The manufacturing cost of a sputtering target is reduced and the impurity concentration of the manufactured sputtering target is also reduced. A method of manufacturing a sputtering target includes: surface-treating at least one of a used sputtering target and a scrap material; melting at least one of the used sputtering target and the scrap material after the surface treatment to form an ingot; and manufacturing a sputtering target by subjecting the ingot to forging, rolling, heat treating, and machining.

The invention relates to a method for producing a strip made of an AlMgSi alloy in which a rolling ingot is cast of an AlMgSi alloy, the rolling ingot is subjected to homogenization, the rolling ingot which has been brought to rolling temperature is hot-rolled, and then is optionally cold-rolled to the final thickness thereof. The problem of providing a method for producing an aluminum strip made of an AlMgSi alloy and an aluminum strip, which has a higher breaking elongation with constant strength and therefore enables higher degrees of deformation in producing structured metal sheets, is solved in that the hot strip has a temperature of no more than 130 C. directly at the exit of the last rolling pass, preferably a temperature of no more than 100 C., and the hot strip is coiled at that or a lower temperature.

Disclosed are high-strength aluminum alloys and methods of making and processing such alloys. More particularly, disclosed is a 6XXX series aluminum alloy exhibiting improved mechanical strength, formability, corrosion resistance, and anodized qualities. An exemplary method includes homogenizing, hot rolling, solutionizing, and quenching. In some cases, the processing steps can further include annealing and/or cold rolling.

A vacuum smelting device with mold-temperature control design includes: a chamber body and a cabin door, wherein the chamber body and the cabin door form a vacuum closed space; a smelting crucible disposed in the vacuum closed space for smelting raw materials to a molten metal; a casting mold also disposed in the vacuum closed space for accommodating the molten metal poured from the smelting crucible, and solidifying the molten metal to an as-cast alloy; and a mold-temperature control module surrounding the casting mold for controlling the temperature of the casting mold.

A zirconium alloy is manufactured through melting; solution heat treatment at 1,000 to 1,050 C. () for 30 to 40 min and -quenching using water; preheating at 630 to 650 C. for 20 to 30 min and hot rolling at a reduction ratio of 60 to 65%; primary intermediate vacuum annealing at 570 to 590 C. for 3 to 4 hr and primarily cold-rolled at a reduction ratio of 30 to 40%; secondary intermediate vacuum annealing at 560 to 580 C. for 2 to 3 hr and secondarily cold-rolled at a reduction ratio of 50 to 60%; tertiary intermediate vacuum annealing at 560 to 580 C. for 2 to 3 hr and tertiarily cold-rolled at a reduction ratio of 30 to 40%; and final vacuum annealing at 460 to 590 C. for 7 to 9 hr.

A method of casting an aluminum alloy is provided. The method includes casting a master aluminum alloy having a trisilanol phenyl polyhedral oligomeric silsesquioxanes (TSP) modifier into an ingot and adding the master aluminum alloy ingot into a molten base aluminum alloy to form a modified aluminum alloy. The modified aluminum alloy is heated for a period of time and then cast into a cast component. A variation of the method includes mixing a powdered aluminum alloy with a powdered TSP and pressing the mixture of powdered TSP and powdered aluminum alloy into a compacted preform prior to casting the master aluminum alloy. The compacted preform is melted during the step of casting the master aluminum alloy.

A method for the continuous casting of metal strands. The liquid metal is simultaneously cast via a moulds into metal strands. The moulds each have a narrow side and a broad side. The moulds have a uniform narrow side so that the metal strands have equal thicknesses after casting. At least one of the moulds used has a broad side whose length differs from the length of the broad side of the other simultaneously used moulds. For each mould used, a sprue stone is provided, which is arranged on a casting table and is provided for receiving the starter strands. The casting of the metal strands includes a mould filling phase with a fixed casting table in which a plurality of starter strands is cast into the associated sprue stones. The casting includes a continuous casting phase in which the casting table is lowered and metal strands are cast.

Disclosed are alloys for anodized-quality aluminum sheets with improved surface quality, and methods for making these sheets. The alloys are designed to minimize the formation of cathodic intermetallic particles that result in surface streaks of anodized sheet products formed from the alloys. Further, the alloys allow the incorporation of recycled scrap aluminum in anodized-quality sheets.
