Product Description
Customizable CuNi44 Copper-Nickel Rod
High-performance binary alloy rod with exceptional thermal stability, corrosion resistance, and mechanical workability for demanding industrial applications.
Product Overview
CuNi44 copper-nickel rod from Huona New Material is a premium binary alloy composed of 44% nickel and 56% copper with trace stabilizing elements. Manufactured through advanced processes including vacuum smelting, hot forging, precision turning, and solution annealing, this rod delivers superior corrosion resistance, stable electrical properties, and excellent mechanical workability. Available in customizable diameters (5-200mm) and lengths (1000-6000mm), it serves critical roles in marine engineering, chemical equipment, and precision instrumentation.
Material Specifications & Standards
- Alloy Grade: CuNi44 (equivalent to UNS C71500, DIN 2.0882, GB/T 2040-2017)
- Chemical Composition: Ni 43.0-45.0%, Cu balance, Fe ≤0.5%, Mn ≤0.5%, C ≤0.1%
