Vacuum annealing delivers clean, oxygen-free, and high-temperature processing-ensuring material integrity, surface quality, and optimal metallurgical properties for advanced applications.
Our vacuum heat treatment services support a wide range of critical applications. We process specialty alloys like NiFe, CoFe, pure iron, silicon steel, amorphous, and nanocrystalline materials with precision. This method ensures uniform heating, minimal contamination, and consistent structural transformation. With over 65 years of metallurgical experience, PML offers customized heat treatment solutions that enhance properties such as machinability, magnetic permeability, and mechanical strength. Our vacuum-based methods reduce oxidation, eliminate atmospheric interference, and support consistent results across batches.
