Product Description

product name:   Alnico Magnets
Alnicos
are precipitation-hardened alloys requiring special heat treatment techniques. The raw materials 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 moulds. 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 600°C. 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.

Strong Cast AlNiCo Magnet

High quality Cast Alnico magnet

Cast Alnico 5 is the most commonly used of all the cast Alnico's .It combines high indications with a high energy product of 5 MGOe or more and is used extensively in rotation machinery, communications, meters and instruments, sensing devices and holding applications. The higher resistance to demagnetization(coercive force) of Alnico 8,cobalt content to 35%,allows this material to function well for short lengths or for length to diameter ratios of less than 2 to 1.
Sintered Alnico materials offer slightly lower magnetic properties butbutter mechanical characteristics than the cast Alnico materials.Sintered Alnico magnets are most suitable in small sizes(less than 1 oz.)in this process. The desired mix of metal powder is pressed to shape and size in a die,then sintered at 2300 F in a hydrogen atmosphere.The sintering process is well suited to large volume production,and results in parts which are structurally stronger than cast magnets.Relatively close tolerances can be achieved without grinding. alnico magnet, alnico magnets
