BQCIS

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

Instrument Calibration

Calibrating the ET system with certified conductivity or permeability standards to ensure accurate readings across all test samples.

Comparative Sorting / Measurement

Measuring absolute conductivity (in %IACS) or comparing probe responses against reference standards to segregate alloys, heat treatments, or hardness conditions.

Key Benefits of ET for Sorting

Extremely Fast

Extremely Fast

Provides near-instant readings for rapid material segregation and verification, even in high-throughput environments.

Non-Destructive PMI

Non-Destructive PMI

Confirms material type, conductivity, and heat treatment without cutting, altering, or damaging the test component.

Versatile Applications

Success Story

ET Conductivity Sorting Prevents Aluminum Alloy Mix-Up

The Challenge:

An aerospace manufacturer needed to verify large batches of aluminum bars for potential alloy mix-ups between 2024 and 7075, which appear visually identical.

Our Solution:

BQCIS performed conductivity testing using certified reference standards. Distinct readings quickly identified alloy variations across the batch.

The Result:

The ET system successfully segregated incorrect alloys before machining, preventing costly rework and ensuring compliance with aerospace strength requirements.
