The other is to make the alloying elements into a master alloy in advance. Then it is added to the aluminum melt in the form of a master alloy. At present, it is more commonly used to add various metal additives to the aluminum melt. In addition, there is a method of adding, that is, adding salts or compounds containing alloying elements, and reducing the elements through the substitution reaction with the base metal and entering the melt.<\/p>\n<p>The purpose of using <a href=\"http:\/\/www.alalloycasting.com\/aluminum-alloy-additives\/\">aluminum alloy additives<\/a>\u00a0is to facilitate the addition of some alloying elements that have a higher melting point and are not easily melted or easily oxidized and volatilized, so as to more accurately control the composition of the aluminum alloy. In addition, the use of a master alloy as a charge can prevent the melt from overheating, shorten the smelting time, and reduce metal burnout.<\/p>\n<p><strong>The aluminum alloys additives used should meet the following basic requirements as much as possible:<\/strong><\/p>\n<p>(1) The melting point should be lower than or close to the melting temperature of aluminum alloy;<br \/>\n(2) The content of alloying elements is as high as possible, and the composition is uniform;<br \/>\n(3) Low content of impurities, gases and non-metallic inclusions:<br \/>\n(4) It has sufficient brittleness, is easy to break, and is convenient for ingredients;<br \/>\n(5) It is not easy to be corroded, and should not be broken into powder when stored under atmospheric temperature and pressure.<\/p>","protected":false},"excerpt":{"rendered":"<p>At present, various master alloys are generally used to replace aluminum alloys additives, because master alloys have a low melting point and are easier to quickly and uniformly melt in the aluminum melt.
