ASTM B559-12

Standard Specification for Nickel-Coated, Copper-Clad Steel Wire for Electronic Application

ABSTRACT
This specification covers nickel-coated, round, copper-clad steel wire for electronic applications. The nickel-coated wire shall consist of the basis wire coated with nickel. Tensile strength and elongation of the nickel-coated wire shall conform to the specified requirements for the applicable size and class of copper-clad steel wire. The electrical resistivity shall not exceed the values specified. Continuity, adherence, and mass of the coating shall be determined. Necessary joints in the wire and rod prior to final coating and drawing shall be made.
SCOPE
1.1 This specification covers nickel-coated, round, copper-clad steel wire for electronic application.  
1.2 Nickel coatings in mass percentages of the total mass of the coated wire are as follows: 2, 4, 7, 10, and 27 %. Nickel-coated wire having different minimum mass percentages of nickel may be obtained by mutual agreement between the manufacturer and the purchaser. For information purposes, the thickness of coating in microinches provided by the percentages listed above is shown in Table 1.TABLE 1 Nickel Mass Percent and Thickness of Coating
