subject: Buy A Custom Magnet, Even Rare Magnets Are Customizable [print this page] When its time for you to purchase magnets for what ever use you need them for you have got a wide range of products and configurations from which to select. The 3 primary varieties of magnets are permanent stock magnets, flexible magnets, and rare earth magnets. Lets do a lowdown on each basic magnet types to be able to have a simple presentation of what each is effective at.
Permanent stock magnets would be the family which is most often employed. The most popular of all of these is the rather familiar alnico magnet in the horseshoe shape. They've also been available in rods or cylinders. The alnico is superb for high temperature applications since it's service temperature limit is 525 degrees Celsius. It is not easy metamorph because it is tough and brittle. The other variety is channel and base assemblies. This is usually a very broad family of magnets that make use of a magnet plus a steel cup or channel. They can be very adaptable in their uses, and ideal at holding and positioning. They will all feature mounting holes that will let the magnet to be secured using a screw or bolt in a mounted position.
Flexible magnets are the ones you will be familiar with if you have magnets on the freezer or fridge. These are commonly utilized for decor and may have one side laminated in vinyl for printing on. They come slim enough that they'll be placed through ink jet printers, while plumper variants could be the option for vehicle signage. Every one has the option for getting silk screened, die stamped, pad printed and hot stamped. Additional options consist of dry erase, cut to length, high speed kiss-cutting, laminating and punching. A higher energy flexible strip magnet can be readily available for purposes which need a more significant magnetic power. These stronger magnets would have the same choices for printing as the ordinary selection.
There are two main types of rare earth magnets.The weakened of the two is samarium cobalt. It may be less strong, yet it does really well in hot temperature environments. Additionally it is a more costly selection and is normally only used when it's necessary to possess a greater resistance to high temperature sources. They are usually made into smaller blocks and discs, but rings and big blocks are also offered. Neodymium magnets are the most effective magnets available. These are the only solution when maximum energy is required. They're normally nickel coated to protect their brittle nature and are available in blocks, discs and rings. The maximum service temperature is usually around 125 - 150 degrees Celsius.
These are the most basic magnets currently available. Other choices include tool specific magnets and there are a whole variety of options available for unique jobs. Both these magnet types would be best dealt with in their own articles as each one has several versions. If you have needs not met by these simple magnet types you may want to examine the tailor made options with a reliable vendor next time you buy magnets.
