Not only 1-inch magnets are popular, 2-inch magnets are also often used by customers. Today, this article will introduce 2-inch rare earth magnets in many ways, including types, shape types, and purchasing suggestions.
2-inch rare-earth magnet (about 50.8 mm) usually refers to a strong magnetic material made from rare-earth elements, mainly including two types of neodymium-iron-boron (NdFeB) and samarium cobalt (SmCo).

In these 2 kinds of rare earth magnets, neodymium material is more magnetic, but poor temperature resistance, samarium cobalt material has less magnetic energy than neodymium, but good temperature resistance and strong corrosion resistance.
2-inch rare earth magnets in common shapes；
Disc magnets (standard disc shape)
Ring magnets (with hole in the center for mounting)
Square/Rectangular Magnets (for specific equipment installations)
Arc magnets (commonly used in motors and generators)
2-inch rare earth magnets Main applications;
It is widely used in the fields of motors and generators, industry and manufacturing, magnetic levitation and transportation, defense and aerospace, research and education, electronics and consumer products.
Buying Advice;
First of all, you need to confirm the application environment, if there is a high magnetic force in the room temperature environment need to choose neodymium iron boron, more than 200 degrees Celsius above the high temperature environment choose samarium cobalt.
As for plating, nickel plating is wear-resistant, epoxy resin can insulate, gold plating is suitable for decoration and luxury goods.
Adsorption of flat objects suggested round, need to fix or through some parts suggested ring, such as countersunk holes, through-hole type.
Square rectangle can provide larger contact area. Special processing is also available to fit the application.
