We own advanced processing equipments and full set of production lines, products range can be as small as size class, 0.2 mm ~ 2.0mm, with high precision, tolerance between 0.005mm and 0.02mm. Also, we can make thickness 0.12 mm on very tiny thin ring like magnetic materials, using high electroplating technology like parylene coating and checkout equipment of projector and microscope to offer high and reliable products for our customers.

We have the ability to make small neodymium micro magnets less than 0.2 mm. Our tiny micro magnets have been used in many consumer electronics and medical applications. We carry many sizes of neodymium micro magnets in stock, but If you require a small, tiny neodymium micro magnet in a custom size, please contact us or use our online custom magnet quote form.

A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet commercially available.

Neodymium magnets are a composition of mostly Neodymium, Iron and Boron. If left exposed to the elements, the iron in the magnet will rust. To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated. There are a variety of options for coatings, but nickel is the most common and usually preferred. Our nickel plated magnets are actually triple plated with layers of nickel, copper, and nickel again. This triple coating makes our magnets much more durable than the more common single nickel plated magnets. Some other options for coating are zinc, tin, copper, epoxy, silver and gold. Our gold plated magnets are actually quadruple plated with nickel, copper, nickel and a top coating of gold. High Precise Magnets Rod Neo for Micro-Mechanical Devices
