Resistance overview
Aluminium is not resistant (D) to Fluorine and should not be used in direct contact. The chemical is expected to cause rapid degradation, which can include dissolution, cracking, severe swelling, or complete structural failure of the material.
Application context
Fluorine is commonly encountered in metal finishing and laboratory work. Aluminium (Aluminium) is a metal typically used for vessels, heat exchangers, fittings and structural components. Because Fluorine is classified as corrosive, the choice of containment material is especially critical to prevent leaks, equipment damage, and safety hazards.
Practical recommendation
Aluminium is not recommended for use with Fluorine. The D rating indicates that the material will suffer rapid and severe degradation, which may include cracking, dissolution, severe swelling, or complete structural failure. Using this combination risks equipment damage, leaks, and potential safety incidents. Consider using PVC Rigid, ECTFE/ETFE, FEP instead, which are rated A for this chemical and offer reliable long-term performance.
Did you know?
Aluminium was first developed in the 1880s and remains one of the most widely used metals in chemical handling equipment.

About Aluminium
Aluminium relies on a thin oxide layer. Strong acids, strong alkalis and mercury compounds destroy that layer.
Rating scale
- A very good resistance
- B good resistance
- C limited resistance
- D not resistant
- – no data
- K no general statement possible
A rating marked * is an estimate in the source, not a test result. An estimate is given as one value without a temperature.
About this data
The ratings come from the chemical resistance list published by Bürkle GmbH, which compiled them from raw-material manufacturers’ data. They describe laboratory tests on the raw material at 20 °C and 50 °C.
A finished part also sees pressure, mechanical stress, welds and mixtures that a laboratory test does not. Treat the rating as a first filter and test under your own conditions before relying on it.
