In order to solve the defects of low strontium content and high smelting temperature in the prior art, the adopted technical scheme is as follows:
An aluminum-strontium intermediate alloy, the mass content of strontium element is 72%-92%, and the mass content of aluminum element is 8%-28%.
In order to obtain a master alloy with high strontium content and high performance, the raw materials of the above-mentioned aluminum strontium master alloy include: 99.7% pure aluminum ingot, 99% metal strontium and aluminum strontium 10 alloy, wherein, the mass ratio of aluminum strontium 10 alloy and metal strontium is 1:(6-9).
