Find The Perfect Magnet

Alnico magnets can be composed of many materials including copper, titanium, nickel, cobalt and aluminum. A hard and brittle material, Alnico is known for sometimes being difficult to rework. You can have alnico manufactured in a number of shapes such as cylinders, horseshoes, blocks, discs, rings and rods. Alnico magnets have relatively high energies and high residual inductions and are manufactured through casting or sintering processes. 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. Sintering alnico results in a fine alnico powder that is then compacted in a press. Alnico magnets are able to resist extremely high temperatures, can keep their magnetic qualities for a long time period, in addition to these benefits they are also strong and affordable. The many benefits of using alnico magnets makes them a great choice for industrial and consumer applications..Strongest Magnet

Ceramic magnets are usually made from a chemical compound containing ceramic and iron oxide. Ceramic ferrite magnets are made using a process of pressing and sintering ceramic and magnetic powders. In sintering, two main materials are heated until they stick together. Described as being hard and brittle, ceramic magnets are affordable to produce.Although the terms hard and soft are misleading ceramic ferrite magnets are categorized as either being a hard ferrite or a soft ferrite. The difference between soft and hard ferrite magnets is in the intensity of the magnetic field required to de-magnetize the material . Hard ferrite needs a more intensive magnetic field than soft ferrite. Ceramic magnets are unique because they can be applied to flexible fabrics, making them ideal for decorative purposes, crafts and other usages in the home, school or work place. In actuality, there are a variety of different uses for ceramic ferrite magnets. Neodymium Magnets

Neodymium, a rare earth magnet, is made from the chemical element neodymium which has an atomic number of 60 and symbol of Nd. Present in the ore minerals monazite and bastnasite, neodymium is a silvery, soft metal that easily tarnishes. Neodymium magnets are preferred for certain applications because of their strength and ability to perform in extreme conditions. If you require maximum energy then neodymium magnets are a great choice. Neodymium is stronger than ferrite or alnico products. There are many advantages to using neodymium magnets and products made from neodymium. The major pros to neodymium are its strength, popularity, affordability and ability to perform in frigid conditions, however there are still some cons to using this rare earth magnet. A major con to using neodymium is that it can lose its magnetism in hot environments because of its low Curie temperature. However, on the flip side neodymium performs well in cold, frigid temperatures. Unlike samarium-cobalt, another rare earth magnet, neodymium is less resistant to oxidation which means it is ultimately not as durable and must have a surface treatment applied in order to protect the magnet from being scratched. 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..

Flexible magnet strips have multiple uses in a number of different industries. Using magnetism to work, when you place a magnet next to a ferrous metal or another magnet, the magnet will pull or attract the object using the force of magnetism. A magnet will attach itself to an object that it is attracted to due to the force of magnetism. No matter the field you are in, whether commercial, industrial, marketing or retail you will find many uses of magnets. Flexible magnetic strips are one of the most dexterous types of magnets. 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. In particular fridge magnets are a great advertising tool because they keep your company information in a prominent spot in the home. With a fridge magnet customers never have to search for your information..

Their durability makes block magnet a common industrial favourite. Depending on the need the composition of your block magnet will differ, which is why you must consider the conditions and purpose for the magnet before you make a decision. Rare earth magnets like samarium-cobalt and neodymium are stronger than alnico, ferrite or ceramic magnets, making them good choices for industrial applications where the magnet needs to able to handle heavy duty applications and uses. In addition to magnet strength, also consider whether you need your block magnet to perform well in extremely high temperatures. If so, then you will want to take that into consideration when choosing the magnet type, as different magnets lose or maintain their magnetism at different temperatures. When you make your choice about which magnet to use keep the use and requirements of the magnet in mind.
