Rapid Material Verification and Sorting
Eddy Current Testing (ET) enables fast, accurate verification of material types and properties by analyzing variations in conductivity and magnetic permeability. Each metal or alloy exhibits a unique electromagnetic signature, allowing precise sorting and identification.
Using calibrated probes and reference standards, the system detects changes in impedance that correspond to specific alloy types, heat treatments, or hardness levels. This allows operators to verify incoming materials, prevent mix-ups, and ensure compliance with design specifications.
BQCIS applies ET conductivity and sorting to streamline Positive Material Identification (PMI) processes for manufacturing, aerospace, and energy sectors— ensuring that only conforming materials enter production or service.
Key ET Sorting Activities
Key Benefits of ET for Sorting
Extremely Fast
Provides near-instant readings for rapid material segregation and verification, even in high-throughput environments.
Non-Destructive PMI
Confirms material type, conductivity, and heat treatment without cutting, altering, or damaging the test component.
Versatile Applications
Detects alloy mix-ups, evaluates hardness and heat treatment, and measures coating thickness or permeability differences.
Portable Equipment
Handheld conductivity meters and ET sorters enable quick, reliable field verification at warehouses or production lines.
Success Story
ET Conductivity Sorting Prevents Aluminum Alloy Mix-Up
An aerospace manufacturer needed to verify large batches of aluminum bars for potential alloy mix-ups between 2024 and 7075, which appear visually identical.
BQCIS performed conductivity testing using certified reference standards. Distinct readings quickly identified alloy variations across the batch.
The ET system successfully segregated incorrect alloys before machining, preventing costly rework and ensuring compliance with aerospace strength requirements.
