Nickel 201 wire JIS NW2200 / NW2201 is a critical material in modern furnace manufacturing and high-temperature engineering. At DLX, we supply high purity Nickel 201 wire to furnace manufacturers and engineering companies that require stability, consistency, and long service life in demanding thermal environments.
High-temperature systems are unforgiving. Materials must withstand continuous heat cycles, oxidation exposure, and mechanical stress without losing structural integrity. Nickel 201 wire is specifically engineered to meet these challenges through its ultra-low carbon composition and high nickel purity.
From our experience working with furnace manufacturers, reliability is the priority. A small material inconsistency can lead to equipment downtime or expensive maintenance. That is why DLX focuses on tight quality control and stable production standards.

The key advantage of Nickel 201 wire lies in its low carbon content. When pure nickel materials operate above 600°C, higher carbon levels can lead to graphite formation, reducing ductility and structural stability. Nickel 201 minimizes this risk, making it ideal for sustained high-temperature exposure.
Nickel 201 also demonstrates strong oxidation resistance. In furnace atmospheres, especially those containing controlled oxygen levels, the material forms a stable oxide layer that protects the underlying metal.
Mechanically, Nickel 201 maintains good ductility and formability even after prolonged thermal cycles. This allows furnace manufacturers to design heating elements, support wires, and internal components that retain their shape and performance over time.

Furnace manufacturers use Nickel 201 wire in resistance heating elements, internal structural supports, thermocouple protection components, and high-temperature electrical connectors.
In heat treatment furnaces, stable electrical resistance is essential. Nickel 201 wire provides predictable resistance values, which helps ensure uniform heat distribution inside the chamber.
In vacuum furnaces and controlled atmosphere systems, Nickel 201 performs reliably due to its chemical stability and low impurity content. This reduces contamination risk and supports precision thermal processes.
