They are used widely in all product forms for heat exchanger, other water treatment and cooling plant desalination etc.
BS 1400 G3	Unwrought	340min	170	18	-	Application for Nickel Gun Metal are many and varied, and include engine valve guides, resistance welding equipment Bearing bushes, Chuk Nuts, Gear Components, motion translation devices, New application for the alloys outstanding properties are being continuously developed.
BS 2870 NS 104	Half Hard Temper	4600 min	-	8 min	130	This is standard grade for general purpose applications where the addition a strength of half hard temper material imparts regidity and spring properties again the presence of Nickel provides corrosion and turnish resistance to levels well excess of normal Brasses material of this temper is still cold workable and fabricated by bending, punching, stamping etc.
