Heat treatability determines if a welded joint can be further strengthened by heat treatment after welding. Non-heat treatable rods (like 1100 and 5356) are ideal for applications where ease of use and corrosion resistance are more important than post-weld strength. Heat treatable rods (such as those for 6XXX series alloys) allow for enhanced mechanical properties after welding. Harris 5356 GTAW Aluminum Welding TIG Rod 3/32 36 is non-heat treatable but offers excellent all-purpose welds. With both types available, you can select a rod that matches your post-weld processing needs.
