1J33 Soft Magnetic Precision Alloy Tubes
ZYTC Alloy, a reliable Chinese precision alloy supplier, provides premium 1J33 soft magnetic precision alloy tubes for instrumentation and electromagnetic industries. Also known as Ni33Al or 33H alloy, this iron-nickel-aluminum temperature compensation soft magnetic alloy is manufactured following GB/T standards. Our 1J33 seamless and welded tubes are produced under strict quality inspection, supporting custom dimensions and global export services.
1J33 is a specialized temperature compensation soft magnetic alloy. With the addition of aluminum, the material achieves high electrical resistivity, low coercivity and stable permeability. Its magnetic induction changes in a predictable manner within the temperature range of -40¡ãC to +80¡ãC, which is used to offset temperature drift in permanent magnetic circuits and precision electromagnetic loops. The alloy is widely fabricated into precision tubes, suitable for magnetic shunt compensators, voltage regulators and a variety of precision electrical instruments.
