Eddy Current Testing and Inspection Services for Metal Parts

Eddy current testing can help detect surface and near-surface discontinuities in electrically conductive materials, including cracks, seams, laps, corrosion, and certain material-property variations. It may also be used to assess coating thickness or sort materials in suitable applications. Results depend on the alloy, component geometry, surface condition, probe selection, and the inspection procedure specified for the part.

Eddy current testing is intended for electrically conductive materials, such as carbon steel, stainless steel, aluminum, nickel alloys, copper alloys, titanium, and other conductive metals. The material’s conductivity, permeability, shape, surface condition, and required sensitivity affect method selection. A review of the applicable specification and part configuration helps determine whether eddy current inspection is appropriate for the intended purpose.

No. Eddy current testing is a non-destructive testing method, meaning it can examine a conductive component without cutting, bending, or otherwise damaging it. A probe generates an electromagnetic field and measures changes in response from the material. Because the part remains intact, the method is useful for evaluating material condition while preserving components for shipment, machining, assembly, or service.

Eddy current testing is most effective for surface and near-surface conditions. Effective inspection depth varies with the material, test frequency, probe type, geometry, and discontinuity orientation. Higher frequencies generally emphasize surface conditions, while lower frequencies may provide greater penetration with reduced sensitivity. For internal or deeper flaws, another non-destructive method may be more suitable under the governing specification.

Eddy current methods can support material sorting and identify variations in conductivity or magnetic response when compared with known standards. However, they do not replace chemical analysis, mechanical testing, or full certification review when a specification requires those controls. For critical orders, testing should be selected alongside material traceability and the exact acceptance criteria required by the customer or end-use application.

Provide the alloy or material designation, product form, dimensions, quantity, intended application, applicable drawing or specification, and the condition you need evaluated. Include any acceptance criteria, documentation requirements, and requested delivery date. This information helps define whether eddy current testing is suitable, coordinate the appropriate inspection approach, and align material, testing, and shipping requirements before work begins.

Pricing is customized to the requirements of the job. Key considerations include material type, part size and geometry, quantity, inspection scope, acceptance standard, documentation needs, and turnaround expectations. Providing complete specifications early allows Aero-Vac Alloys & Forge, Inc. to review the work accurately and coordinate a practical testing solution that fits the material order and delivery schedule.

Yes. Aero-Vac Alloys & Forge, Inc. supports material procurement, independent third-party testing, and in-house saw cutting so customers can reduce coordination across separate vendors. Combining these needs can simplify order handling for custom cuts, odd sizes, and specification-driven materials. Testing requirements should be identified before processing and shipment so the correct documentation and inspection steps can be arranged.
