As I understand it, the Nazis already did have better alloys, but due to material shortages they couldn't produce those in sufficient amounts. The metallurgy problems that led to the comically short engine lives of the early German jets were problems of, "Make a good-enough alloy that can be mass produced with the resources at hand."
They didn't have enough fuel to fly the jets in sufficient quantities to make a major difference anyway.
