Product Details

Introduction:


Alnico are precipitation hardened alloys requiring special heat treatment techniques.The raw materials used are Cobalt, Nickel, Copper, Aluminum and Iron. Titanium, silicon,etc. are added in certain proportions.The raw materials in their purest form are melted in medium frequency induction furnaces and castings are made using conventional sand or shell mould.The heat treatment consists of heating the alloy in furnace to well above its curie-point, and holding it at that temperature for some time. This is followed by controlled cooling after which the castings are reheated and held for a long period at a temperature of about 600ᵒC. This ageing process increases the coercive force and the energy product. Finally, the castings are ground to obtain close dimensional tolerances whenever necessary and inspected for physical and magnetic accuracy.


Cast Alnico magnet is widely used in all kinds of sensors and meters, electronics, instruments, medical instruments, teaching, automobile, aviation, martial and other applic- ations.

                   Characteristics 



Compact crystal, high intensity

Good chemistry stability, strong anti-corrosion

Even elements, excellent and magnetic performance

Excellent temperature stability

Highest usage temperature reach 550°C



4.95x18.03mm-alnico-5-rod

                             Features:


An ideal material in high temperature applications, which has high operating temperature up to 550°C and above,  with excellent corrosion resistance. They can be partially demagnetized if they come in contact with other ferrous materials, special care is required during handling and storing.

Usually cast and grinded during production, they are available in various grades depending on its application. Others such as sintered Alnico have lower magnetic properties but offer higher mechanical characteristics
