Detailed Product Description

AlNiCo Aluminum-Nickel-Cobalt Magnet Cast AlNiCo Cast Alnico magnets, which are aluminum nickel-cobalt-iron alloys, are the most established and widely used permanent magnet materials. Because of their high flux density and superior temperature stability, cast magnets have been accepted in the widest range of application. Application: Speaker Telephone Mobile Odometer Eletricitymeter Watermeter Eletricity Motor Switch Adhesion Sensors Sintered AlNiCo In comparison with other permanent magnet materials, the sintered alnico magnet products are characterised by:1. Fine crystalline metallic structure; 2. Very high temperature stability; 3. Good corrosion resistance; 4. High mechanical strength. Alnico describes a family of materials, which is derived from a common base composition comprising of aluminum, nickel, cobalt and iron with varying additions of other elements. By varying the composition it is possible to tailor the magnetic properties to meet the needs of a wide variety of end use applications. 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. However, both processes are not suitable for complex geometry and configurations, both alloy systems are hard and brittle and do not lend themselves to conventional machining. Standard Sintered Alnico has tighter dimensional tolerances due to its processing. It also has slightly lower magnetic properties, but better mechanical strength than Cast Alnico products. Alnico alloys, which possess the lowest reversible temperature coefficient magnetism in permanent magnet materials, have excellent working temperature up to 600 celus degree. High Nickel content of Alnico alloy result in good stability against corrosion and oxidation, this metallic composition is also a good electrical conductor. Advantages for using Alnico: Excellent temperature characteristics Capable of working at a wide range of temperature up to 5500C High field strengths at medium prices Easy of magnetizing Compatible with most painting or plating systems(includingnickel and copper)
