Qingchuan New Materials (Zhengzhou) Co., Ltd. stands as a premier manufacturer specializing in the research, development, and production of high-purity metals, specialty alloys, and their related products. Strategically located in Zhengzhou High-Tech Industrial Development Zone, our modern facility houses state-of-the-art production lines and precision machining equipment specifically designed for specialty alloys and high-purity materials. This article provides an in-depth look at our core product lines, manufacturing capabilities, and application fields for our NiCr8020 alloy, UNSN06003, and other high-performance materials.
Core Product Lines: NiCr8020 Alloy & Specialty Alloys
Our product portfolio centers around three primary categories: nickel-based alloys, high-purity materials, and advanced manufacturing processes. The NiCr8020 alloy (also known as Nichrome80 or Cr20Ni80) represents our flagship product in the nickel-chromium family, containing approximately 80% nickel and 20% chromium by weight. This composition provides exceptional resistance to oxidation and corrosion at elevated temperatures, making it ideal for demanding industrial applications.
The UNSN06003 designation refers to a specific grade within the nickel-chromium-iron alloy family, characterized by its excellent mechanical properties and thermal stability. We produce this material in various forms including wrought superalloys, cast superalloys, and powder metallurgy products to meet different processing requirements. Our high-purity materials series includes degassed chromium flakes, chromium powder, and evaporation materials with purity levels exceeding 99.9%, essential for semiconductor and vacuum coating applications.

5. Industrial Tooling Import Substitution
The UNSN06003 alloy’s wear resistance and thermal stability make it an excellent alternative to imported materials for manufacturing taps, drills, and other cutting tools. We work with tooling manufacturers to develop customized alloy compositions that improve tool life and reduce production costs.
FAQ
What makes NiCr8020 alloy suitable for high-temperature applications?
The 80% nickel content in NiCr8020 provides excellent oxidation resistance at elevated temperatures, while the 20% chromium forms a protective chromium oxide layer on the surface. This combination allows the alloy to maintain its mechanical properties and resist corrosion even when exposed to temperatures exceeding 1000°C continuously.
How does your production process ensure material purity?
We implement multiple purification stages throughout production, starting with high-purity raw materials and using vacuum induction melting to minimize contamination. Our class 10,000 cleanroom facilities and specialized handling equipment prevent cross-contamination during processing. Each batch undergoes ICP-MS analysis to verify purity levels meet specifications before release.
What certifications do your medical-grade alloys comply with?
Our medical device materials comply with ASTM F136 for implantable applications and ISO 13485 for medical device quality management systems. We maintain complete material traceability from raw material suppliers to final product delivery, with batch-specific certificates of analysis available for every shipment.
Can you provide customized alloy compositions for specific applications?
Yes, our R&D team works closely with customers to develop tailored alloy formulations that meet specific performance requirements. We can adjust elemental compositions, processing parameters, and heat treatment protocols to optimize properties such as strength, ductility, corrosion resistance, or magnetic characteristics for your application.
