20kg - 50kg

Frenergy is an Australian owned online magnet supplier. We have worked hard to become one of Australia’s most trusted magnet retailers. Our product range is diverse and reflects the needs of our customers to have high quality magnets they can trust to perform. To assist our customers in finding the best magnet for their requirements we have put together a range of categories.
In this category there are magnets with a magnetic strength of between 20 - 50kgs. There are many shapes and sizes available in this range. Each shape or size has attributes that lend it particular relevance to different situations. Pot magnets are one of the most popular products we stock and they are well equipped for any holding application.

Neodymium magnets form the large majority of the magnets of this strength. Rare Earth magnets are able to achieve a superior hold compared to other permanent magnets of the same size. They have an amazing strength to size ratio. This means a smaller magnet can execute the same magnetic power as a much larger Ferrite magnet or Alnico magnet. In addition to their strength, Neodymium magnets also boast a diverse range of shapes, sizes and coatings.

Neodymium magnets and magnetic products

The few key drawbacks of Neodymium magnets have largely been overcome due to ingenious product design. Neodymium magnets are very brittle in nature and this means they are generally not available in large solid blocks. Instead Neodymium magnets are incorporated into larger magnetic tools and equipment if a broad magnetic grip is required.
Magnetic lifters and magnetic sweepers both incorporate magnets in a series to create a long or broad magnetic surface. Magnetic separator bars are another example of a product that has been cleverly designed. They use a number of magnets in combination to produce a far reaching magnetic field.

Heat has also long been considered Neodymium’s kryptonite however this is no longer the case. The standard N grade Rare Earth magnets are limited to 80oC operating temperatures. However there are now a number of alternative grades available. Previously Neo magnets would have begun to weaken once they exceeded this range with permanent loss of power sustained.
Neodymium magnets have now been developed to withstand temperatures of up to 200oC without risk of failure. Frenergy has a number of these high temperature grade magnets in stock. If you are after a specific size and a particular grade of magnet you may wish to place a custom order with us.

What are the best uses for magnets with a 20kg-50kg pull force?
At 20-50 kilograms in holding capacity, these magnets are becoming very powerful with the potential to cause injury if not handled correctly. We advise customers to review safe handling practices before using their magnets.
Fishing magnets are one of the most popular magnets in this range. They are pot magnets with specialty eyelet attachments that provide an easy point at which magnets or cords can be threaded.
Magnet fishing has become a popular pastime for many people in Australia and abroad. All sorts of ferrous metal treasures have been dragged up from the watery depths of lakes, canals and rivers. Fishing magnets are also popular for those who wish to clean up waterways by removing obstructions and sources of contamination. Trolleys, bikes and metal drums can be removed to enable a healthier marine environment.

The Pull Force listed for each magnet is based on lifting 10mm thick steel vertically. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around 30% of the pull force listed due to the effects of gravity and the lack of traction between the surface and the shiny magnet.
