CRNGO Silicon Steel

CRNGO Silicon Steel (Cold Rolled Non-Grain Oriented electrical steel) is designed for electrical      applications that demand uniform magnetic properties in every direction. Unlike grain-oriented steel,      CRNGO is processed without directional grain orientation treatment, enabling stable performance in devices where the magnetic field rotates or changes direction—especially electric motors and generators.

As SHJISCO, we supply high-quality CRNGO silicon steel solutions focused on consistent magnetic behavior, strong processing stability, and efficiency-minded performance for modern electrical equipment manufacturing.

Product Family Map: Choose the Right CRNGO for Your Use Case

1) General CRNGO (Cold Rolled Non-Grain Oriented Silicon Steel)

This is the mainstream non-oriented electrical steel used across a wide range of rotating machines. Its isotropic magnetic properties make it suitable for stator and rotor core designs where flux direction varies continuously.

2) CRNGO for New Energy Automobile Motor (CRNGO for NEV Traction Motor)

A purpose-focused CRNGO solution for electric vehicle (EV/NEV) traction motors, where higher efficiency, lower loss at mid-to-high frequency, stronger mechanical performance, and high-speed stability can directly impact driving range and system reliability.

Quick Selection Guide

  • If your motor design prioritizes efficiency and lower heat: choose low-loss / high-efficiency CRNGO grades.

  • If your design targets compact size and high torque: consider super-induction style grade directions (high induction density).

  • If your rotor speed is high and mechanical stress is critical: prioritize higher-strength CRNGO options.

  • If your stamping/complex forming is demanding: select grades emphasizing formability and process robustness.

Key Magnetic Advantages: Built for Stable, Efficient Rotation

  • Isotropic magnetic properties: magnetic behavior remains consistent in all directions—ideal for rotating magnetic fields in motors and generators.

  • High magnetic permeability potential: supports efficient flux generation with reduced magnetizing force, enabling more compact and powerful designs.

  • Reduced core loss direction: engineered to lower hysteresis and eddy-current losses to improve efficiency and reduce heat generation during operation.

Mechanical & Processing Advantages: Friendly for Stamping and Complex Shapes

Electrical steel must perform not only magnetically, but also through real manufacturing workflows. CRNGO is widely adopted because it can be processed into intricate shapes while maintaining stable performance.

  • Excellent formability: suitable for stamping, punching, and forming complex motor laminations.

  • Easy to cut and shape: supports efficient mass production of lamination stacks and motor cores.

  • Mechanical strength & durability: supports long operating life under cyclical electromagnetic and mechanical loads.

Thickness & Frequency Considerations: Balancing Loss, Heat, and Robustness

Sheet thickness is a practical lever in CRNGO performance. Generally, thinner gauges help reduce eddy-current loss,which can improve efficiency and lower heat—especially valuable at higher operating frequencies. However, thinner materials can be less mechanically robust, so the optimal choice depends on your motor design, speed profile, and forming process.

  • Higher frequency / high-speed motors: often benefit from thinner gauge selections to control iron loss and temperature rise.

  • Heavy-duty mechanical stress: may require a strength-focused grade direction and a balanced thickness selection.

  • Manufacturing reality: stamping complexity and yield should be considered alongside purely magnetic targets.
