M&A Alpha Alumina powders are made to the highest specifications and are used for final polishing of metallographic speciments. Accurately controlled purity levels and particle size distribution assuring you the optimum polishing results. Mix with distilled water to produce a liquid slurry with the desired consistency.
Advantages and Features of M&A Alpha Alumina
-
Improved surface finishes over gamma alumina
-
Less random scratching
-
Higher cutting rates than gamma alumina
-
Much more uniform surface finish
-
Tighter particle size distributions than gamma alumina
-
Low viscosity for easy dispensing
-
Semi-permanent suspensions
​
ALUMINA
The most efficient application is to initially wet the polishing cloth with alumina powder and then to slowly drip or spray the suspension onto the polishing cloth
It is recommended that water be continuously applied to the polishing cloth for several seconds prior to completion of the polishing step. This aids in removing the fine particles which may be electrostatically attracted to the specimen surface.
