Nickel sulfamate,also known as nickel sulfonate, is an inorganic compound with the chemical formula Ni(SO3NH2)2, which is mainly used for precision nickel plating. It has the advantages of low internal stress in the coating and fast deposition speed. 

The melting point of nickel sulfamate is 205 °C, soluble in water and liquid ammonia, slightly soluble in acetone, and its aqueous solution is acidic and hygroscopic. It deliquescent quickly in moist air and slowly weathering in dry air. When heated, it loses four molecules of water, and when the temperature is above 110 degrees Celsius, it begins to decompose and form basic salts, and when it is heated further, it forms a mixture of brownish-black nickel trioxide and green nickel oxide.

Nickel sulfamate is an excellent electroplating main salt, which has been widely used in electronics, automobiles, aerospace, weapons, coinage, metallurgy, nickel mesh, radio, color aluminum alloy and other industries because of its low internal stress, fast electroplating speed, high solubility and no pollution.
