Nickel Alloys: Standard Nickel Grades
JLC products are available in wire, rod, strip, and bar forms. The dimensional capabilities in these forms readily available are listed in the table below. Additional dimensions are available by request as per customer specifications.
Ni 200
Nickel 200 is the most widely used standard grades of commercially available pure wrought Nickel alongwith and Nickel 201. These alloys offer good thermal conductivity, mechanical properties, resistance against many corrosive environments, in particular against caustic alkalis, low electrical resistivity, and good magnetostrictive properties. Nickel 200 is easily workable by forming and drawing.
Ni 201
Nickel 201is a low carbon variation of Ni200 and has a very low work hardening rate which allows it to be easily cold formed. It also offers better creep resistance and is preferred over Ni200 for applications that experience temperatures over 600°F (315°C).
Ni 205
Nickel 205 is used for applications similar to those of Ni200, but mostly where higher purity and conductivity are required. Nickel 205 is produced by compositional adjustments to Ni200 chemistry. These adjustments help in improving properties needed for electrical and electronic applications.

Applications
Nickel 200 and 201 alloys are used as leads for electrical & electronic components & as lead-in-wire components for lamps. They are used in making wire mesh & filters for chemical & petrochemical industry. They are also used in Ni-Cd batteries, for welding overlay, and for making flux cored wires for welding applications.
