Description

 Character: silver color metal, good ductility, medium hardness and magnetic metal. Chemical properties are lively. Have good corrosion resistance, hard oxidation in the open air in room temperature, not easily to react with nitric, alkali corrosion. Flammable of Thin nickel wire, react with halogen as heating. Dissolved slowly in dilute acid, can absorb plenty of hydrogen
Boling point: ***2?
