Silicon steel coil, also known as electrical steel or cold-rolled silicon steel, is a soft magnetic iron-silicon alloy containing 0.5%–4.5% silicon. It is primarily used to manufacture cores for motors, transformers, and inductors. The key performance requirements are low core loss (iron loss) and high magnetic permeability. Common grades include: 50W800, 50W1300, 35W270, 35W440, B50A470, B35A210, 23Q110, etc. In these designations, W stands for Non-Oriented (NO), while Q or R stands for Grain-Oriented (GO). Grain-oriented silicon steel (e.g., 23Q110) offers excellent magnetic properties along the rolling direction and is ideal for transformers. Non-oriented silicon steel (e.g., 50W1300) is isotropic and suitable for rotating machines.
Applications:
Motors: home appliances (air conditioners, refrigerators, washing machines), industrial motors, EV traction motors
Transformers: power transformers, distribution transformers, reactors
Small inductors: ballasts, relays, current transformers
Customer Common Terms & Abbreviations:
CRGO: Cold-Rolled Grain-Oriented steel
CRNGO: Cold-Rolled Non-Oriented steel
Core loss (iron loss): unit W/kg (e.g., P1.5/50 = 1.5 Tesla, 50Hz)
Magnetic induction: B50 (flux density at 5000 A/m)
Laminations: stacked core sheets
Annealing: heat treatment to relieve stress
Insulation coating: T2, T3, T4 types
Thickness specifications: 0.23mm, 0.27mm, 0.30mm, 0.35mm, 0.50mm
When placing orders, customers typically define technical requirements using grades (e.g., 50W1300 or 23Q110), CRGO/CRNGO, core loss values, and thickness.
