The manufacturing process of 4J44 4J06 Soft Magnetic Alloy Strip involves several steps to ensure that it meets the highest standards for performance and reliability. Key stages include:
Melting and Alloying: The raw materials, primarily nickel and iron, are melted and alloyed to achieve the desired chemical composition.
Casting: After alloying, the molten metal is cast into ingots, which are then subjected to heat treatments to improve their uniformity and eliminate any impurities.
Rolling and Forming: The ingots are hot-rolled to form strips with precise dimensions. This step refines the material's grain structure and enhances its magnetic properties.
Annealing: To ensure optimal magnetic properties and ductility, the alloy strips are annealed at high temperatures, which relieves internal stresses and improves the material's performance.
Finishing: The strips are polished, cut to size, and subjected to final quality checks before being packaged for shipment.

High Efficiency: The excellent magnetic permeability reduces energy loss and improves the performance of electrical devices.
Durability: The strip maintains its properties over time, even under extreme temperature changes and mechanical stress.
Versatility: The alloy is adaptable for use in various industries, from aerospace to medical applications, providing reliable performance in demanding environments.
Competitive Pricing: Offered at a factory direct price, this alloy strip provides cost-effective solutions without compromising on quality or performance.
Precision: Manufactured to strict tolerances, ensuring consistent and reliable performance in precision applications.
