Embodiment 1
[0018] An aluminum alloy containing Ba and Se with high thermal conductivity for smelting copper-clad aluminum wire at 750 degrees. In terms of weight percentage, the chemical composition of the alloy is: Ba: 0.8wt.%, Ge: 0.5wt.%; Hf: 0.3wt.%, Ru: 0.2wt.%, Os: 0.2wt.%, Se: 0.5wt .%, the balance is aluminum. The preparation method of the alloy: add the above-mentioned raw materials into the atmosphere-protected induction furnace, and use a silicon carbide crucible; induction heat to 750 degrees to form an alloy solution, and use the electromagnetic stirring effect to fully stir for about 10 minutes; put the alloy liquid in After standing at 750°C for 10 minutes, it is cast into the equipment at the same level as the hot top for semi-continuous casting into the required square and round ingots, with the ingot moving down at a speed of 14m / min. The ingot can be used as extrusion raw material for extrusion to prepare aluminum wires of various diameters. Copper-clad aluminum wire...
