Canadian Firm Releases More Information About Magnets

Aug. 1, 2011 - PRLog -- Alnico magnets can be composed of many materials including copper, titanium, nickel, cobalt and aluminum. Alnico is a hard and brittle material that can sometimes be difficult to rework. It is manufactured in a number of shapes, including blocks, discs, rings, rods, cylinders and horseshoes. Alnico magnets have high residual inductions as well as relatively high energies, and are usually manufactured in one of two ways, casting or sintering.

Processes where molten metal alloy is poured into a mold and processed through various heat-treated cycles is known as the casting process. When two main materials are combined and then melted to the point where they stick together is known as sintering, a common process used when manufacturing magnets. When sintering alnico a fine alnico powder is usually compacted using a press. Alnico magnets provide many benefits.

In addition to being affordable and strong they can also resist extremely high temperatures and they are able to keep their magnetic qualities for a long period of time. When it comes to industrial and consumer applications alnico magnets are a great option..

Ceramic ferrite magnets which are sometimes referred to as either ceramic magnets, ferrite magnets or ceramic ferrite magnets are one of the most popular types of magnets produced. The popularity of these magnets is due to their affordability and longevity.

Ferrite magnets are classified as a permanent magnet because they can keep their magnetic qualities for long periods of time. Since they are manufactured at low costs they are ideal to be used for a number of different uses wither in your garage, shop, at work or at home. A chemical compound that contains iron oxide and ceramic is the major composition for a ceramic ferrite magnet. Sintering and pressing mixtures of magnetic powders and ceramic is how ferrite magnets are created. Ferrite magnets are hard and brittle. Sintering is a method that is used to make objects from powder.

Sintering is finished off by heating materials in a furnace until the particles of powder stick to each other, but don't melt..

Neodymium, a chemical element with the symbol Nd and atomic number 60 is used to create the neodymium magnet, a rare earth magnet. Neodymium easily tarnishes in the air and is a silvery, soft metal present in the ore minerals bastnasite and monazite.

Preferred for certain applications, neodymium magnets are extremely strong and can perform in extreme conditions. If you require maximum energy then neodymium magnets are a great choice. Neodymium magnets are considerably stronger than ceramic ferrite or alnico magnets. Products that are made from neodymium have many advantageous features. Despite its strength, affordability and popularity neodymium does have a couple of drawbacks.

Unlike other rare earth magnets, such as samarium-cobalt, neodymium magnets have a low Curie temperature and as a result can't perform in high temperatures, which means that it could lose its magnetism in environments that are too hot. Neodymium is one of the few magnets that can perform very well in extremely cold temperatures. Neodymium is less durable and more prone to scratching than other rare earth magnets because it is less resistant to oxidation, which means that it must have treatments applied in order to protect it.

Neodymium can form cracks and easily corrodes because it is brittle, and as a result surface treatments of nickel, zinc, tin or gold are often applied as platings or coatings to protect the magnet. The problem of oxidation of neodymium magnets can be minimized by applying a plating or coating..

Magnetic strips that are flexible are used in many industries for a variety of purposes. Magnets use the force of magnetism to attract or pull an object towards or way from it. When the surfaces of the two objects touch, the magnet attaches itself to it. Whether you are in an industrial, commercial, marketing or retail field, you will find a number of uses for magnets.

Of all the types of magnets, flexible magnetic strips are the most dexterous. Flexible magnetic strips have a number of advertising purposes and can be used for labels, signage, point of sales displays and vehicle signs. Fridge magnets, printed magnets and planning boards all use flexible magnets. The refrigerator is the center of activity in your home which is why fridge magnets in particular are such a great advertising tool. With a fridge magnet, your customers never have to search for your contact information and can always be reminded of the service you offer..

Not surprisingly, block magnets are named for their rectangular block shape, although they do come in a variety of sizes and thicknesses. Block magnets are affordable and versatile and generally tend to be the type of magnet that people will think of. Used in many different settings like industrial and educational environments block magnets have many uses including recreational, decorative and . Block magnets are very customizable and are surprisingly affordable and easy to customize for your specific need.

The majority of magnet manufactures carry many magnets in stock but you can ask them to make you what you need affordably and quickly if what you want isn't in stock. It doesn't take long or cost a lot of money to have a magnet manufacturer customize a magnet for you.
