Glacier Vandervell has highly specialised material scientists working in its research
laboratories where bearing alloys can be closely examined to ensure optimum material
microstructure. Micrographs of the full range of Glacier Vandervell materials, as illustrated
here, are prepared and examined using state of the art microsection preparation
equipment and optical and Scanning Electron Microscopy.
