Can aluminum high pressure die casting automotive parts work for a long time in high humidity, chemicals or other corrosive conditions?

Aluminum high-pressure die-casting automotive parts can work for a long time under high humidity, chemical substances, or other corrosive conditions to a certain extent, but the specific performance depends on various factors.
Aluminum alloy die-casting parts have good corrosion resistance to common corrosive media, thanks to their special alloy composition and manufacturing process. Aluminum alloy die castings can maintain long-term stability and durability in humid or corrosive environments, ensuring the normal operation of automotive parts. In addition, aluminum alloy also has good thermal conductivity, which can effectively dissipate heat. This is particularly important for automotive parts that work under high humidity and corrosive conditions, as it helps prevent performance degradation or damage caused by overheating.
However, it should be noted that although aluminum alloy die castings have excellent corrosion resistance, their performance may be affected under certain extreme conditions, such as strong acid, strong alkali and other highly corrosive environments. In addition, aluminum alloys have relatively low surface hardness and fast wear rate, which may also affect their long-term service life under high humidity and corrosive conditions to some extent.
In order to extend the service life of aluminum high-pressure die-casting automotive parts under high humidity and corrosive conditions, some protective measures can be taken. For example, appropriate surface treatment such as passivation treatment can be applied to parts to enhance their corrosion resistance and wear resistance. In addition, aluminum alloy materials with higher corrosion resistance can also be chosen, or special processes and technologies can be used in the design and manufacturing process to improve the corrosion resistance of parts.
