Copper Disc Single Crystal

There are 351 variations of Goodfellow's Copper Disc Single Crystal product. Single crystals like these copper discs are highly pure materials with no grain boundaries and a specific crystallographic orientation. The purity and crystalline structure make them ideal for applications in physics research and x-ray spectroscopy. For example, copper single crystals can be used as monochromators to select a single wavelength of x-rays for diffraction experiments. The lack of defects also allows accurate investigation of the intrinsic properties of copper. With 356 orientations available, researchers can select the crystal direction matched to their experimental needs. The range of Copper Disc Single Crystals from Goodfellow facilitates fundamental materials research across many scientific fields.
