1,Tabletted additives for alloying aluminum have been in use for recent decades.These tablets(also named alloy compact)can be used as master alloys to produce aluminum alloys.They provide an efficient and economic way of making elemental additions such as titanium,iron.manganese,chromium,zinc,nickel and copper in casthouses world-wide for the manufacture of high-quality aluminium alloys in applications such as rolling ingot for foilstock and canstock,billet for precision extrusions and high-quality foundry casting alloys. Chromium Additive 75%Cr5%Al Nickel Additive 75%Ni5%Al Manganese Additive 75%Mn5%Al Cu-Additive 75%Cu5%Al Fe- additive 75%Fe5%Al 2,100% Manganese ,made in the type of tablet,used for element addition of alloy steel.the effect of using this aditive is the same as that of others but the price is more competitive because of govenmentí»s different policy to the varied kinds of manganese products.3)titanium sponge or titanium powder used for element addition of alloy steel.4)Master Alloysú¿Titanium aluminiumú¼Aluminium Manganeseú¬ allow the introduction of necessary alloying metals into Aluminium alloys easier, and some cases possible.
