Product Detail

NdFeB, the third generation of rare-earth permanent magnet, is the most powerful and advanced commercialized permanent magnet today. NdFeB has the high remanence, high coercive force, high-energy product and high performance/cost ratio, It can be formed into various sizes and widely used in many fields such as aviation, electronics, instruments, meters, machine, medical instrument and the like. It is especially suitable for the development of high-performance, compact and light products.
A variety of coatings can be applied to the NdFeB magnets' surface to overcome the principle drawback of neodymium-based magnets, their tendency to corrode easily.
SmCo is a high performance, low temperature coefficient permanent magnet with its high working temperature-350 degree centigrade. When working above 180 degree centigrade, its maximum energy product BH and steady temperature are superior than NdFeB magnetic materials. It needn't to be coated because it is difficult to be eroded and oxidized. SmCo magnet is widely used in motors, watch, transducers, instruments, positional detector, generators, radar communications, medical equipments, various magnetism spreading devices, magnetic processor, electrical engineering and magnetic derrick.
Hard ferrite (ceramic) magnets were developed in the 1960's as a low cost alternative to metallic magnets. Even though they exhibit low energy (compared with other permanent magnet materials) and are relatively brittle and hard, ferrite magnets have won wide acceptance due to their good resistance to demagnetization, excellent corrosion resistance and low price per pound. In fact, measured by weight, ferrite represents more than 75 percent of the world magnet consumption. It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.
Besides industrial application, Hard Ferrite magnets are widely use in Educational area.
Cast AlNiCo Magnet
General Introduction
Using patterns and simple moulding techniques, Alnico magnets can be cast to form a vast range of complex shapes and sizes at an economical cost
Eclipse Magnetics Alnico magnets are ideal for high temperature applications up to 550 degree.
Alnico is very stable, has good corrosion resistance and a typical hardness of 50 Rockwell C. Once cast, the material is so hard that the only machining possible is grinding
Cast Alnico represents the most versatile magnet material available. The range of properties can be accurately designed for specific applications by changes to element analysis and heat treatment.

Typical Applications
ABS braking system magnets

ABS braking system magnets

Reed switch operating magnets

Electricity meter damping magnets

Holding/clamping applications

Microwave applications

Weighing scale damping magnets

Electropermanent systems

Calibration magnets

Heat treatment jigs and fixtures
Rubber magnets are compound materials made by mixing ferrite magnet powder and rubber. Pressing or rolling makes the finished products. Because the material has good plasticity, the finished products or semi-manufactured goods can incise, stiletto, slit or back up other materials randomly, have good antisepsis and difficult demagnetization. The raw materials are plentiful, so the price is lower. Rubber magnets are natural rubber magnets or isomer rubber magnets. Natural rubber magnets have weak magnetism, are used on iceboxes, presswork and marketing and promotion premiums. Isomer rubber magnets have strong magnetism, and are used in such applications as micro-motors and magnet toys.
What are the uses of the magnets? Let us find the answer as below:
Locate metal studs in a wall Seal off air-conditioning vents to improve home heating by placing vinyl-coated sheets over the steel register faces
Hang Polaroid of projects-in-process on the lip of a metal shelf above the workbench Collect nails from a porch repair job that have fallen in the grass
Prevent corrosion inside your water heater; a magnet placed on the freshwater intake pipe catches damaging metallic calcium particles before they can get inside Pin blueprints onto the side or hood of the truck
Create a bulletin board without the use of tacks, tape, or hooks on walls coated with magnetized? paint containing metals
Protect a tractor engine: Ceramic magnets placed in the oil pan will attract steel bits that get into the oil from grinding pistons
Fasten steel framing squares to the outside of toolboxes for quick access by gluing magnets to the box sides
Clean up metal shavings that have fallen from the bench grinder onto the workshop floor
