Resistance overview

Aluminium shows very good resistance (A) to Phthalic Acid at saturated at 20 °C, meaning the material remains essentially unaffected by this chemical under standard laboratory test conditions. 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

Phthalic Acid is commonly encountered in water treatment and metal finishing. 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 Phthalic Acid 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?

In industrial practice, Aluminium components exposed to Phthalic Acid are typically inspected for swelling, discoloration, or loss of mechanical strength as early indicators of chemical attack.

About Aluminium

Aluminium relies on a thin oxide layer. Strong acids, strong alkalis and mercury compounds destroy that layer.

Rating scale

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.
