Embodiment Construction

[0012] The new gold alloy material was prepared by the following process.

[0013] According to mass percentage (%): Pd 1~3, Gd 0.2~0.6, the balance of Au to prepare raw materials, vacuum or argon protection melting → ingot 700 ° C / 3h should be treated → cold rolling → 550 ~ 600 ° C / 0.5 h Intermediate heat treatment → finish rolling to obtain a new gold alloy material.

Abstract

An au-alloy is prepared from Pd (1-3 mass %), Gd (0.2-0.6) and Au (rest). Its advantages are the improved elasticity and yield point, low resistance temp coefficient, high recrystallizing temp, and high resistance to creep, electric corrosion and abrasion.

Description

technical field [0001] The invention relates to a novel gold alloy material for precision contacts. Background technique [0002] Gold has the best chemical stability, will not generate oxides and sulfides, and will not generate "brown powder" when it interacts with organic vapors. It has low and stable contact resistance, and good electrical and thermal conductivity. For precision contacts with small contact pressure and low voltage, especially under the conditions of current 1-10μA and voltage 1-50mv, gold is an ideal material, but gold has poor elasticity, low yield point, and easy to undulate welding. Spikes are formed under the action of electric current. Contents of the invention [0003] The object of the present invention is to provide a novel gold alloy material for precision contacts. It can solve the problems of poor elasticity of gold, low yield point, easy undulation welding, and formation of spikes under the action of small current. [0004] The novel gold...
