Tariff Escalation: A New Challenge for Global Markets   In 2025, the U.S.-China trade war entered a new phase of escalation, with the U.S. government imposing unprecedented tariff increases. At the beginning of the year, U.S. President Donald Trump announced a 10% tariff on Chinese imports, which was further increased to 20% on March 4. On April 2, the Trump administration escalated pressure again, imposing an additional 34% tariff, bringing the total tariff rate to 54%, while also canceling the duty-free policy for small Chinese packages. Trump warned that if China did not remove its tariffs on U.S. imports, an additional 50% tariff would be imposed starting April 10, bringing the total rate to 145%.  In response, China swiftly implemented countermeasures, imposing a reciprocal tariff on U.S. goods on April 11.   Furthermore, the Trump administration expanded its tariff policies, imposing a universal 10% tariff on all global imports and additional duties on 60 other countries. These measures intensified global trade uncertainties, severely impacting multiple industries.   However, amid this market turbulence, heating alloy products have demonstrated unexpected resilience, standing out as one of the few industries largely unaffected by these new tariffs.   Heating Alloy Materials: Stable Demand in High-Latitude Markets   As a leading manufacturer of heating alloy materials, Jiangyin Chengxin Alloy Material Co., Ltd. has maintained steady growth despite the ongoing trade war.

1. Overview of Alloy Types and Magnetic Characteristics Chengxin alloy wires encompass various industrial-grade alloys primarily based on nickel, chromium, and copper.  The main alloy types include:   Pure Nickel (Nickel 200 / 201): A paramagnetic material with excellent corrosion resistance and high electrical conductivity. Magnetically, pure nickel is generally paramagnetic at room temperature but may exhibit weak ferromagnetism at low temperatures or along specific crystallographic directions. Its magnetic permeability is close to that of air, resulting in minimal magnetic field distortion.   Nickel-Chromium Alloys (NiCr series): Such as Cr20Ni35 and Ni80Cr20, these are widely used for heating elements and high-resistance components due to their superior oxidation resistance at high temperatures. The high chromium content reduces the overall magnetic response, ensuring paramagnetic behavior with minimal magnetic hysteresis or eddy current losses under alternating magnetic fields.   Copper-Nickel Alloys (CuNi): Including Constantan (CuNi19) and CuNi8, these alloys are known for their high stability and extremely low magnetic susceptibility, making them ideal for use in electronic metering and precision sensors. Their resistance to magnetic interference ensures signal stability.    NiFe Alloys (used in PTC materials): The addition of iron improves the temperature coefficient of resistance, a key factor in achieving PTC (Positive Temperature Coefficient) effects. While some iron-based alloys can be weakly ferromagnetic, controlled alloying and grain refinement in Chengxin’s formulations retain low magnetic responsiveness.   In summary, Chengxin alloy wires are predominantly paramagnetic, exhibiting low magnetic responsiveness, negligible hysteresis, and virtually zero remanence—ideal for applications requiring electromagnetic compatibility (EMC). 2. Typical Application Scenarios Based on their magnetic properties, Chengxin alloy wires offer excellent reliability and versatility in the following fields: ✅ High-Frequency Resistive Components (Induction Heating, Infrared Heating Elements, PTC Thermistors) In induction heating systems, metal components are exposed to strong alternating magnetic fields. Magnetic materials can suffer energy losses due to hysteresis and eddy current heating. NiCr and CuNi alloys from Chengxin, with their low permeability and thermal stability, significantly reduce such losses. PTC NiFe wires are also used in thermal regulation systems, where their paramagnetism minimizes magnetic-thermal interaction and enhances uniformity and responsiveness. ✅ Precision Sensing Systems (Thermocouples, Strain Gauges, Precision Bridges) Constantan wires are widely used in thermocouples, strain gauges, and high-precision bridge circuits due to their near-zero thermoelectric power and low magnetic susceptibility. Their immunity to magnetic noise ensures accurate data acquisition even in electromagnetically noisy environments. ✅ Medical Equipment and Industrial Automation In medical imaging equipment such as MRI and CT scanners, where magnetic compatibility is critical, Chengxin’s pure nickel and nickel-chromium wires offer minimal magnetic distortion. Similarly, in industrial automation systems, materials with low magnetic interference help maintain precision in actuator responses. 3. Magnetic Property Optimization and Material Engineering To meet the demands of emerging magnetic devices and highly sensitive sensors, the magnetic properties of Chengxin alloy wires can be enhanced through the following strategies: 1. Minor Alloying Element Doping Introducing trace elements such as Fe, Co, or Mn into CuNi or NiCr alloys can modulate magnetic behavior: Fe doping increases magnetic permeability; Co enhances high-frequency responsiveness; Mn suppresses remanence. These adjustments enable targeted magnetic behavior for sensors and actuators. 2. Surface Coatings and Nano-Modification Applying magnetically neutral coatings—such as chromium oxide or titanium nitride—via chemical or physical vapor deposition (CVD/PVD) can reduce magnetic leakage and coupling effects, enhancing reliability under electromagnetic interference (EMI). 3. Multi-Core Structures and Composite Material Design Developing multi-core or metal–ceramic composite wires allows fine-tuning of thermal, electrical, and magnetic pathways. Such designs are especially suited for multifunctional applications such as magneto-thermal regulation or smart sensing wires. 4. Recommended Experimental Verification For in-depth analysis and validation of Chengxin alloy wires’ magnetic properties, the following experimental tests are recommended:   Magnetic Susceptibility TestingUse Vibrating Sample Magnetometers (VSM) or Superconducting Quantum Interference Devices (SQUID) to obtain M–H curves and identify saturation and linear magnetic response regions. Frequency Response and Magnetic Loss AssessmentEvaluate magnetic loss and phase shift under alternating magnetic fields from 1 kHz to 10 MHz to support high-frequency applications such as induction heating. Environmental Adaptability TestingAssess magnetic stability under extreme conditions (e.g., >200°C, >95% RH, or below −40°C) to ensure reliability in medical and industrial sensor systems.   ✅ Conclusion Chengxin alloy wires exhibit advantageous paramagnetic properties, thermal stability, and electrical performance. These characteristics make them well-suited for high-frequency, precision, and low magnetic interference environments. With ongoing development in microalloying, structural design, and surface engineering, their magnetic performance can be further tailored for next-generation applications in smart sensing, magnetic actuation, and magneto-thermal energy systems.
