Abstract: A method of manufacturing a member for fastening by joining a nut with a tubular joint portion extending from a main body formed with an internal thread to a panel with a mounting hole for the nut on an aluminum base material. The joint portion has a rotation-preventing portion with a concave and convex shaped outer peripheral surface and a guide portion extending from the rotation-preventing portion to one side. After the guide portion is inserted into the mounting hole, the nut is energized by electrodes in contact with both nut end surface sides. The nut then generates heat, and the periphery of the mounting hole is heated and softened. When the nut is pressurized with the electrodes, the rotation-preventing portion bites into the mounting hole, and the one end portion of the guide portion is swaged to become a retaining portion on one surface side of the panel.

Abstract: A Mg removal agent is composed of a chloride and copper oxide. The chloride contains at least Mg and one or more base metal elements selected from K, Na, and Ca. The chloride contains, for example, 0.2 to 60 mass % of MgCl2 and/or 40 to 99.8 mass % of KCl with respect to the chloride as a whole. The compounding ratio that is a mass ratio of the chloride to the copper oxide is, for example, 0.15 or more. The chloride may be a re-solidified salt or a mixed salt. At least a part of the chloride may be a mineral containing the base metal elements and Mg or a mineral-derived chloride. A preferred example of the Mg removal agent is granular flux introduced into the aluminum alloy molten metal.

Abstract: A metal purifying method having: a local heating step of heating an aluminum-based molten metal in a first region on a molten metal surface of the aluminum-based molten metal; and a local low pressure step of lowering the pressure in a second region on the molten metal surface to a pressure lower than the pressure in the first region. The second region is different from the first region. This allows a specific element to be vaporized from the second region to purify the aluminum-based molten metal. The specific element is one or more of Zn, Mg, or Pb having a saturated vapor pressure higher than that of Al. This is effective not only in a purifying method for removing a specific element from an aluminum-based molten metal but also in a method of recovering a specific element, which can be a resource, from an aluminum-based molten metal.

Abstract: A recycling method for aluminum alloy is capable of offering a recycled Al alloy (melt), in which the Fe concentration is efficiently reduced, while using Al alloy scrap and the like as raw materials. The method includes: a preparation step of preparing a first melt by melting an Fe.Mn-containing material that contains Fe and Mn and an Al alloy raw material; a crystallization step of holding the first melt at a separation temperature at which an Fe compound crystallizes; and an extraction step of extracting a second melt obtained by removing at least part of the Fe compound crystallized from the first melt. The Fe.Mn-containing material preferably has a mass ratio of Mn to Fe (Mn/Fe) of, for example, 2 or more.
