Cleaning heavy aluminum corrosion

While maintaining geophysical equipment placed out in the field, you may find some aluminum alloys are heavily corroded in case of contact with water (Or worst if battery leakage). That can be the case when you return for maintenance and revision, maybe months after last installation or visit. Pure aluminum is usually quite resistant to corrosion. But aluminum alloy castings are more susceptible of heavy corrosion. Aluminum alloys with other metals are meant to be stronger than pure aluminum. It depends on the type of alloy whether it is more…
