Material analysis according to AMS 2249 in the laboratory

Meeting the chemical control requirements for alloys

In demanding industries, particularly aerospace, compliance of an alloy’s chemical composition determines material acceptance, process control and supply traceability. AMS 2249 sets out the chemical control limits applicable to wrought nickel- and cobalt-based alloys. A material analysis makes it possible to compare measured contents with the requirements applicable to the grade, batch and customer specification. It helps identify a composition deviation, secure material receipt or document a quality investigation.

Defining an analysis plan suited to the grade

The inspection plan is defined based on the designation of the alloy, the applicable specification and the purpose of the test. It may cover the main alloying elements, as well as residual elements or impurities subject to specified limits. The quality of the sampling and its representativeness are decisive for obtaining usable metallurgical analysis.

Using analytical methods suited to metals

The choice of method depends on the elements being investigated, the target content levels, the metal matrix and the amount of sample available. The Filab laboratory selects analytical methods suited to the characterization objective and prepares the test specimens or samples required for measurement.

Securing sample collection and identification

A part, production offcut, coupon or chips can be analyzed depending on the requirements and selected method. Each sample must be identified, linked to its declared grade and accompanied by the available information: batch number, metallurgical condition, product form, specification and purpose of the control.

Carrying out an AMS 2249 analysis at the Filab laboratory

The Filab laboratory supports industrial companies with their analysis according to AMS 2249, from defining requirements through to issuing results. The teams take into account the nature of the material, the shape of the sample, the elements to be measured, and the standard provided by the client. The service can be integrated into a broader metallurgical analysis process to characterize the material and support quality control decisions.

The Filab laboratory also supports you with the following services:

Obtaining interpretable results for material control

Results are presented as content levels for each element to facilitate comparison with the stated limits. In the event of an apparent non-compliance, the Filab laboratory can help identify relevant additional checks, depending on the industrial context and available documentation.

Supplementing chemical analysis with metallographic examination

When justified by the investigation, composition analysis may be combined with examinations of structure, surface or defects. Observations made in the laboratory using SEM provide, in particular, additional insight into the metallurgical condition of a part or product.

The Filab laboratory also supports you with:

Adapting the request to production constraints

Before shipment, the Filab laboratory teams can clarify the required packaging, material quantity and technical information to provide. This preparation helps efficiently direct the material analysis and reduce additional exchanges before testing.

Benefit from decision-oriented support

Filab laboratory combines expertise in material characterization, test program definition and reporting of actionable results for quality, procurement and production teams. To launch your project, send your specification and material information, discuss the inspection plan, then receive a proposal tailored to your analysis needs.

Frequently asked questions

How can the chemical compliance of a nickel- or cobalt-based alloy be verified according to AMS 2249?

AMS 2249 concerns the chemical composition control limits for certain wrought nickel- and cobalt-based alloys. At the Filab laboratory, the measured contents are compared with the requirements of the applicable specification provided with your request.

Which elements can be controlled as part of an AMS 2249 analysis?

The elements controlled depend on the alloy grade and the version of the applicable specification. The Filab laboratory defines the analysis to be performed based on your material reference, specifications and expected control limits.

Which techniques are used to analyze the composition of a metal alloy?

The Filab laboratory selects analytical methods according to the matrix, the elements to be quantified, the expected limits and sample availability. Metallographic examinations can supplement chemical analysis when a material investigation is required.

Which sample should be submitted for an AMS 2249 analysis?

Filab laboratory can test different forms of metal samples, subject to their representativeness and quantity. Provide the material reference, applicable specification, purpose of the inspection and batch identification to prepare the analysis.
