1J50 capillary tubes are precision-engineered from a nickel-iron soft magnetic alloy, specifically designed for applications requiring high magnetic permeability and low coercivity. With a composition of 49-51% nickel and balanced iron, this alloy delivers exceptional magnetic performance while maintaining excellent mechanical properties.
Key Performance Features:
-
High Permeability: Initial permeability (μi) ≥25,000, maximum permeability (μm) ≥100,000.
-
Low Coercivity: Hc ≤1.2 A/m for efficient energy conversion.
-
Thermal Stability: Maintains magnetic properties from -60°C to 120°C.
-
Fabrication Precision: Achieves inner diameters as small as 0.2mm with ±0.003mm tolerance.
Manufacturing Excellence
Our 1J50 capillary tubes are produced through:
-
Vacuum Induction Melting (VIM): Ensures ultra-low impurity levels.
-
Multi-Stage Cold Drawing: Achieves precise dimensional control.
-
Surface Enhancement: Electropolishing to Ra ≤0.1μm.
-
Quality Assurance: 100% eddy current testing.
