PRLog - July 19, 2011 - OAKVILLE, Ontario -- 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. Alnico can be manufactured in many different shapes, the most popular being blocks, rings, discs, rods, horseshoes and cylinders .
With high residual inductions and high energies alnico magnets are normally manufactured through sintering or casting. Casting processes involve pouring molten metal alloys into a mold and then processing it through cycles that are heat-treated.
Manufacturing magnets through sintering is a process where two main materials are combined and melted down until where they stick to each other. When it comes to sintering alnico a fine alnico powder is often 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. Alnico magnets are excellent choices for industrial and consumer applications.
One of the most popular types of magnets are ceramic ferrite magnets, also known as ferrite or ceramic magnets. Contributing to the popularity of ferrite magnets is their affordability and ability to maintain their magnetic qualities for long periods of time.
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. Ferrite magnets are made from a chemical that contains iron oxide and ceramic.
Ceramic ferrite magnets are made by sintering and pressing mixtures of magnetic powders and ceramic.
Ferrite magnets are hard and brittle. Sintering is a method that is used to make objects from powder. The sintering process is completed by heating the materials in a furnace (but not to their melting point) until the particles of powder stick to each other.
The strength and affordability of neodymium makes it one of the most popular rare earth magnets. Rare earth magnets generally are strong and are permanent magnets, which means they hold their magnetism for a long period of time.
Rare earth magnets are the strongest type of permanent magnet currently made, although they were developed in the 1970s and 1980s. The alloys of rare earth elements such as iron, cobalt and nickel primarily comprise rare earth magnets.
Rare earth magnets often have a plating or coating applied to them to protect them from chipping or cracking since they are so brittle and more vulnerable to corrosion.
The two types of rare earth magnets are Neodymium and Samarium-cobalt. The strongest of all permanent magnets is neodymium, which is even stronger than alnico, samarium-cobalt or ferrite magnets.
The term rare earth magnet is misleading, in fact neodymium is not made of rare elements at all, it is composed of common elements like boron, iron and neodymium which are commonly found and is why neodymium is not expensive to produce.
Neodymium magnets have many common uses which is why they are found in fields like mechanics, electronics, health and security.
There are many uses in a variety of industries for flexible magnetic strips. When you place magnets next to another magnet or a ferrous metal it will pull or attract that object by using the force of magnetism.
A magnet will attach itself to an object that it is attracted to due to the force of magnetism. The uses for magnets are wide and which is why they are often used in fields such as industrial, marketing, commercial and retail. Flexible magnetic strips are extremely dexterous.
The advertising uses of flexible magnetic strips are numerous and include purposes designed for labels, vehicle signs, signage and point of sale displays. Planning boards, fridge magnets and printed magnets are made using 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.
Block magnets are available in many different thicknesses, widths and sizes although they are generally rectangular in shape. Most people who think of a magnet think of a block magnet because it is such a popular choice in many different settings, it is not only affordable but also versatile.
Block magnets are useful in a number of different environments, including for industrial, educational, recreational, decorative and therapeutic uses. The composition of block magnets varies depending on your needs, they are a very flexible magnet and are easy and affordable to customize.
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. Having a block magnet customized to your needs can be done for a reasonable price.
