Frequently Asked Questions

Neodymium rectangle magnets (also called block magnets) are widely used for clamping, holding fixtures, sensors, automation systems, and magnetic circuits. Their high pull force in a compact size makes them ideal when maximum strength is needed in limited space.

Neodymium rectangle magnets provide the highest magnetic strength, making them ideal when maximum pull force is required in compact spaces. Samarium Cobalt (SmCo) rectangle magnets, while not as strong, offer exceptional resistance to high temperatures and corrosion, making them better suited for harsh environments.

Yes. Rectangle magnets distribute force across a flat surface, making them well-suited for mounting, magnetic assemblies, and linear motion systems. Engineers often choose them when even force or compact alignment in assemblies is more important than rotational symmetry.

The best size depends on your application, but engineers often start with common stock sizes such as 10 × 5 × 2 mm or 20 × 10 × 5 mm, since they balance strength and ease of handling. Thin rectangles (1-3mm) are popular in compact electronics and sensing. For early testing, standard neodymium grades (N35–N52) allow quick evaluation before moving to custom dimensions.

We provide a wide range of coatings to match different applications. Common options include nickel and rubber. Nickel is the standard for durability and rubber coatings improve grip and impact protection. Additional specialty coatings are also available depending on your requirements.

Yes. Through our engineering division, SM Magnetics, we can design and manufacture custom sizes, magnetization directions, and specialized coatings. You can either submit a custom request form or contact us directly to speak with our experts.
