Standard Specification for Gold-Silver-Nickel Electrical Contact Alloy
STANDARD published on 1.11.2021
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers gold-silver-nickel alloy tubing, rod, wire, strip, and sheet material for sliding electrical contacts. Raw materials shall be of such quality and purity that the finished product will have the properties and characteristics prescribed in this specification. The material shall be finished by cold working, heat treating, annealing, turning, grinding, or pickling as are required to produce the prescribed properties. Material produced shall meet the chemical composition requirements. Mechanical properties such as tensile strength, elongation, Knoop hardness, microhardness, as well as the electrical contact shall conform to the prescribed specification.
