Diabase is a hypabyssal rock that is interspersed throughout the primary rock in Sweden. Diabase was formed when magma from the earth’s interior penetrated into cracks in the primary rock and then solidified. The diabase has been compressed by the surrounding rock over a period of 800-1,200 million years. Diabase is consequently an extremely tightly compressed and impact-resistant material, which makes it suitable for constructions that require the highest dimensional stability.
Unique properties
The mechanical properties of Diabase are significantly better and the water absorption is much lower than most types of granite, making diabase ideal for surface plates, components for measuring machines and machine constructions where precision and external factors must be eliminated to an absolute minimum.
Alternative options
Diabase is the material of choice if no compromises can be made. The material is more expensive than granite, which can be used instead if the requirements on precision and stability are not as high.
