Aluminum filler metals meet AWS Specification A5.10

May 12, 2009

Hobart Brothers has added two new lines of aluminum solid welding wires and GTAW cut lengths to its McKay® brand of filler metals. The company joined in a strategic relationship with Maxal Aluminum to offer the new products.

Smootharc™ 5356 is a magnesium-based alloy that provides good strength for structural applications, especially those in the transportation field, and it resists hot cracking. The alloy also is suitable for components that need to be anodized. Smootharc 4043 also resists weld cracking, and its higher level of silicon provides good wetting action.

Both solid wires are available in 0.030-, 0.035-, and 3/64-in. diameters on 1-lb. spools or 12- and 16-lb. reels, all of which are shipped in a heavyweight, reusable plastic bag and a sturdy, double-wall package to protect the wire from contamination.

The GTAW cut lengths are available in 1/16-, 3/32-, and 1/8-in. diameters in industry-standard 36-in. lengths. The alloy number (4043 or 5356) is stamped on each end at every 12 in. The cut lengths ship in 10-lb. boxes with four to a master package, constructed of the same double-wall material as the spools and reels.

The products meet the requirements of AWS Specification A5.10, making them suitable for critical welding on heat exchangers, food manufacturing equipment, transportation equipment, and boating and shipyard applications.
