifying magnets early leads to more efficient designs, smoother installation and more reliable long-term results.
