Import 1j85 1j50 1j79 Soft Magnetic Alloy — Buy in wholesale FOB from Supplier in China

Sichuan Liaofu Special Steel Trading Co., Ltd., based in Chengdu, supplies 1J85, 1J50, and 1J79 soft magnetic alloys, which are nickel-iron based materials engineered for applications demanding high magnetic permeability and low coercivity. These alloys are available in multiple product forms including sheets, rods, and custom shapes to suit different manufacturing processes. The 1J85 grade, with approximately 80% nickel content, offers particularly high initial permeability, while 1J50 (approximately 50% nickel) and 1J79 (approximately 79% nickel) serve different balance points between permeability, saturation flux density, and cost.

Soft magnetic alloys in the 1J series are Chinese designations for materials broadly comparable to international grades such as Permalloy (1J79/1J85 equivalents) and HyMu 80. Typical specifications for 1J85 include a maximum permeability exceeding 100,000 and a saturation flux density around 0.75T, while 1J50 offers higher saturation at approximately 1.5T with lower permeability. These materials undergo precise heat treatment, typically in hydrogen atmosphere furnaces, to develop their optimal magnetic properties. The chemical composition, particularly carbon, sulfur, and phosphorus content, is tightly controlled; 1J85 is known for its very low carbon content, which is critical for achieving peak magnetic performance.

These alloys are used in transformer cores, current transformers, magnetic shielding, inductors, and precision instruments across the electronics, automotive, aerospace, and energy sectors. Manufacturers of sensitive electromagnetic components source these materials for their predictable and stable magnetic response. Sichuan Liaofu Special Steel Trading offers flexible order quantities and ships under FOB and CIF terms, with payment options including L/C and T/T. Buyers should confirm specific alloy certifications, available dimensions, and heat treatment status directly with the supplier.

Sichuan Liaofu Special Steel Trading Co., Ltd. is headquartered in Chengdu, Sichuan Province, China (postal code 610045). The company operates as a special steel trading entity, suggesting it sources from and distributes materials produced by established mills rather than manufacturing in-house. The supplier is listed at the harbor trust tier on the marketplace.

The listing does not provide details on the company's founding year, number of employees, annual turnover, or specific mill partnerships. Response rate data is currently unavailable, so initial enquiries may require patience. Buyers should request the company's business licence, references from existing customers, and details on their quality management system before entering into supply agreements. Direct communication will clarify whether Liaofu holds agency agreements with specific mills and what traceability documentation they can provide for each alloy batch.
