about SHUNGE STEEL

Shunge Steel was established in 2008, located in the South China lron and Steel Marketing Lecong, Shunde District, Foshan City, the largest steel distribution center in China . We are a service-oriented comprehensive company integrating silicon steel trade, processing and distribution. We supply high-grade non-oriented silicon steel with thickness as low as 0.1mm, tailored for use in high-precision applications such as robotics and drones.

Ultra-thin non-grain oriented electrical steel

Ultra-thin non-oriented electrical steel is a special silicon steel material with a thickness significantly lower than the conventional standard, typically referring to cold-rolled non-oriented silicon steel thin strips with a thickness ranging from 0.10mm to 0.20mm. Its core value lies in significantly reducing high-frequency eddy current losses through ultra-thin design, while also maintaining high magnetic permeability and high strength, to meet the strict requirements of high efficiency and lightweight for high-end equipment such as eVTOL (Electric Vertical Takeoff and Landing) motors and humanoid robot motors.

Our Industry Application

eVTOL Electric Motor，humanoid robot Motor，New energy vehicle Motors.

eVTOL Electric Motor

Cars and motorcycles: Many traditional cars and motorcycles use lead-acid batteries as starting batteries, but replacing lead with lithium batteries can provide better performance and experience. Lithium batteries have higher energy density and faster charging speed, as well as lower self discharge rate and longer service life, making them an ideal substitute for automotive and motorcycle batteries.
