Description

technical field [0001] The invention relates to the technical field of alloys, in particular to an aluminum-indium alloy. Background technique [0002] When the power supply with an output voltage above 5,000 volts becomes a high-voltage power supply, and this type of power supply is generally a DC power supply. The output voltage of a general high-voltage power supply can reach tens of thousands of volts, or even hundreds of thousands of volts or higher. High-voltage power supplies have many uses, mainly including high-voltage power supplies for X-ray machines, high-voltage power supplies for lasers, high-voltage power supplies for spectral analysis, and high-voltage power supplies for non-destructive testing. [0003] High-voltage power supplies are generally in harsh working environments for many years, such as high temperature, high humidity, and high salt spray corrosive environments. Not only does it lead to corrosion damage to the circuit board, but also maintenance...
