Metallography is necessary for the study of the microstructural or constitutive characteristics of a metal or alloy, relating them to the priorities, physical, chemical and mechanical.

There is a lot of information that a metallographic examination can provide, for this it is necessary to obtain samples that are representative and that do not present alterations due to extraction and / or metallographic preparation.

The tooling we have for gray and nodular cast iron is as follows:


Chemical analysis of 22 elements


GB And RC Hardness 


Carbon and silicon



All the product resulting from gray and nodular cast iron is tested in such a way that we guarantee the quantity of the final product.
We have state-of-the-art technology to carry out quality tests
