Embodiment approach 1

[0034] The palladium alloy provided by Embodiment 1, its components are expressed in parts by weight, and consist of the following substances:

[0035] Palladium accounts for 99-99.1 parts, ruthenium accounts for 0.05-0.3 parts, and copper accounts for 0.2-0.85 parts.

[0036] Embodiment one enumerates the embodiment below and illustrates:

Embodiment 1

[0038] The palladium alloy provided by Embodiment 1 of the present invention consists of the following materials:

[0039] Palladium accounts for 99.1 parts, ruthenium accounts for 0.08 parts, and copper accounts for 0.82 parts.

[0040] The palladium alloy that this embodiment one provides, the weight percent of each component is:

[0041] Palladium accounts for 99.1%, ruthenium accounts for 0.08%, and the rest is copper.

[0042] In the embodiment of the present invention, by adding the trace element ruthenium to the palladium alloy, the crystal grains of the palladium alloy are refined, thereby improving the strength, toughness and ductility of the palladium alloy; adding copper to the palladium alloy increases the hardness and adhesion of the palladium alloy sex. Experiment shows: the palladium alloy that present embodiment provides, in the process of cold rolling, beading, wire drawing, phenomenon such as no bubble, wrinkling, peeling, the finished product rate of makin...

Embodiment 2

[0045] Palladium accounts for 99.1 parts, ruthenium accounts for 0.2 parts, and copper accounts for 0.7 parts.

Abstract

The invention provides a palladium alloy and a production method thereof, wherein the palladium alloy comprises the following components: 99-99.1 parts by weight of palladium, 0.05-0.3 part by weight of ruthenium and 0.2-0.85 part by weight of copper. The production method can improve the toughness, the ductility and the strength of the palladium alloy.

Description

technical field [0001] The invention relates to the technical field of precious metal processing, in particular to a palladium alloy and a production method thereof. Background technique [0002] The processing of precious metal woven chain jewelry includes processes such as cold rolling, wire drawing, and chain weaving. In these processing processes, in order to avoid a large number of fractures, blisters, and layers of precious metal alloys, the precious metal alloy is required to have high strength and toughness. , and ductility and other properties. [0003] In the prior art, when producing full palladium woven chain jewelry, all use full palladium alloy wire rods, and the parts by weight of the full palladium alloy are: palladium accounts for 99 parts, copper accounts for 0.6 parts, zinc accounts for 0.1 part, and nickel accounts for 0.3 parts , cold rolling and drawing the strip foot palladium alloy (pd990) into a wire rod with a diameter of 0.2-0.8mm, and then make t...
