Aluminum, once the most expensive metal in the world, is now commonplace. Finding aluminum was easy, but learning to refine it challenged some of the greatest minds of the 1800s. Just as it was tricky to refine, it is also tricky to weld, but once you learn, it becomes a regular part of welding life.

Aluminum has many properties that make it desirable in manufacturing. At approximately one-third the weight of steel, it is lightweight but has tensile strengths up to 90,000 lb/in.² (90 ksi). It is co..
