0.35–0.50mm Non-Oriented Silicon Steel Coil 35WW230–50WW1300 with 914–1250mm Width and 508mm/610mm Coil ID for Motor and Electrical Applications

１．Product Overview

Non-oriented silicon steel coils are cold rolled electrical steel products designed for electromagnetic applications including motors, generators, transformers, compressors, and electrical equipment.

The product combines controlled thickness, stable magnetic performance, and consistent surface quality for punching, laminating, and high-speed motor core production. Grades from 35WW230 to 50WW1300 support different iron loss and magnetic flux density requirements for industrial electrical systems.

２．Technical Solution

The silicon steel coils are manufactured through cold rolling and electrical steel processing technology to achieve controlled magnetic properties and dimensional consistency.

Non-oriented grain structure allows magnetic flux distribution in multiple directions, making the material suitable for rotating electrical machinery. Thickness ranges from 0.35 mm to 0.50 mm help reduce core loss while maintaining mechanical stability during punching and stacking operations.

Waterproof paper, metallic envelope wrapping, and steel strip fastening are used to improve transportation protection and storage stability.
