Aluminum-beryllium master alloy is an additive required for the smelting of magnesium alloy and aluminum alloy. During the melting and refining process of aluminum-magnesium alloy, magnesium element oxidizes before aluminum due to its activity to form a large amount of loose magnesium oxide film, resulting in a large amount of inclusions in the aluminum alloy, which seriously affects the ingot quality and mechanical properties of aluminum-magnesium alloy.
Beryllium metal has a small atomic radius and is more active than magnesium. It oxidizes before magnesium ingot to form a dense oxide film to protect the alloy melt. In particular, beryllium with a small atomic size can fill the interatomic gaps of the loose magnesium oxide film, making the film dense and preventing the continued oxidation of magnesium, thereby obtaining high-quality aluminum-magnesium alloy.
Magnesium alloys usually require 8-20ppm, and aluminum alloys require 8-15ppm. Its functions are:
1. Improve the cleanliness, fluidity and corrosion resistance of magnesium and aluminum;
2. Protect the oxidation and combustion of magnesium and aluminum, and reduce the oxidation loss of elements;
3. Improve the organizational structure of the alloy, refine the grains, and increase the strength.
According to the needs of different alloy additions, the beryllium content of aluminum-beryllium intermediate alloys generally includes three types:AlBe1, AlBe3, and AlBe5.
