Metallography; Metallography Metallography is the most reliable way of identifying the structure of a given product. Through processes such as cutting, mounting, grinding and polishing, a smooth specimen surface is obtained. The purpose for sample preparation is to obtain the material's true structure, without deformation of any kind.

Metallographic preparation of copper Application Notes

Feb 11, 2020· plane grinding with 500# SiC Foil/Paper is sufficient. Large cast parts of copper alloys can be ground with 220# or 320#. It is also important that the force for grinding is low to avoid deep deformation. As indicated in the table with the preparation data, for the soft alloys fine grinding with SiC Foil/Paper with fine grits is recom
