CW409J / NS106

Nickel Silver

CW409J / NS106

CW409J  is one of the most popular grades of nickel silver for deep drawing, spinning and other cold forming operations. It combines good strength and ductility with outstanding resistance to wear, corrosion and tarnish. It accepts a high degree of polish to a silvery white colour, aesthetically pleasing in its own right, while also providing an excellent base material for plated silverware – still one of its traditional uses. The alloy also finds many electrical and electronic applications and is readily soldered and silver brazed. The sheets are stocked in soft temper suitable for extensive cold working.
