Applications

Copper-base 70/30 copper-nickel joining and surfacing; specify the exact base alloy and qualified procedure.

Selection guidance

Select the alloy family and documented size together. Cast-iron repair ENi-CI, pure-nickel ENi-1, copper-base ECuNi and nickel-base ENiCu-7 serve different material scopes. Enter the actual base-metal grade, any dissimilar material and your WPS separately.

Technical notes

Reference specifications and requested dimensions are retained separately. Where a source marks a size available on request, the note remains attached to that size. Packaging, batch documentation and delivery are confirmed in the quotation.
