Looking for an alloy that stays stable under pressure, resists corrosion, and performs flawlessly in precision electronics? Meet Vernicon.
In the field of electrical engineering and precision instruments, materials must do more than withstand stress. They must deliver accuracy, reliability, and durability—even under extreme conditions. That’s why professionals turn to DOMADIA™ Vernicon (CuNi44Mn1).
Also known as DIN 2.0842 and standardized under DIN 17664, DOMADIA™ Vernicon is a copper-nickel-manganese alloy designed for top performance in electrical and thermal applications.
Let’s break down what makes it such a valuable material in industries ranging from electronics to aerospace.
What is DOMADIA™ Vernicon (CuNi44Mn1)?
DOMADIA™ Vernicon (CuNi44Mn1) is a Copper-Nickel-Manganese (CuNiMn) alloy specially formulated for high-performance electrical and thermal applications. It combines the unique benefits of its three core elements:
- Copper – Excellent conductivity and corrosion resistance
- Nickel – Adds strength, thermal stability, and oxidation resistance
- Manganese – Improves hardness, ductility, and resistance to deformation
Due to its approximate 44% nickel and 1% manganese content, DOMADIA™ Vernicon CuNi44Mn1 is:
- Non-magnetic
- Highly stable under temperature changes
- Ideal for applications requiring long-term precision
