Declafor 1015 | CuNi7.5Sn5Te | C72670 key properties 

Declafor 1015 | CuNi7.5Sn5Te | C72670 is a copper‑nickel‑tin alloy engineered for applications requiring very high mechanical properties, excellent fatigue resistance and low friction behavior. Enhanced by tellurium addition, the alloy offers improved machinability and polishing performance, making it suitable for precision components and high‑performance electronic applications. 

Declafor 1015 | CuNi7.5Sn5Te | C72670 exhibits high elasticity, good stress relaxation resistance and excellent formability, enabling the production of complex components with consistent mechanical performance. As a spinodal copper‑nickel‑tin alloy, its specific microstructure provides outstanding mechanical properties after heat treatment, while maintaining good corrosion resistance, fair electrical conductivity and effective electromagnetic shielding performance. Strictly non‑magnetic by nature, it is well suited for demanding environments requiring reliability and durability. 

As a copper‑nickel‑tin alloy, Declafor 1015 delivers a balanced combination of strength, fatigue resistance, machinability and dimensional stability, making it a dependable solution for high‑precision and high‑performance components.
