Metals & Alloys Testing & Analysis

Metals & Alloys Testing & Analysis

Metals reveal their history through their structure. The correct alloy, proper heat treatment, a consistent grain structure, and a high-quality weld are what separate a reliable component from one that fails in service. MatX Lab analyzes metals and alloys to verify composition and grade, examine microstructure and hardness, assess weld quality, and identify the root cause of fracture, fatigue, or corrosion. From incoming materials to failed parts, our testing shows what the metal is and how it is likely to perform.

What We Analyze in Metals & Alloys

Metal and alloy testing helps answer a few key questions: what the material is, whether it has been processed correctly, how strong and hard it is, and how it performs in service. The same tests used to check new materials can also help uncover the reason a component failed.

• Alloy composition and grade verification.
• Grain size, phase, and inclusion content.
• Hardness and heat-treatment condition.
• Tensile, impact, and fatigue properties.
• Corrosion resistance and coating integrity.
• Weld and heat-affected-zone quality.

How We Test Metals & Alloys

Metals work usually pairs composition and microstructure with mechanical or corrosion methods, and we scope the combination your question needs. The methods below are the ones we reach for most, and each links to its own page.

Elemental Analysis:

Identifies unknown metals and verifies the alloy's grade and composition, from significant elements to trace levels. This is how you can check a material against a certificate or identify an incorrect alloy mix-up before it is put into production.

Imaging & Microscopy:

Reveals grain structure, phases, inclusions, coating thickness, and weld quality through metallographic cross-sections. It also provides fractography, reading a fracture surface to show how and why a metal broke.

Mechanical Testing:

Measures tensile strength, yield, elongation, hardness, and impact toughness. These are the numbers that tell you whether a metal meets its mechanical specification and how it behaves under real load.

Structural Characterization:

Uses X-ray diffraction to examine phase, crystal structure, texture, and residual stress in metals. This helps confirm that heat treatment has produced the expected structure and identifies residual stresses that can contribute to cracking or early failure.

Corrosion & Environmental Testing:

Evaluates general corrosion, pitting, and stress-corrosion behavior in service-like conditions. It shows how an alloy or a coated part holds up over time, not just on day one.

Failure Analysis:

Brings together fracture analysis, microstructure examination, and composition testing to find out why a part failed. The investigation can show whether the cause was overload, fatigue, corrosion, or a material defect, with conclusions supported by the test results.

Surface Analysis:

Examines oxides, coatings, surface contamination, and surface chemistry that affect adhesion, corrosion, and wear. It is especially useful when the condition of the surface has a greater impact on performance than the material beneath it.

Industries That Rely on Metals & Alloys Testing

Metal testing is used in many industries where parts need to be strong, reliable, and built to last. Every application has its own challenges, but the goal is usually the same: to check the material, understand its structure, and make sure it can perform the job it was made for.

Standards & Test Methods

Metals testing is method-driven, and your specification usually names the standard. Where an applicable standard exists, testing is aligned to it and cited in your report. We align to the method your specification requires and document it.
