Reliability in service
Resistance is essential to ensure longevity of components exposed to corrosive media.
Overview
What is dezincification?
It is a corrosion process that selectively removes zinc from copper alloys containing zinc, particularly brass. The resulting structure becomes porous and weakened, undermining mechanical integrity and performance.
ISO/IEC 17025:2017 accredited practices and reporting.
Why it matters
Prevent failures, leaks, and damage
Fewer leaks & failures
High resistance helps prevent premature failure, leaks, and structural damage.
Lower maintenance
Strong resistance reduces maintenance costs and extends service life.
Applications
Where it applies
Potable & process water
Systems where brass and other Cu–Zn alloys are commonly used.
Seawater & splash zones
Exposure to aggressive chloride-bearing waters.
Chemical processing
Environments containing water, acids, or other corrosive substances.
Analysis
What we quantify
Depth of dezincification
Measurement of attack depth to gauge severity and risk.
Degree of selective attack
Quantitative assessment of zinc removal and porous layer formation.
