Uses for our Rare Earth block magnets:

To join anything to anything else is a compromise or a transaction. Fabrications usually separate at the joint. Like all compromises and transactions, costs apply. The very first joining task, attaching sharpened stone fragments to the end of wooden spears, came with significant compromises or transaction costs.

The spears took longer to make and were heavier, so our ancestral hunters carried fewer of them. Heavier to throw, the hunter would have to get even closer to prey increasing the incidence of flight or fight scenarios. If the stone tip dislodged for any reason, a blunt timber rod remained. All but useless for the rest of the hunt or against a counter-attack from injured prey. These transactional costs were paid in the hope that stone-tipped spears would result in better hunting and by extension, living standards, life expectancy and the quality of life. Relatively new to the fastening family, Magnets, are outperforming traditional fasteners like bolts, screws, rivets, nails and glues. The reasons are many but the main reason magnets will soon be acknowledged as the master fasteners of the Modern World is their introduction to Plastics.

Plastics of all kinds, manufactured in all kinds of ways, including 3D printing, are proliferating in industries across the world. The transaction costs or compromises of penetrative or adhesive fixing for plastic fabrications are too high. To fasten with a magnetic bond, however, is seamless, instantaneous and imposes no damage or degradation penalties to surfaces involved.

This particular unusually shaped magnet was custom-made for a fabricator in NSW who specialised in supplying the Mining sector.
