Mac Nicro E207
AWS E Ni Cu 7
Descriptions & Applications:
Manufactured using a high purity nickel based copper alloyed core wire with a chemically basic flux coating, containing extra deoxidants to eliminate from the weld metal gases such as nitrogen. Designed to be used with conventional welding techniques, the strong arc encourages full penetration while the basic slag and deoxidisation system ensures the metallurgical integrity of the deposited weld metal. For welding wrought and cast alloys of similar composition such as:- BS NA13 & NA1. ASTM/UNS N°4400, N°4405 & M35-1 DIN 2.4360, 2.4361, 2.4365. Proprietary alloys include:- Inco, Monel 400, Monel R405, VDM NICORROS & NICORROS 5. Used to special advantage on site fabrication work when joint geometry and/or weather conditions make the use of inert gas welding processes impractical.
