Overview
Assess layered intergranular attack risk in 5xxx aluminium
The ASSET method provides a precise visual assessment of exfoliation corrosion susceptibility—especially relevant for directional microstructures in 5xxx aluminium-magnesium alloys—so you can qualify mill products and extend component life.
ISO/IEC 17025:2017 accredited practices and reporting.
Why ASSET
Predict exfoliation before it compromises integrity
Exfoliation is a lateral form of intergranular corrosion that causes metal to peel away, reducing the effective cross-section and threatening structural integrity—particularly in marine exposure. ASSET delivers reliable insights for alloy development, QA/QC, and service suitability.
Code Classification
Result codes & interpretation
Pitting
Discrete pits present without layered lifting.
Exfoliation
Characteristic layered appearance where corrosion products raise material from the base.
Applications
Where ASSET adds value
Seawater environments
Screen 5xxx alloys for resistance in hulls, decks, and coastal structures.
Load-bearing plate & sheet
Confirm integrity where cross-section loss would be critical.
Process equipment
Support quality control and material selection in corrosive atmospheres.
