In order to improve the various properties of aluminum, various metal additives need to be added to make different grades of alloys. At present, domestic basically use alloy or pure metal form to add. Some domestic aluminum processing plants have already used aluminum alloy additives instead of intermediate alloys. From the use effect, we can see that the additives have all the advantages of intermediate alloys and overcome some shortcomings of intermediate alloys.

　　Aluminum alloy additive product application: add alloying elements in aluminum alloy melting.

　　Product advantages.

　　Metal additives: Aluminum and aluminum alloy additives are much better than intermediate alloys in terms of ease of use, stable elemental yield and economical production methods. It avoids the high melting temperature, which reduces the life of melting furnace; it increases the burning loss of aluminum and alloying elements and reduces the melting productivity, which deteriorates the labor conditions. More seriously, the uneven composition of the intermediate alloy brings a series of difficulties to the control of the content of alloying elements in the future. For most of the civil aluminum alloys, it is an ideal material to replace the intermediate alloy.

　　Instructions for use of aluminum and aluminum alloy additives.

　　Aluminum and metal additives can be added directly to the melting furnace, or to the holding furnace, but must *** be added before refining. In order to achieve the proper alloying element yield, other conditions are needed, as follows: Due to the pure metal addition mechanism, the absorption rate of alloying elements always increases with the increase of temperature.

　　Field experience proves that:Aluminum and metal additives are more sensitive to temperature, especially manganese agent. The temperature of aluminum liquid needs to be controlled at 740±10℃ when the additive is put in, otherwise it will prolong the time of metal absorption.
