Common shapes of 2 inch round magnets;
1. Standard round shape
2. With holes in the center or other locations, the holes are straight and screw holes.
In addition, some customers will ask for slots, additional backing, and steel shells (pot magnets) for salvage.
Material and magnetic strength of 2 inch round magnet;
Neodymium iron boron (NdFeB), the strongest magnetism, N35 to N55 optional, suitable for industrial adsorption, electronic equipment fixed.
Samarium cobalt (SmCo), high temperature resistance up to 350 ℃, magnetic strength is weaker than neodymium, winning in high temperature resistance.
Ferrite, low price, corrosion resistance, weak magnetic strength, suitable for the scenes that do not require high magnetic force.
Uses for 2 inch round magnets;
Some of the more common applications are magnetic levitation, such as magnetic levitation stereos, magnetic levitation potted plants, and magnetic levitation globes.
In salvage, it is also more common to salvage heavier metal objects underwater.
In magnetic door suction, it can be used as a magnetic closing device for garage doors.
Selection and precautions for 2-inch circular magnets
Need to choose the right material according to the application environment, you need to choose neodymium magnet for strong pulling force, and ferrite or samarium cobalt for high temperature environment. For humid environment, neodymium magnets need to be coated or plastic coated. Ferrite is the most cost-effective, neodymium magnet has good performance but high price.
2 inch round magnet price reference;
Normal 2-inch ferrite magnets with low price, usually within a few RMB. Neodymium magnets material are generally priced between a few dollars - tens of RMB depending on grade and thickness.
