Why Choose 50W800 Silicon Steel Coil?

Stable Magnetic Performance

The designation 50W800 indicates a nominal thickness of 0.50 mm with a maximum core loss of approximately 8.0 W/kg (50 Hz, 1.5 T). This balance between magnetic efficiency and material cost makes it suitable for general-purpose electrical equipment.

Good Punching Performance

The material offers good dimensional stability during high-speed stamping, helping reduce burr formation and extending die life. It is suitable for mass production of motor stator and rotor laminations.

Consistent Insulation Coating

Available with standard inorganic or organic insulation coatings, the coil provides reliable interlaminar insulation while maintaining good adhesion during stamping and assembly.
