ifriction.com comments Specific gravity 8.96, Moh hardness 2.0 - 2.75. Improves friction stability, product integrity / appearance and thermal distribution. Decreases the use of other materials in the matrix such as various expensive lubricants, steel fiber, more expensive copper fibers, various metallic components, etc. resulting in valuable cost savings, simplified formulae, improved dispersion in mixing and excellent product appearance/consistency. |
