ER55-B2-Mn H08Mn2SiMOA H08MnSiCuCrNi
Performance
This product adapts advanced copper electroplating
technology. The surface of welding wire is smooth and
level and the copper layer is uniform and firm. Being
adapted cisarrangement technique, it has excellent weld
technology property. Particularly it is suitable
construct weld used at negative temperature. The welding
line has good impacting rough. It has many advantages
such as high productive efficiency, low cost, atmosphere
corrosion and good function, etc. |
