BS NS101 Nickel Silver: Premium Corrosion‑Resistant Alloy for Electronics & Architecture
NS101 (CuNi10Zn42Pb2) is the general purpose grade of nickel silver most commonly used for hot stamping to complex shapes and as machining rod for a wide variety of electrical and electronic components. It has good corrosion and tarnish resistance and is frequently specified for many architectural applications where best use is made of its pleasing silvery gold colour and resistance to atmospheric corrosion.
