Embodiment 1

[0044] (Example 1, the manufacturing method of silver tin oxide indium oxide contact alloy material)

[0045] This embodiment is a method for manufacturing a silver tin oxide indium oxide contact alloy material, comprising the following steps:

[0046] ①Smelting: Melting the ingredients at a preset temperature, the ingredients are as follows:

[0047] Sn: 5.1%;

[0048] In: 1.5%

[0049] Rare earth additives: 1.5%;

[0050] The rest is Ag;

[0051] Above-mentioned each content is mass percentage content;

[0052] The ingredients are melted at 1400°C;

[0053] During the smelting process, heat the furnace to 1400°C, first add Ag, after it melts, then add Sn, In and rare earth, and keep stirring throughout the smelting process to make the atoms fully diffuse to form solid solution and alloy In this embodiment, by adding an appropriate amount of rare earth and In, it can be better distributed in the silver matrix, and the maximum drop of the starting temperature and the end...

Abstract

The invention discloses a method for manufacturing silver tin oxide indium oxide contact alloy material and a manufactured alloy thereof. The method comprises the following steps of: (1) smelting, namely smelting ingredients at the preset temperature, and continuously stirring in the smelting process; (2) casting into round ingots and turning external surfaces thereof; (3) performing hot rolling and cold rolling to form sheets; (4) performing oxygen-increasing treatment on the sheets in an inner oxidation furnace; (5) crushing and performing high-energy crushing treatment; (6) performing hot extrusion to prepare wire blanks; (7) drawing and annealing; and (8) using the obtained materials as finished products. The alloy comprises the following components in percentage by mass: 5.1 to 6.8 percent of Sn, 1.50 to 3.0 percent of In, 1.50 to 2.50 percent of rare earth additive and the balance of Ag. The method for manufacturing the silver tin oxide indium oxide contact alloy material has the advantages of simplified technology, easy implementation and excellent product performance.

Description

technical field [0001] The invention belongs to the technical field of alloy manufacture, and in particular relates to a method for manufacturing a silver tin oxide indium oxide contact alloy material and the alloy produced therefrom. Background technique [0002] With the development of information electronics, automation, automobile and aerospace technology, there is an increasing demand for miniaturized, high-power and high-reliability electrical appliances, switches and other electromechanical components, and the requirements for their performance indicators are getting higher and higher. Silver tin oxide rare earth contact material is a new type of non-toxic electrical contact material that has developed rapidly in recent years. It has the advantages of good thermal stability, arc erosion resistance and strong welding resistance. It is currently used in contactors, relays, etc. It is an ideal material to replace toxic silver cadmium oxide in switches. In 2003, the Chin...
