Permalloy 1J79 Hydrogen Annealing Furnace

Permalloy 1J79 Hydrogen Annealing Furnace

A specialized high-vacuum hydrogen annealing solution designed for Permalloy, 1J79, Pure Iron, and vacuum electronic devices. By combining deep vacuum degassing with multi-level safety interlocked hydrogen control, it effectively removes impurities and significantly boosts magnetic permeability, ensuring products meet rigorous magnetic and vacuum sealing standards.

Product Overview


Developed for the extreme purity requirements of magnetic materials and electronic vacuum devices. Featuring a fully sealed 310S heat-resistant stainless steel muffle tank, integrated with multi-stage vacuum pumps (Diffusion/Molecular) and a pure hydrogen atmosphere. At processes up to 950°C, it effectively removes impurity atoms like Carbon and Oxygen, achieving a leap in magnetic performance. The system includes auto explosion-proof ignition and emergency N2 purging for absolute safety.



Key Advantages



  • Safety Hydrogen Control: Features auto-ignition, N2 pre-purging, and real-time pressure monitoring with multi-level logic interlocks for secure H2 operation.

  • High Cleanliness: Utilizes high-quality stainless steel vacuum tanks with a strict leak rate (≤ 2 Pa/h), ensuring an environment free of dust, oil, and volatile contaminants.

  • Magnetic Optimization: Precise cooling rate control satisfies the specific physical property curves of Permalloy, significantly enhancing magnetic permeability.

  • Precision Heating: Equipped with Swedish Kanthal or high-performance alloy elements, ensuring superior thermal uniformity for consistent mass production.
