Permalloy Soft Magnetic Alloy Strip & Bar: Grades 1J22, 1J79, 1J50, 1J85 from Cheng Yuan Alloy

Permalloy Soft Magnetic Alloy Strip & Bar: Grades 1J22, 1J79, 1J50, 1J85 from Cheng Yuan Alloy

Permalloy is a nickel‑iron soft magnetic alloy widely used in transformer cores, magnetic shielding, and precision electromagnetic components. Shijiazhuang Cheng Yuan Alloy Material Co., Ltd supplies Permalloy in strip, bar, sheet, and wire forms across multiple standard grades, including 1J22, 1J79, 1J50, and 1J85.

What Is a Permalloy Soft Magnetic Alloy?

Permalloy is classified as a soft magnetic alloy made of nickel‑iron alloy. It exhibits high initial permeability (10,000–200,000), low coercivity (0.4–8.0 A/m), and saturation magnetic flux density ranging from 0.6 to 2.35 T. These properties make it ideal for applications that require efficient magnetic flux conduction with minimal energy loss, such as signal transformers, EMI shielding enclosures, and high‑frequency inductors.

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). The soft magnetic alloy segment alone 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 share, with China as the leading producer.

Key Challenges in Selecting Soft Magnetic Alloys

Engineers and procurement professionals face several challenges when choosing a soft magnetic alloy for transformers, shielding, or motor cores:

• Magnetic performance consistency – variations in permeability and core loss between batches cause signal distortion or overheating.
• Compliance with international standards – alloys must meet ASTM A753 (for high‑permeability materials) or GB/T 15014.
• Dimensional precision – strip thickness tolerance of ±0.002 mm is often required for stacked laminations.
• Reliable supply chain – long lead times disrupt project schedules; OEM/ODM capabilities matter.

Industry Background: Soft Magnetic Alloy Manufacturing

Major global manufacturers of high‑performance soft magnetic alloys include Vacuumschmelze (VAC), Proterial (formerly Hitachi Metals), Carpenter Technology, and Arnold Magnetic Technologies. China has become a significant production base, contributing to the Asia‑Pacific region’s 41.0%–49.37% share of the global market. Cheng Yuan Alloy is one such Chinese manufacturer, established in 2021, that focuses on the Permalloy family.

Cheng Yuan Alloy’s R&D team consists of 5 engineers, with a manufacturing facility covering 200 m² and an annual output of 10–15 million USD. The company’s export business accounts for 50% of sales, with major markets in Russia, Germany, France, Italy, the United States, Canada, South Korea, Japan, Brazil, and India.

How to Select and Order Permalloy: Step‑by‑Step

1. Identify the application – Determine whether you need high permeability (e.g., 1J79, 1J85 for shielding) or high saturation (e.g., 1J22 for motors and electromagnets).
2. Check standard compliance – Alloys such as 1J79, 1J50, and 1J85 comply with ASTM A753 and GB/T 15014. 1J22 (HiperCo50) meets ASTM A801 Type 1.
3. Specify dimensions – Provide thickness (0.01–2.0 mm), width (2–300 mm), and required surface roughness (Ra ≤ 0.8 μm).
4. Request a quotation – Contact Cheng Yuan Alloy via email (chengyuan.alexey@gmail.com) or WhatsApp (+86 13673186216).
5. Order sample testing – Small‑quantity samples are available to verify magnetic performance under your specific operating conditions.

Use Cases of Permalloy

• Aerospace – 1J22 used in generators, precision motors, electromagnet poles, and magnetron tubes operating from −60 °C to 120 °C under alternating magnetic fields.
• Transformer cores & magnetic shielding – 1J79, 1J85 provide ultra‑high permeability for weak‑signal processing.
• New energy vehicles – High‑frequency low‑loss cores for on‑board chargers, enabling 40% size reduction on 800 V platforms.
• Audio equipment – Permalloy audio transformers deliver low‑distortion signal transmission.
• Precision instrumentation – Magnetic amplifiers, current sensors, and gyroscopes benefit from stable permeability over a wide temperature range (−60 °C to 130 °C).
