Kunial Copper-Nickel-Aluminum Alloy Products

Kunial grades and product forms

Kunial is a copper-nickel-aluminum alloy family described in legacy specifications as Kunial A or Kunial B. Those names do not alone define a modern U.S. substitute. Specify the governing standard, chemistry limits, condition and required mechanical properties; any proposed equivalent must be approved by the purchaser.

Sheet, strip, bar and wire enquiries

For sheet or strip, provide thickness, width, length or coil details, temper and surface finish. For bar or wire, state diameter, length or coil weight, tolerances and condition. If the material is intended for spring, marine or electrical service, identify the required corrosion, fatigue, conductivity or testing criteria rather than assuming that the grade name guarantees a particular result.
