    Turbine blades are pure aluminum, which melts at 1220 degrees. They operate inside the compression chamber of the turbine to move gases that are around 1500 degrees. There’s a whole art to making them single crystals and optimizing flow rates so they don’t melt, or explode, or melt and explode. And a lot of work goes into making sure when they do melt and explode, they don’t turn into supersonic bullets. Just barely though, because armor is heavy.
