Core Product Portfolio: Specialty Alloys for Demanding Applications
Qingchuan New Materials maintains an extensive product range designed to meet the most stringent requirements of modern engineering applications. Their flagship offerings include:
1. NiCr8020 Alloy Series (Ni80Cr20, Cr20Ni80, Nichrome80)
This nickel-chromium alloy family represents the cornerstone of the company’s high-temperature resistant materials. With precise composition control (typically 80% nickel and 20% chromium), these alloys demonstrate exceptional oxidation resistance up to 1200°C (2192°F), making them ideal for heating elements, industrial furnaces, and thermal processing equipment. The consistent microstructure achieved through advanced melting and processing techniques ensures uniform electrical resistance and long-term stability in continuous operation conditions.
2. High-Purity Material Solutions
The company’s high-purity materials division specializes in producing chromium flakes, chromium powder, and evaporation materials with purity levels exceeding 99.9%. These products serve critical applications in vacuum coating, semiconductor manufacturing, and magnetron sputtering targets. The advanced degassing processes employed eliminate impurities that could compromise thin-film quality in precision optical coatings or semiconductor device fabrication.
3. Superalloy Castings and Wrought Products
Qingchuan’s superalloy capabilities span both cast and wrought forms, including nickel-based, cobalt-based, and iron-based variants. Their investment casting process produces complex turbine blades and vanes with minimal post-processing requirements, while the forging and rolling operations yield wrought products with superior mechanical properties for demanding structural applications. The company’s powder metallurgy expertise further enables the production of near-net-shape components with optimized material utilization.

FAQ
What distinguishes NiCr8020 alloy from other nickel-chromium compositions?
NiCr8020 (80% Ni, 20% Cr) offers optimal balance between electrical resistance and oxidation resistance at high temperatures. Compared to Ni60Cr40, it provides better oxidation resistance above 1100°C, while maintaining stable electrical properties for heating applications. The precise composition control in Qingchuan’s production ensures consistent performance across batches.
How does your company ensure the purity of chromium evaporation materials?
Our production employs multiple purification stages including vacuum distillation and electron beam melting. Each batch undergoes ICP-MS analysis to verify purity levels exceeding 99.99%. The entire process occurs in controlled environments to prevent contamination, with documentation traceable to raw material sources.
What certification standards do your medical alloy products meet?
Our medical-grade materials comply with ASTM F136 for implantable devices and ISO 5832-3 for surgical implants. The manufacturing facilities maintain ISO 13485 certification, with additional validation processes for specific customer requirements including USP Class VI biocompatibility testing when needed.
Can you provide custom alloy compositions for specialized applications?
Yes, our R&D team works closely with customers to develop tailored alloy formulations. We have successfully developed proprietary compositions for aerospace clients requiring specific strength-to-weight ratios or corrosion resistance profiles. Minimum order quantities apply for custom developments.
What lead times should be expected for superalloy castings?
Standard investment castings typically require 4-6 weeks from order confirmation to delivery, depending on complexity. For urgent requirements, we offer expedited services with 2-3 week lead times at additional cost. Wrought products generally have shorter lead times of 2-4 weeks.
