Mechanical Properties of CVD Diamond

Diamond is known for its extreme hardness. It exhibits an exceptional wear resistance and a low coefficient of friction. These properties make CVD diamond an ideal choice for highly demanding applications such as cutting tools for non-ferrous materials, surgical knives and wear resistant coatings.

We have summarized the main properties of CVD diamond in our "CVD diamond booklet".
