Pure aluminum (Al99.5) is not very strong. However, it is used as the basis for alloys with a strength that matches up to steel. Welding aluminum is particularly difficult because the material is surrounded by an oxide layer. This only melts at around 2015 degrees Celsius, while aluminum itself melts at around 650 degrees depending on the alloy.
