- Q: Is steel easier to weld?Which is more brittle/less flexible?
- Note: the easiest way to join steel to aluminum is to drill holes and BOLT them together...... You cannot WELD steel to aluminum.(except using extreme methods like explosion welding......) For all intents and purposes they are dissimilar metals, meaning they will not bond to each other. Also, aluminum has a much lower melting point than steel. It is possible to join steel and aluminum by *Soldering,* using tin/zinc hard solder. This requires a special flux designed exclusively for soldering aluminum though. The heating process is also a bit delicate as you must avoid overheating the joint. I work as a welder and I've only soldered Al three or four times. Steel is easiest to weld by far. If you set the equipment correctly, a six year-old kid can make a good weld on steel. Aluminum requires special equipment and procedures to weld. It's not easy. The brittleness of aluminum depends on it's alloy content. Most of the aluminum that's used today is not pure, rather it's in the form of aluminum ALLOYS which contain either zinc, magnesium, silicon, or manganese. these elements increase the strength dramatically, but also make it much less ductile. Commercially pure (CP) aluminum is very ductile, but it's also rather weak. Pure aluminum is used to make aluminum foil, as it's so soft and ductile it can easily be rolled paper-thin. The best aluminum alloys can come near in strength to mild steel, but weigh less than half as much as steel. Note that steel itself is an alloy of iron and carbon, Carbon increases the strength of iron in the same way that zinc or magnesium increase aluminum's strength. Most of the commonly used aluminum alloys are somewhat more brittle than mild steel, but not greatly so.
