OEM Permalloy Strip Manufacturer – Custom Soft Magnetic Alloys from Cheng Yuan Alloy

OEM Permalloy Strip Manufacturer – Custom Soft Magnetic Alloys from Cheng Yuan Alloy

When sourcing Permalloy strip or bar for EMI shielding, transformer cores, or high-speed motor laminations, engineers and procurement teams often need more than a standard off-the-shelf product: they need a manufacturer capable of customizing dimensions, magnetic properties, packaging, and labeling. Cheng Yuan Alloy (Shijiazhuang Cheng Yuan Alloy Material Co., Ltd.) is a specialized manufacturer of soft magnetic alloys, offering full OEM services for Permalloy strip and bar across grades 1J22, 1J79, 1J50, 1J85, 1J54, and others. This article explains how Cheng Yuan Alloy supports OEM projects, what capabilities it offers, and how to integrate its products into demanding applications.

Problem Definition: Why OEM Matters for Permalloy Strip Procurement

Standard Permalloy strip sizes or magnetic properties may not align with a specific transformer core design, EMI shielding housing, or sensor component. Projects often require:

• Custom thickness (0.01–2.0 mm) and width (2–300 mm)
• Tailored magnetic annealing to achieve target initial permeability (10,000–200,000) or maximum permeability (150,000–450,000)
• Specific packaging (coils, spools, cut lengths) and labeling for traceability
• OEM branding with logo and part numbers

Without a manufacturer that offers OEM services, procurement teams must compromise on design or source from multiple suppliers, increasing lead time and quality risk. Cheng Yuan Alloy addresses this gap with dedicated OEM production capabilities.

Industry Background: Soft Magnetic Alloys and the Permalloy Segment

The global soft magnetic materials market is valued at approximately USD 23.0 billion in 2025 and is projected to reach USD 33.9 billion by 2033 (Grand View Research). Within this, the soft magnetic alloy material segment is expected to grow at a CAGR of 3.1% from 2024 to 2030, reaching USD 4.14 billion (QY Research). Asia Pacific holds the largest market share, with China as the leading producer. Permalloy alloys such as 1J50, 1J79, and 1J85 are compliant with ASTM A753 and GB/T 15014 standards for high-permeability applications, while HiperCo 50 (1J22) is governed by ASTM A801 Type 1 for high-speed rotors. As demand for custom magnetic components increases—driven by new energy vehicles, aerospace, and precision instruments—the ability to source OEM Permalloy strip from a reliable manufacturer becomes a competitive advantage.

Detailed Solution: Cheng Yuan Alloy’s OEM Permalloy Strip Manufacturing

Cheng Yuan Alloy is a China-based manufacturer located in Shijiazhuang, Hebei Province, with access to convenient logistics. The company has accumulated rich experience in the production, inspection, packaging, and transportation of alloy materials. Its product portfolio includes Permalloy (nickel-iron soft magnetic alloys) in strip, sheet, bar, wire, and other forms, covering grades 1J22, HiperCo50, 1J79 (Ni79Mo4), 1J50 (FeNi50), 1J85, 1J54, 1J27, 1J34, 1J46, and others. The company offers full OEM services, including customization of size, logo, and package, as well as full OEM production services. With a monthly capacity of 300 tons and a lead time of 30 days, Cheng Yuan Alloy can handle both small R&D batches (MOQ 50 kg) and large mass orders (1–10 tons).

Step-by-Step Breakdown: How an OEM Permalloy Strip Project Works

1. Inquiry and Specification – The buyer provides target dimensions (thickness, width, length), required magnetic properties (permeability, saturation flux density, coercivity), and any additional requirements such as surface roughness (Ra ≤ 0.8 μm) or lamination factor (0.88–0.94).
2. Material Grade Recommendation – Based on the application (e.g., high-saturation cores for aerospace use 1J22; high-permeability shielding uses 1J79 or 1J85), the company advises on the most suitable grade and heat treatment.
3. Sample Production – For verification, a sample batch (from the 50 kg MOQ) is produced and tested. 100% quality control testing is performed for magnetic and dimensional parameters.
4. Customization – Size, logo (stamping, laser marking), packaging (coil, spool, cut-to-length), and export documentation are finalized according to buyer requirements.
5. Mass Production and Inspection – Full production run, with video, third-party, or picture inspection options. Payment terms: 30% deposit, 70% before shipment.
6. Delivery – Shipping via FOB, FCA, DAP, CIF, or CPT from Chinese ports. Main export markets include Russia, Germany, France, Italy, United States, Canada, South Korea, Japan, Brazil, and India.
7. After-Sales Support – Technical support (parameter and selection guidance), factory data testing, third-party testing, and transportation assistance.

Use Cases of Cheng Yuan Alloy OEM Permalloy Strip

Based on actual project experience, Cheng Yuan Alloy’s Permalloy products have been applied in:

• Aerospace components – High-saturation soft-magnetic cores for electromagnets and magnetostrictive transducer iron-cores, operating from -60°C to 120°C with long-term alternating magnetic field excitation. The ultra-high saturation flux density (up to 2.35 T for 1J22) enables downsizing of aerospace electromagnets.
• Precision instruments – Magnetic shielding parts made from 1J79 or 1J85 strip, providing high permeability (up to 200,000 initial permeability) to isolate complex electromagnetic interference.
• Audio equipment – Low-distortion cores for audio isolation transformers, utilizing 1J50 or 1J79 to realize low-distortion signal transmission.
• New energy vehicles – High-frequency cores for on-board chargers and drive motors, enabling a 40% volume reduction in 800V high-voltage platform components.
• Transformer cores and magnetic amplifiers – Custom-width strip for high-efficiency transformer laminations and magnetic modulators.

These projects typically involve conventional batch orders of 10–500 kg, with annual total sales exceeding USD 10 million. The products have demonstrated 8–15 years continuous stable service life under standard conditions, and up to 20 years for sealed aerospace equipment.
