1, weldable nickel is a nickel alloy, containing elements other than nickel, such as cobalt, chromium, iron, etc., in order to provide specific physical and chemical properties; ordinary nickel refers to pure nickel or a small amount of nickel alloys, the composition of relatively pure.
2, welding nickel has high strength, good corrosion resistance and high temperature resistance, commonly used in welding high temperature corrosion-resistant environment components; ordinary nickel has a better electrical conductivity, ductility and corrosion resistance, commonly used in electronic components, chemical equipment and other fields.
3, welded nickel is mainly used in aerospace, petrochemical, nuclear engineering and other fields, for the manufacture of high-temperature environments and strong corrosive media under the components; ordinary nickel is widely used in the electronics industry, chemical industry, medical equipment and other fields.
