2017 Aluminum Bar Corrosion Resistance is Relatively Poor

The corrosion resistance of the 2017 aluminum bar is relatively poor in its natural state. The main reason is the addition of copper (Cu content 3.5%-4.5%), which makes the alloy prone to electrochemical corrosion in humid or corrosive environments. Compared with other aluminum alloys (such as the 5xxx or 6xxx series), the 2017 aluminum bar relies more on surface treatment or protective cladding to enhance its corrosion resistance.

2017 Aluminum Bar Sensitivity to High-Temperature Environments

When the temperature exceeds 100℃, the 2017 aluminum bar may develop intergranular corrosion tendencies. This is especially true when the material is not clad or surface-treated, as the grain boundaries inside the material are prone to oxidation and corrosion damage. Therefore, in high-temperature applications, usage conditions must be strictly controlled, or protective measures should be adopted.
