Product Features

✅ SUPER STRONG MAGNETIC FORCE – Crafted from premium rare earth neodymium, these N52-grade magnets represent the strongest commercially available magnetic material today(See the table below). Despite their compact size, they deliver exceptional holding power, making them ideal for demanding applications where space is limited but maximum magnetic force is required.

✅ DURABLE NICKEL COATING – This magnet uses a three-layer nickel-copper-nickel (Ni-Cu-Ni) plating, which has excellent corrosion resistance and a smooth surface. The solid nickel coating protects the magnet well, making it somewhat resistant to moisture and oxidation even in wet or humid environments.

✅ SUITABLE FOR VARIOUS APPLICATIONS – From DIY projects and crafts to industrial uses, electronic assembly and precision model building. Strong permanent round magnets also excel in functional applications such as magnetic clasps, tool organization, secure fastening solutions and even innovative scientific experiments or art installations.

Support Customization

Hefei Super Electronics Co., Ltd. is a leading supplier of high performance NdFeB magnets, known for its high-quality products, comprehensive services and excellent customization capabilities.

We specialize in manufacturing customized premium magnets to meet industrial, commercial and technical applications. Our products are available in a variety of shapes, sizes and grades to ensure optimal performance in any use case.

1️⃣ Nickel (Ni-Cu-Ni) – The most common coating, offering corrosion resistance, durability, and a smooth metal surface. Good for general applications.

2️⃣ Epoxy – Excellent corrosion and wear resistance, ideal for wet or outdoor environments. Typically black.

3️⃣ Zinc (Zn) – A cost-effective coating that provides basic corrosion protection, but is not as durable as nickel or epoxy. Typically dark gray or blue.

4️⃣ Gold (Au) – Used primarily for decorative applications, gold coatings offer good conductivity and aesthetics.

1️⃣ Axial magnetization – North and South poles are on flat circular surfaces. Common in industrial, stationary and mounted applications.

2️⃣ Diametric magnetization – Poles are on the curved sides of a disk or cylinder, rather than on a flat surface. Commonly used in rotary applications and sensors.
