Resistance overview
Aluminium is not resistant (D) to Mercury Nitrate at saturated 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
Mercury Nitrate is commonly encountered in water treatment and food processing. Aluminium (Aluminium) is a metal typically used for vessels, heat exchangers, fittings and structural components. The compatibility between these two is therefore an important consideration for engineers and procurement teams selecting containment, transfer, or processing equipment.
Practical recommendation
Aluminium is not recommended for use with Mercury Nitrate. 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 HDPE, LDPE, Nylon (PA) instead, which are rated A for this chemical and offer reliable long-term performance.
Did you know?
The chemical resistance of Aluminium depends not only on the chemical concentration but also on exposure time, mechanical stress, and the presence of other chemicals in the mixture.

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

- 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.
