Heat Resistant Cube Magnets

Its satin-textured surface reflects a quiet authority, like a knight armored not for show, but for unshakable duty.

Born from the rare earth aristocracy-Neodymium Iron Boron (NdFeB)-this precision engineered heat resistant cube magnet is compact in form but immense in force.
With astonishing magnetic pull embedded in every millimeter, it draws heavy metals as if guided by unseen gravity. Whether in precision motors, high-end sensors, or rigorous automation systems, it performs with unwavering consistency, guarding the rhythm of power with unseen hands.

Heat-resilient, corrosion-resistant, and enduringly strong-these are its basic virtues.
High consistency, exceptional energy density, and minimal magnetic loss define its excellence.
It does not boast, yet proves its worth in silence, quietly declaring:
"I may be small and still, but I move the world."

• Product Name: heat resistant cube magnets
• Magnet Grade: N45 (Br ≥ 14.8 KGs, Hcj ≥ 10.5 KOe) - Customizable

• Dimensions: L12 x 10×3 mm
• Tolerance: ±0.05 mm (Length, Width, Thickness)
• Operating Temperature: ≤ 80°C (Customizable high-temp versions available)
• Density: ≥7.5 g/cm³

• Magnetic Flux: 2.2 mWb (Measured; value varies by material grade)

N45 is a commonly used grade of neodymium iron boron (NdFeB) permanent magnet, offering a good balance between magnetic strength, stability, and cost. It provides high magnetic energy density and strong magnetic force, making it suitable for a wide range of industrial applications. N45 magnets are widely used in motors, sensors, magnetic assemblies, and automation equipment. With standard temperature ratings, N45 is typically recommended for operating environments up to about 80 °C unless higher-temperature grades are specified

Dimensional inspection is performed using calibrated measuring instruments to verify tolerance compliance.

Magnetic performance testing confirms conformity with the specified material grade.

Visual and surface inspection checks coating integrity, appearance, and mechanical defects.

Final quality inspection is completed prior to shipment to ensure product consistency and reliability.

 

Magnetic Performance Testing

Magnetic properties are measured to confirm conformity with design specifications:

Residual Flux Density (Br)

Coercivity (Hcj / Hcb)

Maximum Energy Product (BHmax)
Testing is conducted using hysteresis graphs and flux meters to ensure stable magnetic output and batch consistency.

Dimensional & Appearance Inspection

Precision dimensional measurements are carried out using calipers, micrometers, and optical measuring systems. Surface quality is inspected to detect cracks, chips, or coating defects that may affect performance or assembly.

• Conduct final quality inspection before packaging to confirm compliance with order requirements.
• Apply corrosion protection suitable for long-term storage and overseas transportation.
• Isolate magnetic fields using spacers and shielding materials to minimize attraction force.
• Secure magnets in rigid inner boxes to prevent shifting during transit.
• Use strong outer cartons or wooden cases, depending on shipment weight and magnetic strength.
• Affix international shipping labels, including "Magnetized Material" and handling symbols.
