1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 7 NC-400 A CHEMICALLY BASIC FLUX COATED MMA ELECTRODE FOR WELDING NICKEL BASED ALLOYS CONTAINING 25% - 35% COPPER DATA SHEET NO. 85 SPECIFICATION AWS A5.11 BS EN ISO 14172 JIS Z 3224 CLASSIFICATION ENiCu-7 E Ni 4060 DNiCu-7 PRODUCT DESCRIPTION The chemically basic flux is extruded onto a fully alloyed core wire with respect to nickel and copper. The flux also contains titanium to refine the weld metal and manganese to supress hot cracking. The slag has a low viscosity but a fairly narrow solidification range. WELDING FEATURES OF THE ELECTRODE The electrode is suitable for use on DC+ only. The slag fluidity and solidification range ensures excellent positional welding while the use of titanium ensures weld metal refinement and freedom from porosity. Metal recovery is some 100% with respect to the weight of the core wire. APPLICATIONS AND MATERIALS TO BE WELDED For welding nickel, copper alloys, cast or wrought, including on site pipework. Typical materials are : ASTM - ASME UNS N04400, N04405, N05500. A4.94 M35-1 cast A494 M35 cast. Proprietary alloys include: Monel 400 - R405 - K500 (special metals) It may also be used to weld Ni-Cu alloys to nickel, cupro-nickel and these to stainless steels.
