CRNGO (cold-worked non-oriented electrical steel) is the core material of motors, transformers and other equipment. Its low iron loss and high magnetic permeability make it have important application value in the field of small household appliances.

Mechanical Properties

Scope of Application

①Transformer: high end transformer: 750kV, 1000kV

②Medium and low-end Transformers: 220-500kV, 110-200kv, less than 110kV

③Energy saving transformer of various grades: 0.18-30mm

Brand Comparison

Material advantages and technical characteristics

1. Optimization of magnetic properties

The silicon content is controlled at 2%-3%, and a uniform grain structure is formed through cold rolling and annealing processes to improve magnetic permeability and reduce hysteresis loss.

Surface insulation coatings (such as inorganic coatings) can reduce eddy current losses and improve motor efficiency.

2. Processing and durability

The thickness tolerance is small (±0.01mm), which is suitable for precision stamping and meets the complex structural requirements of small household appliance motor cores.

High mechanical strength reduces vibration noise during equipment operation and extends service life.

3. Economic analysis

Initial cost: The purchase price of high-performance models (such as 35W210) is about 7,200 yuan/ton, which is higher than ordinary steel, but the improvement in energy efficiency can reduce long-term electricity costs by more than 30%.

Long-term benefits: Taking air-conditioning compressors as an example, the use of 35W230 motors saves about 120 degrees of electricity per year compared to 50W1300 motors, and the material price difference can be recovered in 3 years.

Match models on demand

1. Low-load scenarios (such as small fans): 50W1300 is preferred to balance cost and basic performance.

2. Mid-to-high-end equipment (such as variable-frequency home appliances): 35W230 or 35W210 is recommended to enhance product competitiveness through energy efficiency improvement.
