High-Quality Ferrite Core Magnetic Materials for Efficient Welding - China Suppliers & Factory
Product Feature
High Magnetic Permeability & Strong Flux Concentration
Superior manganese-zinc ferrite material has outstanding magnetic permeability which can concentrate magnetic flux density inside the induction coil and minimize magnetic reluctance. In this way, the energy is focused on the weld seam.
Low power loss & efficient energy conversion
The ferrite material reduces eddy current and hysteresis losses to some extent, making energy consumption more efficient and induction heating more stable.
Durable Construction for Industrial Environments
With high density and thermally stable construction, the ferrite rod has higher mechanical strength and durability in continuous high-speed welding conditions.
