Why this test matters
Hidden defects can compromise strength, durability, and safety. Macrography helps companies detect issues such as cracks, porosity, segregation, or weld defects before they lead to failure. It supports quality control, process validation, and failure investigation, and applies across metals, plastics, composites, and coatings, wherever a component's internal structure needs to be verified rather than assumed.
How the test works
A sample is examined under a stereomicroscope at low magnification. Before observation, it can be cut, polished, etched, or embedded, depending on what best reveals the structure in question. Our material experts photograph the resulting macrographs and describe their findings in a report, giving you both the visual evidence and an expert interpretation of what it means.
What you learn from this test
The test provides clear visual information about the internal structure and quality of the material. Results reveal grain flow, weld penetration, inclusions, cracks, or manufacturing defects. Companies use this insight to assess process quality, validate manufacturing steps, investigate failures, and support acceptance criteria. The findings enable confident decisions on product reliability, safety, and compliance.
