Product Description
Silicon Steel Narrow Strip Coil
Product Introduction
Our Silicon Steel Narrow Strip Coil represents the pinnacle of precision and efficiency in soft magnetic materials for modern electromagnetic applications. Engineered from high-grade, grain-oriented or non-oriented electrical steel, this product is cold-rolled and slit to exacting narrow widths to meet the demanding requirements of compact, high-performance electromagnetic components.
This coil-form material is specifically designed for applications where space optimization, design flexibility, and superior magnetic performance are paramount. It serves as the essential core material, guiding and concentrating magnetic flux with minimal energy loss. By providing material in a convenient coil format, we enable automated, high-speed production processes for manufacturers, significantly enhancing production efficiency and material yield. From miniature transformers and high-efficiency motors to specialized inductors and sensors, our Silicon Steel Narrow Strip Coil is the intelligent choice for engineers pushing the boundaries of electromagnetic device miniaturization and performance.
Product Parameters
Parameter Category Specification Details
Core Material High-Grade Non-Oriented Electrical Steel (e.g., 35 Series, 50 Series) or Grain-Oriented Electrical Steel (GOES). Custom grades available.
Thickness Ranging from 0.20mm to 0.50mm (standard), with tighter tolerances upon request (e.g., 0.35mm ± 0.02mm).
Width (Slit) Precision-slitted to widths from 5mm up to 150mm, with a standard width tolerance of ±0.1mm.
Coil Dimensions Inner Diameter (I.D.): 200mm, 300mm, or 405mm (standard). Outer Diameter (O.D.): Customizable, typically up to 1000mm. Coil Weight: Tailored to customer needs.
Magnetic Properties Core Loss (W/kg): Low specific loss values at 1.5T/50Hz or 1.7T/400Hz (e.g., W15/50 ≤ 2.0 W/kg for premium grades).
Magnetic Induction (T): High saturation induction, B50 ≥ 1.70 T (NOES) or B800 ≥ 1.85 T (GOES).
Surface Insulation High-quality, inorganic or semi-organic insulation coating (C-3, C-5, or C-6 type). Provides excellent interlaminar resistance, corrosion protection, and weldability.
Packaging Securely wrapped with moisture-resistant material, reinforced edges, and clearly labeled for safe transportation and storage.
Product Advantages
  • Enhanced Performance & Design Freedom
    The use of premium silicon steel ensures extremely low core loss and high magnetic permeability, directly translating into higher efficiency, cooler operation, and increased power density for your final electromagnetic devices. The narrow strip format allows for innovative core geometries (like toroidal or custom shapes) that are impossible with standard wide sheets.
  • Optimal Cost-Efficiency & Yield
    Supplied in coil form, our narrow strip minimizes scrap generation during your stamping or winding processes. The precision slitting ensures consistent width, eliminating the need for secondary trimming and maximizing material utilization, which significantly reduces your total production cost.
  • Production Flexibility & Speed
    The ready-to-use coil format is perfectly suited for automated, high-speed progressive die stamping or continuous winding machines. This streamlines your manufacturing line, increases throughput, and reduces labor costs compared to handling sheet stock.
  • Superior Consistency & Reliability
    We maintain rigorous control over material properties, gauge, and slit width tolerances throughout the entire coil. This batch-to-batch consistency guarantees predictable performance in your products, leading to higher reliability and quality. The durable insulation coating further ensures long-term stability and performance.
