Diamond Lapping Oil Extender

Aluminum Oxide or Alumina – Aluminum oxide or alumina exists in two allotropic forms (1) alpha, which has a hexagonal crystal structure, and (2) gamma, which has a cubic crystal structure. Alpha alumina removes metal faster and is more suitable for rough polishing, while gamma alumina has slower metal removal rates but produces a better finish. Gamma B (0.05 micron) is used for final polishing steps, typically on a Suncloth Polishing Cloth. Aluminum oxide is excellent for most etch-attack polishing methods.

Diamond Compounds and Slurries – Two types of diamonds are offered: monocrystalline and polycrystalline. The most commonly used is monocrystalline. The polycrystalline, is typically used on hard-to-polish materials such as ceramics, tool steels, and super alloys. It has more facets or cutting edges and keeps its cutting ability by being less friable than the monocrystalline. The diamond suspensions are water-based while the compounds contain no water.
