Aluminum's melting point, roughly 1,220°F for the pure metal compared with well over 2,500°F for most steels, has practical consequences for any shop that processes both materials. Shops that move between steel and aluminum work every week see these effects firsthand.
A recent Metal Supermarkets blog article covers several of them. Aluminum gives no visual color change before melting, so operators accustomed to steel lose a familiar cue. Its high thermal conductivity draws heat away from the joint, which often calls for higher initial heat input despite the lower melting point. The surface oxide layer melts at a much higher temperature than the base metal, making joint cleaning and correct process settings essential for sound welds. Alloy composition also shifts the melting range, which matters when selecting grades for heat-exposed applications.
For teams qualifying procedures, training new welders, or moving production between materials, these differences are worth building into work instructions rather than learning through scrap. Our Marietta location stocks aluminum sheet, plate, bar, tube, angle, and channel, processed to size with no minimum order. The full article is linked in the comments. Metal Supermarkets Atlanta (Northwest) has supported fabricators across Cobb County and the surrounding area since 2004.
How does your team prepare welders who are moving from steel to aluminum work?
