PREVENT DEZINCIFICATION OF BRASS VALVES
Does dezincification pose a risk of water damage and water losses, which results in high repair costs?
Dezincification must be defined and prevented before our alloy products are affected by it.
#Dezincification is the process of removing zinc from alloys preferentially and undergoes corrosion, a reaction in which metal atoms lose electrons due to an electrochemical reaction. Both can influence the material's composition and subsequently its properties.
Brass is an alloy primarily composed of copper and zinc with a few other elements. If the Brass corrodes, the zinc that strengthens the copper may dissolve.
This leaves the brass with only copper, a structure with low mechanical strength, perforations, and weakened properties❌📈
The following recommendations should be followed to ensure a long-lasting product life cycle 👈
- Brass should not be used in the following situations:
- Water temperatures above 70°C
- Water containing a low bicarbonate content and a high chloride content.
- It is important to be aware that some commercial polishes marketed for copper alloys contain acids that can react with copper, resulting in green-blue compounds.
- Maintain adequate flow.
- Maintain appropriate water treatment.
- Apply cathodic protection.
- Ensure effective conditioning (pH, chloride).
