Surface corrosion can be caused by exposure to moisture, humidity, or improper storage techniques. Regular cleaning and proper storage can prevent surface corrosion from occurring.

Pitting corrosion

Pitting corrosion is more severe than surface corrosion and appears as small pits or craters on the metal surfaces. Pitting corrosion is often caused by prolonged exposure to corrosive substances or neglecting proper cleaning and maintenance routines. Preventing pitting corrosion requires regular inspection, cleaning, and the use of protective coatings.

Galvanic corrosion

Galvanic corrosion occurs when two different metals come into contact, creating an electrochemical reaction. This type of corrosion is commonly seen in firearms with mixed metal components, such as steel and aluminum.

To further understand galvanic corrosion, here’s an insightful discussion from Brownells’ ‘Smith Busters’ series:

“Galvanic corrosion in itself is a real thing but it’s not something you need to worry about here. What it is, is a type of corrosion that happens between two dissimilar metals, and it requires those two metals to be conductive in order for it to occur. Anodized aluminum and AR-15 upper receivers are going to be type III hard-code anodized, which is not conductive” – Stephen Caleb, Brownells.
