Abstract

The invention discloses a corrosion-resistant gold-based precise hardware material. The corrosion-resistant gold-based precise hardware material consists of gold, silver, copper, nickel, gadolinium, yttrium, praseodymium and platinum, and the weight parts of the components of the corrosion-resistant gold-based precise hardware material are as follows: 50-62 parts of gold, 10-17 parts of silver, 8-15 parts of copper, 6-13 parts of nickel, 1-7 parts of gadolinium, 2-8 parts of yttrium, 3-9 parts of praseodymium, and 5-11 parts of platinum. The corrosion-resistant gold-based precise metal material has the characteristics of being high in conductivity, high in thermal conductivity, high in corrosion resistance, high in vulcanization resistance and high in wear resistance.

Description

technical field [0001] The invention relates to a corrosion-resistant gold-based precision hardware material. Background technique [0002] Gold-based alloys are alloys composed of gold as the base and other elements. Gold has low tensile strength, high elongation, and is easy to process. At a temperature lower than its melting point, various pressure processing methods can be used. Various elements can be added to gold to form a gold-based alloy. Due to the different effects of elements, the properties of the alloy vary greatly. Mainly used as electrical conductors, moving contacts, jewelry, springs, potentiometers, coal materials, electric brushes, thermal electrodes, precision resistance materials, etc. The use effect of the existing gold-based alloy materials is mediocre, which cannot meet the current use needs. Contents of the invention [0003] The purpose of the present invention is to provide a corrosion-resistant gold-based precision hardware material with the ...
