Qingchuan New Materials (Zhengzhou) Co., Ltd. stands as a leading manufacturer of specialty alloys and high-purity materials, serving global industries with cutting-edge metallurgical solutions. Our modern production facility in Zhengzhou High-Tech Industrial Development Zone combines advanced technology with rigorous quality control to deliver materials that meet the most demanding specifications across aerospace, medical, automotive, and semiconductor sectors.
Core Product Range: Inconel713C Specialty Alloys
Our flagship Inconel713C product line includes four critical forms tailored for precision manufacturing:
1. Inconel713C Round Bars
Manufactured through vacuum arc remelting (VAR) and hot rolling processes, our round bars achieve uniform microstructure and exceptional mechanical properties. With diameters ranging from 10mm to 300mm, these bars serve as primary material for turbine blades, medical implants, and tooling components. The controlled composition ensures optimal creep resistance at temperatures exceeding 1000°C.
2. Inconel713C Ingots
Our 500kg-2000kg ingots provide the foundation for custom forging operations. Produced in induction furnaces with inert gas protection, these ingots exhibit minimal segregation and excellent hot workability. The consistent chemical composition enables predictable behavior during subsequent processing stages.
3. Inconel713C Forging Blanks
Pre-formed to customer specifications, our forging blanks reduce material waste and processing time. The precision-cut dimensions accommodate various forging equipment while maintaining metallurgical integrity through specialized heat treatment protocols.
4. Inconel713C Master Alloys
Our master alloys enable precise composition control during alloy production. Formulated with 99.95% purity elements, these intermediates help manufacturers achieve consistent batch quality while optimizing production costs.

High-Purity Nickel Evaporation Materials
Complementing our alloy offerings, we produce high-purity nickel evaporation materials with purity levels exceeding 99.995%. These materials serve critical applications in:
- Optical coating systems
- Semiconductor device packaging
- Decorative thin film deposition
- Magnetic storage media production
Our evaporation materials undergo multiple purification stages including zone refining and electron beam melting to eliminate impurities that could affect film quality. The consistent evaporation rates ensure uniform coating thickness across large-area substrates.

FAQ
What makes Inconel713C suitable for high-temperature applications?
Inconel713C contains a precise balance of nickel, chromium, and aluminum that forms a protective oxide layer when exposed to heat. This gamma prime (γ’) phase provides exceptional creep resistance up to 1100°C, making it ideal for turbine blades and combustion chamber components.
How does your production process ensure material purity?
We implement triple purification: primary melting in inert atmosphere furnaces, secondary refining through vacuum arc remelting, and final purification via electron beam melting. Each batch undergoes GDMS analysis with detection limits below 0.1ppm for key impurities.
What certifications do your materials carry?
Our products comply with AMS 5837, ASTM B637, and EN 10204 3.1 standards. For medical applications, we provide materials meeting ASTM F136 and ISO 5832-3 requirements, with full biocompatibility testing reports available.
Can you supply custom alloy compositions?
Yes, our R&D team works with customers to develop tailored compositions. We maintain a library of over 200 master alloy formulas that can be adjusted within ±0.05% for key elements to meet specific application requirements.
