Can anodized aluminum pump heads come into contact with high-temperature fluorides?

Anodized aluminum pump heads may pose certain risks when in contact with high-temperature fluorides, and direct contact is not recommended.
Anodized aluminum is an aluminum material that has undergone secondary processing and is coated with a dense oxide film on its surface. This film can prevent further oxidation of aluminum and enhance the surface's corrosion resistance. However, fluoride may decompose or react with other substances at high temperatures, and this change in chemical properties may cause fluoride to corrode contact materials. Especially when fluoride is in a high temperature state, its activity is enhanced and it is more likely to react with the contact material.
For anodized aluminum pump heads, although the oxide film on their surface has a certain degree of corrosion resistance, prolonged or high-temperature contact with fluoride may still cause damage to the oxide film, which in turn can corrode the pump head material. This corrosion may not only affect the performance and service life of the pump head, but also pose a threat to the overall safety and stability of the system.
Therefore, in order to ensure the normal operation and safety of the system, it is recommended to avoid direct contact between the anodized aluminum pump head and high-temperature fluoride. In practical applications, corresponding isolation measures can be taken or other high-temperature and corrosion-resistant materials can be used to replace the anodized aluminum pump head to ensure the stability and safety of the system.
