Problems solved by technology

However, as an indium alloy, it is far from enough to meet the requirements of only having combustion resistance during smelting. More importantly, the final indium-lithium alloy product must also have satisfactory flexibility, corrosion resistance, and electrical conductivity. and heat transfer performance

Abstract

The invention discloses a flexible In-Li-Re indium lithium alloy with corrosion resistance, high thermal conductivity and high conductivity. The flexible In-Li-Re indium lithium alloy consists of thefollowing components in percentage by weight: 1.6-2.1wt% of Li, 0.3-0.5wt% of Re, 0.6-0.8wt% of Ni, 0.2-0.3wt% of Se, 0.1-0.3wt% of Pd, 0.1-0.2wt% of La and the balance of indium. The indium lithium alloy has high thermal conductivity, high conductivity and corrosion resistance which are not provided in a conventional indium alloy, has flexibility of pure lithium, and has a melting point of 120-140 DEG C. The alloy is great in calorific value, is further applied specifically in an occasion which needs a light apparatus, and is convenient for industrial large-scale application.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to an indium-lithium alloy. Background technique [0002] Indium is a rare metal, and its content in the earth's crust is similar to that of silver, but its output is only 1% of silver. Indium alloys are generally divided into binary alloys, ternary alloys and multi-element alloys. The main indium alloys are: bearing alloys, ferromagnetic alloys, memory alloys, decorative alloys, dental and gemstone alloys. Generally, indium alloys with indium as the main body have relatively low melting temperatures, and are mainly used as some low melting point alloys or solders. Some alloys contain very little indium, and indium mainly plays a role in modification or modification, such as improving the strength of non-ferrous metal alloys, improving their ductility, wear resistance, and corrosion resistance, and changing the color of precious metals. [0003] Indium metal is widely used in hi...
