What are 1J50 and 1J79 soft magnetic alloys used for?
Answer
Magnetic housing / core parts Silicon steel (Fe-Si) Laminations; AC-oriented parts Permalloy (Fe-Ni) High-permeability / shielding parts Fe-Al / Fe-Si-Al alloys Wear-resistant magnetic parts Fe-Co alloys High-saturation demanding parts Soft ferrites High-frequency / non-formed parts Nanocrystalline / amorphous Tape cores; specialized elements Strong / high Medium / good Application dependent Not typical / specialized Qualitative engineering comparison — validate against grade-specific data for each program. Validate each candidate grade against measured data for the actual forming route and heat treatment.
Why this page is short
Published material currently supports only part of this question. The page states what is known and stops, rather than filling the gap with a plausible number. The missing detail sits on the review board waiting for an engineer.

- Electrical Pure Iron for Solenoid Valve Housings | BalfordPure Iron and Manufacturing Processes Pure iron can be deep drawn, cold extruded and machined, and the same caution applies as for other soft magnetic metals: cold deformation introduces internal stress, and the finished component — not the raw material — defines the magnetic result.

What an engineer still needs from you
- material and material condition (grade, temper)
- material thickness, plus the key diameter, height and wall thickness
- tolerances, burr direction and the visual acceptance standard
- annual volume - it decides whether tooling is single-hit, progressive or transfer
- surface finish, and any secondary machining, annealing or plating
Need a DFM feasibility assessment for your project?
Send the engineering drawing (STEP or PDF) with the material grade, thickness and annual volume. Balford engineers then check it against the process window - draw ratio, wall thickness, tolerances, blank and tooling route - and come back with what is feasible and what is not. An answer on this page cannot replace that review.
