Electrical Steel Coating for Bonded Lamination Stacks

We provide a broad selection of materials that have been qualified and validated through our processes, ensuring consistent compatibility with bonded stacking, curing, and high-speed motor operation.

Our material portfolio covers both electrical steels and special soft magnetic alloys, supporting a wide range of motor applications and performance requirements.

Electrical Steel

We provide a validated selection of non-oriented electrical steels, primarily sourced from leading Chinese steel producers, including Baosteel and Shougang, with whom we maintain long-term and close technical cooperation.

To ensure optimal performance for bonded lamination stacks, electrical steel sheets are coated in-house, specifically optimized for full-surface bonding processes. This approach enables:

All electrical steel grades are validated for dimensional stability, magnetic performance, and bonding compatibility prior to series application.

Soft Magnetic Alloy

For high-performance and special-duty motor applications, we provide a validated selection of special soft magnetic alloys, including cobalt–iron (Co–Fe) alloys, suitable for high magnetic saturation and high power density designs.

Supported thickness range:

Customer-Supplied Materials

In addition to our validated in-house material portfolio, customer-supplied materials are accepted for prototyping, sampling, and small-batch production.

Customer materials are evaluated and processed according to defined internal validation procedures to ensure compatibility with our stamping, coating (if required), bonding, and curing processes.

FAQs

Can I use my own materials?

Absolutely! We support production using customer-supplied materials. To ensure the final product's quality and performance, our technical team will evaluate whether your materials are suitable for the required processes and design specifications. If necessary, we can also provide professional advice or alternative material options to help achieve the best application results.

Do you sell materials?

We do not sell materials separately. Our core business focuses on manufacturing high-performance laminated rotors and stators while offering end-to-end solutions from design to production. The materials we use are carefully selected to meet the requirements of high-end fields such as aerospace, defense, and automotive, ensuring stability and reliability under various working conditions.

Can you apply coatings to my materials?

Unfortunately, we do not provide standalone material coating services. Our primary service is offering complete self-bonding rotor and stator solutions, including material selection and manufacturing. If you need related support, we can evaluate and advise within the framework of your project.

How do I choose the right materials for my project?

Material selection mainly depends on your project requirements and the motor’s operating frequency. Our experienced technical team will recommend the best material based on your specific application, considering both performance and cost. Don’t worry—we’ll ensure the materials meet your technical needs while staying within budget.

What material options do you offer?

We provide a wide range of material options, including different thicknesses and various alloy types. For specific material grades, please contact us directly. Our materials are suitable for diverse applications and meet the requirements of performance, cost, and processing techniques for different projects.
