Abstract

The invention discloses rose palladium with rose color and brittle failure resistance and a processing technology of the rose palladium. The rose palladium is prepared from the following alloy components by weight percent: 0.3 to 0.5 percent of Be, 0.8 to 1.2 percent of Li, 1.0 to 1.5 percent of Cr, 2.0 to 3.6 percent of Ti, 0.2 to 0.4 percent of C, 4.0 to 4.5 percent of Os, 3.0 to 3.8 percent ofIr, 30.0 to 34.0 percent of Cu, and the balance of palladium. The invention provides the palladium alloy which is not available on market at present and has excellent performance and rose color, so that the varieties of the palladium alloys for jewelries on the market can be greatly enriched.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a palladium alloy. Background technique [0002] The appearance of palladium is similar to that of platinum, with a silver-white metallic luster, bright color and strong ductility. Palladium is one of the rarest precious metals in the world, much rarer than gold. Only a few countries such as Russia and South Africa produce gold in the world, and the total annual production is less than 5% of gold. The appearance of palladium shines with white light, and its purity is very suitable for the skin without causing skin allergies. Palladium is extremely tough, and the jewelry made of it not only has the natural and charming brilliance of platinum, but also can withstand the tempering of the years, looking like new for a long time. [0003] As a rare precious metal with white metallic luster, palladium has a unique temperament. Palladium jewelry has attracted much attention in the jew...
