NT-Cu

Specification
AWS Specification: AWS A5.7 ER Cu
JIS Specification: N/A
Other Specification: N/A
Description
  • NT-Cu is a deoxidized copper alloy developed to provide dense, high quality deposits with relatively high electrical conductivity for use in joining and overlay with the inert-gas processes
  • Primarily used to fabricate deoxidized copper and repair weld copper castings with the gas metal-arc and gas tungsten-arc processes
  • May also be used to weld galvanized steel and deoxidized copper to mild steel where high strength joints are not required
  • Used to overlay surfaces to resist corrosion
  • Features trouble-free wire feeding efficiency and highest quality weld deposits

Typical data and test results for mechanical properties, deposit, or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design, and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
