Aluminium-tungsten System Intermediate Alloy and Preparing Method

The invention is an Al-Wu system medium alloy and preparing method.

Its components (wt%): Wu 10-75, Nb 0-75, Mo 0-75, Ti 0-20 and the rest Al. It can adopt out-furnace ignition smelting: the drying temperature of the raw material 70-80 deg.C, when mixing, add with burden residue accounting for 5-15% of total weight of the raw material; also adopt medium-frequency furnace melting: when mixing according to the above proportion, add with antioxidizer and fluxing agent.

The smelting is stable, avoiding the phenomenon that the smelting current is sometimes high and sometimes low. When preparing Ti alloy, it is able to add the Wu-Al system medium system in alloy package mode.
