When it comes to specialty alloys for demanding applications in aerospace, medical devices, and high-performance industrial components, Nilo46 stands out as a critical material choice. As a professional enterprise dedicated to high-purity metals and specialty alloys, Qingchuan New Materials (Zhengzhou) Co., Ltd. has established itself as a premier Nilo46 alloy manufacturer in China, serving global clients with precision-engineered solutions tailored to their specific requirements.
Understanding Nilo46 Alloy: Composition and Properties
Nilo46, also known as Kovar alloy, is a nickel-cobalt ferrous alloy specifically designed for applications requiring controlled thermal expansion properties. The “46” in its name refers to its approximate coefficient of thermal expansion (CTE) of 46×10⁻⁷/°C between 20-300°C, making it ideal for matching the thermal expansion characteristics of borosilicate glasses and certain ceramics.
The precise composition of Nilo46 typically includes:
- 29% Nickel (Ni)
- 17% Cobalt (Co)
- 0.2% Manganese (Mn)
- 0.02% Carbon (C)
- Balance Iron (Fe)
This specific formulation gives Nilo46 its unique combination of properties:
- Excellent thermal expansion matching with glass
- Good mechanical strength at elevated temperatures
- Excellent formability and weldability
- Stable performance in vacuum environments
- Resistance to oxidation at moderate temperatures

FAQ
What makes Nilo46 alloy suitable for hermetic sealing applications?
Nilo46’s key advantage for hermetic sealing is its coefficient of thermal expansion (CTE), which closely matches that of borosilicate glasses and certain ceramics. This means that when the sealed assembly experiences temperature changes, both the metal and glass components expand and contract at nearly identical rates, maintaining the seal integrity. Additionally, Nilo46 maintains good mechanical properties and formability, allowing it to be processed into various seal configurations.
How does Qingchuan ensure the quality of its Nilo46 alloy products?
At Qingchuan New Materials, we implement a multi-layered quality control system that includes: 1) Strict raw material inspection, 2) Precise process control during melting and forming, 3) Comprehensive testing of mechanical properties and thermal expansion coefficients, and 4) Final inspection of all finished products. Our facility is equipped with advanced analytical equipment including spectral analyzers and thermal expansion measurement systems to verify every batch meets specifications.
Can you provide Nilo46 alloy in forms other than standard sheet or rod?
Absolutely. As a custom Nilo46 alloy manufacturer, we can produce the material in various forms to meet specific application requirements. This includes wire for spring applications, tubes for specialized feedthroughs, and custom-shaped components through our precision machining services. We work closely with clients to determine the optimal form and dimensions for their particular use case.
What is the typical lead time for custom Nilo46 alloy orders?
Lead times depend on several factors including order quantity, required form (raw material vs. finished component), and current production schedules. For standard Nilo46 sheet or rod in common sizes, we can often ship within 2-3 weeks. For custom orders requiring special processing or machining, lead times typically range from 4-8 weeks. We always strive to accommodate urgent requests when possible and provide realistic timelines during the quotation process.
Does Nilo46 alloy require special handling or storage conditions?
While Nilo46 is more robust than some specialty alloys, proper handling and storage help maintain its properties. We recommend storing the material in a clean, dry environment away from extreme temperatures. During machining, standard coolants and lubricants suitable for nickel-based alloys can be used. For hermetic sealing applications, careful cleaning procedures are essential to remove any contaminants that might affect seal quality.
