Resistance overview
The resistance of Aluminium to Ammonium Nitrate is concentration-dependent. Across the 2 tested concentrations (10 %, saturated), the 20 °C rating ranges from A at lower concentrations to B at higher ones. This means engineers must verify which concentration their process actually involves before relying on a single rating. The rating remains stable between 20 °C and 50 °C, which means this material can also handle moderately elevated process temperatures without additional risk.
Application context
Ammonium Nitrate is commonly encountered in chemical storage and electroplating. 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 can be used with confidence for Ammonium Nitrate containment and handling. The A rating indicates that the material shows no significant change in weight, dimensions, or mechanical properties after prolonged contact under test conditions. This holds true at both 20 °C and 50 °C, giving a good safety margin for typical process environments.
Did you know?
When choosing between metals for Ammonium Nitrate service, engineers consider not just the resistance rating but also factors such as permeation rate, creep resistance, and weldability.

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.
