DETAILS
Features/Characteristics
SM ER4047 is commonly used not only in MIG or TIG application, but also as a general purpose brazing alloys providing a free-flowing filler metal and good corrosion resistance. ER4047 is recommended for welding or brazing aluminium alloys 3003, 6005, 6053, 6061, 6951, 7005 and cast alloys 710.0 and 711.0. ER4047 has an approximate melting range of 1070 – 1080 and the post anodizing colour tint is greyish-black. ER4047 High Silicon content, good fluidity, and reducing the hot cracking tendency to the minimum, increasing the shear strength of the weld.
