Modifying master alloys developed by STNM have well distributed chemical compositions and low content of impurities. With the features of good modifying ability, high efficiency and long lasting effect, they meet the use requirements of foundry aluminum alloys with various silicon content and modifying requirements.
① Uniform microstructure. Fine and uniform aluminum alloy structures form by strict control of alloying process and metallographic morphology. ② Precise and stable chemical compositions. The content of high-melting, active and segregational elements can get accurate control. ③ Low content of impurities. ④ Good performance, low melting point, and high recovery rate. It can realize low temperature addition and quick melting, and therefore shorten the processing time and improve production efficiency and product quality.
The chemical composition of magnesium master alloys are uniform and stable, meeting the requirements of composition and microstructure adjusting, as well as performance improvement of magnesium alloys.
