Products Overview
This high quality tile magnet depends on how it's manufactured and paired. It is shaped with a curved surface and appears to be precision-machined and possibly coated with Ni-Cu-Ni (nickel-copper-nickel) or another protective coating to prevent corrosion.
Magnet Type:
v Material: NdFeB (Neodymium Iron Boron)
v Grade (likely): N35–N52 depending on strength and heat resistance needs
v Shape: Arc or semi-elliptical block
v Coating: Likely nickel or epoxy for protection
1.1 Common Application:
This high quality tile magnet characterized by their curved shape and strong magnetic properties, are widely used in various applications, particularly in electric motors and generators. They are also found in medical devices, robotics, and industrial automation equipment. Their ability to generate a strong magnetic field with a reduced air gap between the magnet and the stator contributes to improved motor performance.

Operating Conditions and Reliability
The long-term performance of NdFeB magnets is highly dependent on operating conditions such as temperature, humidity, magnetic circuit design, and environmental exposure. Proper material selection ensures stable magnetic performance throughout the product's service life.
3.1 Temperature Performance
Maximum Operating Temperature:
Varies by grade, typically ranging from 80°C to 220°C
Curie Temperature:
Generally between 310°C and 380°C
Temperature Grade Classification:
N: Standard temperature applications
H / SH / UH / EH / AH: Medium to high-temperature and high-reliability applications
By alloying with elements such as Dysprosium (Dy) or Terbium (Tb), the magnet's coercivity and thermal stability can be significantly enhanced.
3.2 Humidity and Corrosive Environment Resistance
Through appropriate surface coating selection, NdFeB magnets can be adapted for:
High-humidity environments
Coastal or salt-laden atmospheres
Mild chemical exposure conditions
Coating selection should be based on actual operating environment to ensure long-term corrosion protection.
3.3 Long-Term Magnetic Stability
Under recommended operating conditions:
NdFeB magnets exhibit extremely low annual demagnetization rates
Magnetic performance remains stable over extended service periods
When operated within specified temperature limits and with proper magnetic circuit design, long-term continuous operation can be reliably achieved.

Application & Environmental Considerations
Avoid exposure to high temperatures beyond the specified operating limit.
Do not machine, cut, or grind magnets without proper safety controls.
Use protective coatings carefully; damaged coatings may lead to corrosion.
Keep magnets away from children to prevent swallowing hazards.
Follow proper magnetic shielding requirements during transportation and use.
FAQ
Q1: Why are NdFeB magnets prone to corrosion?
Answer:NdFeB material is chemically active and inherently not corrosion-resistant. Corrosion protection depends heavily on surface coating quality, coating thickness, and the operating environment.
Q2: How should I choose between nickel, zinc, or epoxy coatings?
Answer:Nickel plating (NiCuNi): Good appearance and general-purpose use
Zinc plating: Lower cost, suitable for dry environments
Epoxy coating: Best corrosion resistance for humid or harsh conditions
Q3: What is the maximum operating temperature of NdFeB magnets?
Answer:This depends on the grade, not the magnetic strength alone.
Standard N grades: up to ~80°C
High-temperature grades (H, SH, UH): up to 150–180°C or higher
Exceeding the limit can cause irreversible demagnetization
