Washington Alloy 4043
Washington Alloy 4043 (commonly referred to as AlSi5) is a 5% silicon aluminum filler metal that is available in spools or cut lengths for MIG or TIG processes. This alloy is recommended for welding 3003, 3004, 5052, 6061, 6063 and casting alloys 43, 355, 356 and 214. Washington Alloy 4043 has a melting range of 1065-1170oF and a density of .097 lb./cu. in. The post-anodizing color tint is gray. Tensile strength average is 29,000 psi.

Washington Alloy 4047
Washington Alloy 4047 (commonly referred to as “718 aluminum” or AlSi12) is an aluminum filler metal which contains approximately 12% silicon which is twice as much silicon contained in 4043. This alloy is commonly used not only in MIG or TIG applications, but also as a general purpose brazing alloy providing a free-flowing filler metal and good corrosion resistance. Washington Alloy 4047 is recommended for welding or brazing aluminum alloy: 1060, 1350, 3003, 3004, 3005, 5005, 5050, 6053, 6061, 6951, 7005, and cast alloys 710.0 and 711.0. Washington Alloy 4047 has an approximate melting range of 1070-1080oF and the post anodizing color tint is grayish-black.
