| 148678000 | Noble metals (i.e., silver(Ag), gold(Au), osmium(Os), iridium(Ir), platinum(Pt), ruthenium(Ru), rhodium(Rh), palladium(Pd)) or alloy base thereof | 6 |
| 20100024930 | ELECTROFORMING METHOD AND PART OR LAYER OBTAINED VIA THE METHOD - The invention concerns an electroformed gold alloy part, characterized in that the gold alloy is made up of 88 to 94% by weight of gold, x % by weight of copper and/or silver, and 2x % by weight of zinc, x being comprised between 2 and 4. | 02-04-2010 |
| 20120000582 | TREATMENT OF BORON-CONTAINING, PLATINUM GROUP METAL-BASED ALLOYS - Castings made of boron-containing alloys based on at least one platinum group metal are treated by thermal ageing in the presence of oxygen and at temperatures below the melting point of the alloy. This enables the alloys to be processed at temperatures customary in the jewelry industry. The treated castings can also be processed into medical technology products. | 01-05-2012 |
| 20130153097 | GOLD ALLOY WITH IMPROVED HARDNESS - The invention concerns a gold alloy. | 06-20-2013 |
| 20130213536 | METHOD AND APPARATUS FOR MANUFACTURING METAL MATERIAL AND METAL MATERIAL - The present invention provides a method for manufacturing a metal material. The method comprises a temperature increasing step of increasing the temperature of a silver material having undergone final plastic working to 700° C. or more and less than a melting point of the silver material in a vacuum or a helium gas atmosphere, a heating step of maintaining the silver material at 700° C. or more and less than the melting point, and a cooling step of cooling the silver material to room temperature in a vacuum or a helium gas atmosphere. For a part of the period of the heating step, the silver material is heated in a mixed atmosphere in which hydrogen gas is mixed with helium gas. | 08-22-2013 |
| 20140299240 | HEAT TREATMENT JIG AND METAL WIRE HEAT TREATMENT METHOD - The present invention provides a heat treatment jig. A metal wire as a heat treatment target is to be wound around the jig. The jig comprises a cylindrical tubular body whose outer wall surface has a helical groove formed along a circumferential direction to wind the metal wire. A depth of the groove is larger than a length at which the metal wire will isolate from the groove when the metal wire wound along the groove at room temperature is thermally expanded by being heated to a predetermined heat treatment temperature. | 10-09-2014 |
| 20140345758 | HIGHLY HEAT-RESISTANT AND HIGH-STRENGTH Rh-BASED ALLOY AND METHOD FOR MANUFACTURING THE SAME - The present invention is a heat-resistant material comprising a Rh-based alloy, wherein the Rh-based alloy is a high heat-resistant and high strength alloy comprising a Rh-based alloy where Al and W as essential additive elements are added to Rh (0.2 to 15.0 mass % of Al, 15.0 to 45.0 mass % of W and Rh as the remainder), and a γ′ phase (Rh | 11-27-2014 |
