U shape AlNiCo magnets with holes

1.Product Introduction of U shape AlNiCo magnets

Alnico describes a family of materials, which is comprised of aluminum, nickel, cobalt and iron with varying additions of other elements. By varying the composition, it’s possible to tailor the magnetic properties to meet the needs of a wide variety of end users. There are two different manufacturing processes for Alnico: Cast Alnico can be made into many sizes and shapes, whereas Sintered Alnico is usually restricted to smaller sizes. Alnico products are widely used in all kinds of meters and other applications.

1.Q:Will magnets lose their power over time?
   A:Do lose a very small fraction of their magnetism over time. For example, SmCO magnet has been shown to be less that 1% over a period of ten years. 

2.Q:Can a magnet that has lost its magnetism be re-magnetized?
   A:If the magnet has not been damaged by extreme heat, it can be re-magnetized back to its original strength. 

3.Q:What are the standard industry definitions of "North" and "South" Pole?
   A:The North Pole is defined as the pole of a magnet that, when free to rotate, seeks the North Pole of the earth. Similarly, the South Pole of a magnet seeks the South Pole of the earth.

4.Q:Can a particular pole be identified?
   A:Yes, the North or South Pole of a magnet can be marked if specified. 

5.Q:What does "orientation direction" mean?
   A:Magnets have a “grain” in that they can be magnetized for maximum effect only through one direction. 

6.Q:Does stacking magnets together make them stronger?
   A:Yes, stacking two or more magnets together will act similar to a single magnet of the combined size. 

7.Q:Why are most neodymium plated or coated?
   A:Neodymium magnets are mainly constructed of Neodymium, Iron and Boron. Iron can oxidize very easily when exposed to moisture and will rust over time.
