Ferrite magnets are a common and widely used magnet material, with several different grades based on magnetic strength. Y30 and Y35 are two commonly chosen grades, What is the difference between Y35 magnet and Y30 magnet? Please click here to know more：Ferrite (Ceramic) Magnet grades

What is a Y30 magnet?

Ferrite C5 is also known as Y30. Most ferrite magnets are known either by their C names or by the newer Y names. Other names exist for ferrite grades e.g. HF26/18 (which is Y30) but this is a European naming convention and is not commonly used outside mainland Europe. 

What is a Y35 magnet?

Y35 describes the grade of the magnet material used for ferrite magnets, according to the Chinese Standard SJ285-77. This is a common standard in China that we use as well. The exact physical values can be found in the table Physical magnet data. There are various standards for the physical features of ferrite magnets.

The difference between Y35 magnet and Y30 magnet: 

Magnetic strength: Y35 magnets have a higher magnetic strength than Y30 magnets of the same size, meaning they can produce a stronger magnetic field and attract heavier objects. The magnetic energy product of Y30 magnets is around 26-30 MGOe, while Y35 magnets have a magnetic energy product of 33-37 MGOe.

Magnetization intensity: Y35 is a high-grade ferrite magnet, similar to the N48 and N50 grades of neodymium magnets, with higher performance than Y30. As such, it is less commonly used. Compared to Y30, Y35 has a higher magnetization intensity.

Density: Y35 magnets have a higher density, typically ranging from 5.0-5.4 g/cm³, while Y30 magnets have a density of 4.7-5.1 g/cm³.

Thermal stability: Y35 has better thermal stability, meaning it can maintain magnetic strength and coercivity more effectively at higher temperatures.

Price: Due to Y35's higher magnetic strength, density, and thermal stability, it is generally more expensive than Y30.

These are the main differences between Y30 and Y35 ferrite magnets, and users can select the appropriate grade based on their specific application needs. In most cases, Y30 should suffice.
