Controlled heat treatment using dry hydrogen to enhance magnetic properties and structural integrity of components for critical applications in electronics, automotive, aviation, defence and healthcare industries.
Our heat treatment process is designed to improve magnetic permeability and structural stability. Using dry hydrogen and/or nitrogen atmospheres, we tailor thermal cycles to meet demanding magnetic performance requirements. Each material type undergoes a custom heat cycle developed by our experts, ensuring optimal grain growth, impurity removal, and mechanical consistency. These cycles are executed after final fabrication for best results.
Raise the temperature to the required level for structural and magnetic refinement
Hold the material to purify it and optimize its microscopic magnetic structure
Cool the component in a regulated manner to lock in the desired magnetic performance
Adjust soak and cooling times based on material and geometry, typically resulting in 20–35 hour cycles
Use high-purity dry hydrogen and/or nitrogen furnaces to prevent oxidation, carbon pickup, and grain boundary issues
Nickel Iron Alloys: Improves permeability and magnetic performance for shields, cores, and flux concentrators.
Silicon Iron: Enhances magnetic properties for efficient automotive and energy applications.
Material Softening: Reduces hardness without oxidation for easier machining and assembly.
Component Demagnetizing: Removes residual magnetism for precision electronic and industrial components.
PML operates 20 fully controlled furnaces capable of processing components of various shapes and sizes with class 2 type accuracy (±6°C)
Each furnace uses calibrated PID, Thyristor, and programmable controllers to precisely follow tailored heat treatment profiles
Our data loggers ensure continuous recording of treatment parameters, and all cycles are archived and traceable for quality assurance
Magnetic properties are validated post-treatment using Hysteresis Loop plotters. Exclusive annealing fixtures optimize furnace space, while cleaning, degreasing, and preheating lines ensure readiness before processing
Every cycle is backed by the expertise of PML’s metallurgists and tailored per the material and industry standards
It’s used to purify metal components, improve grain structure, and enhance magnetic properties while preventing oxidation or carbon pickup
