MG elements are widely added to aluminum alloys of different grades. The industrial production is usually added to aluminum melt in a pure MG ingot to the aluminum melt, but magnesium will prior to oxidation into a loose MGO film, which not only does not afford it. Instead, the alloy oxidation and Mg elements are burned, resulting in fluctuations from ingredient deviations and different batch product components, and also lead to oxidizing inclusion defects, giving magnesium-containing aluminum alloy production is greatly plagued. Based on this, Shandong University has developed an Al-50 mg intermediate alloy (AL-50 mg) for solving the above problems.

Table 9-1 is to formulate Al-XMG alloys from different furnaces using Al-50 mg, comparison with the formulation results of pure magnesium: 1) Mg absorption rate is higher; 2) Mg absorption rate is more stable; 3) low temperature and high temperature conditions The lower Mg content is basically consistent, and for pure magnesium, the burnt rate is significantly increased after the melting temperature is raised.
Product advantages
The melting point is low (about 450 ° C), which can be quickly dissolved.
The Mg content regulation is accurate, the absorption rate is high, and the MG content of different furnace products is small.
Add simple, energy saving, green, green, avoiding the flue gas and pollution problems caused by MG burning.
Time-saving provinces, the alloy is easy to break, easy to take, no need to cut the spare material.
Product specifications
The Al-50 mg intermediate alloy is mainly a spindle specification.
Application field
Suitable for mg aluminum alloys such as Al-Mg, Al-Mg-Si, etc.).
Suitable for adding Al elements to an AL magnesium alloy (such as AZ-based alloys, etc.).
