NbHf C103 Niobium Hafnium Alloy Wire
NbHf C103 wire is a niobium-based alloy containing approximately 10% hafnium and 1% titanium, developed for components that operate under high temperatures and demanding service conditions. Compared with commercially pure niobium, C103 offers improved high-temperature strength, better creep resistance, and greater structural stability while maintaining good formability and weldability.
These characteristics make it a practical choice for aerospace hardware, vacuum systems, research equipment, and other applications where reliable performance is required during prolonged exposure to elevated temperatures.
At Shaanxi Zhongheng Weichuang Metal Materials Co., Ltd., C103 alloy wire is produced from carefully selected raw materials using vacuum melting and precision wire drawing processes to ensure consistent composition, stable dimensions, and dependable quality.

Manufacturing Capabilities
Key Features
C103 alloy wire combines the low density of niobium with the strengthening effect of hafnium and titanium, making it suitable for applications where both weight and high-temperature performance are important. The alloy retains good mechanical strength at elevated temperatures, offers improved resistance to creep deformation compared with pure niobium, and can be fabricated using conventional forming and welding methods designed for refractory metals. Its compatibility with vacuum environments and thermal cycling also makes it a preferred material for many aerospace and scientific applications requiring long-term dimensional stability.
Typical Applications
NbHf C103 wire is used in industries where materials must perform reliably under high temperatures, thermal cycling, or vacuum conditions. Typical applications include rocket propulsion components, aerospace thermal protection systems, vacuum furnace heating elements, high-temperature fasteners, scientific research equipment, and custom assemblies for advanced engineering projects. Depending on the specific application, the wire may be supplied for direct use or further processed into welded, formed, or machined components.
Manufacturing & Customization
Our manufacturing process begins with vacuum-melted C103 alloy ingots, followed by forging, hot working, precision wire drawing, annealing, and final inspection. Each stage is carefully controlled to achieve stable dimensions and consistent material properties. In addition to standard wire sizes, we provide custom diameters, coil lengths, straightened wire, cut-to-length products, and drawing-based manufacturing to meet the requirements of research institutions, equipment manufacturers, and industrial customers. Technical support is available during material selection and production to help ensure the finished product matches the intended application.
Quality Control
Quality control is carried out throughout the manufacturing process rather than only at the final inspection stage. Chemical composition, dimensional accuracy, surface condition, and other specified inspection items are verified according to customer requirements. Material certificates, chemical analysis reports, and third-party inspection can also be provided when requested, allowing customers to maintain complete traceability from raw material to finished product.
Packing & Delivery
C103 alloy wire is packaged according to international export standards to minimize the risk of contamination and mechanical damage during transportation. Depending on the product size and shipping method, wire can be supplied on plastic spools, in moisture-resistant packaging, vacuum-sealed bags, or reinforced wooden cases. Customized packaging and labeling are also available to meet project or distribution requirements.
FAQ
Q: Can you manufacture non-standard wire diameters?
A: Yes. Custom diameters, tolerances, and coil lengths can be produced according to customer drawings or technical specifications.
What supply condition is available?
