Choosing the right type of magnet

Choosing the right type of magnet - Magnetyz

Choosing the right type of magnet is essential for performance, durability, and cost-efficiency.

Here’s a quick guide to help you choose the best magnet for your application:

1. Neodymium (NdFeB) Magnets – Super Strong

Best for: High-strength needs in compact spaces
Strength: ★★★★★
Max Temp: 80°C to 200°C (depending on grade)
Common Uses: Electronics, Motors, Magnetic locks, Tools, Packaging, Sensors

Strongest type of permanent magnet

Grades range from N35 to N52 with suffix M to EH for High Temperature Capacity

⚠️ Note: Brittle and prone to rust – usually coated. (NiCuNi, Zn, Black Epoxy)

2. Ferrite (Ceramic) Magnets – Cost-Effective

Best for: General-purpose, low-cost applications
Strength: ★★☆☆☆
Max Temp: Up to 250°C
Common Uses: Fridge Magnets, Toys, Crafts, Speakers

Low-cost and rust-resistant

Brittle, but great for mass-market use

Grades like Y30 (C5) and Y35 (C8) are most common

3. Samarium Cobalt (SmCo) Magnets – Heat & Corrosion Resistant

Best for: High-temperature ( Up to 350°C) and harsh environments
Commonly used in Aerospace, defense, high-temp motors

4. Alnico Magnets – High Temperature Stability

Best for: High-temp and precision instruments can hold upto 500°C


How to Choose the Right Magnet:

  Requirement Recommended Magnet
Maximum strength Neodymium 
Budget-friendly Ferrite Magnets
High-temperature use Samarium Cobalt or Alnico
Corrosion resistance
Samarium Cobalt or Ferrite
Musical instruments Alnico

Final Tips:

Size and shape matter – a stronger magnet isn’t always better if it's too large.

Coating is important for neodymium to prevent rust.

Consider magnet grade based on strength and temperature needs.
