Abrasive Grain
Microstructures maximize mineral performance
Tough. Hard. Self-sharpening.
Crystals Improve Wear Rates
Unlike conventional abrasives, such as aluminum oxide and alumina
zirconia, Cubitron grain has a crystalline structure that wears away
in smaller “chunks”. This leaves more mineral available to continue
working and increases the life of the product.

Cubitron Grain Takes the Heat
Platelets Improve Fracture Toughness and Create a
“Self-Sharpening” Mineral
“Self-Sharpening” Mineral
A secondary phase microstructure in Cubitron grains 321 and 324
produces platelets which serve to reinforce the mineral to withstand
greater grinding forces. It also enables the grain to leave a jagged
irregular surface when it does fracture so the fresh cutting
surfaces remain sharp.
produces platelets which serve to reinforce the mineral to withstand
greater grinding forces. It also enables the grain to leave a jagged
irregular surface when it does fracture so the fresh cutting
surfaces remain sharp.
This sharper cutting surface contrasts sol gel mineral without platelets
— which leaves a relatively smooth surface that can result in a larger
contact area with the workpiece surfaces, creating increased frictional
drag, heat buildup, poor cut and potential workpiece damage.

The key to the performance of Cubitron Grain is its unique
microstructure which is a composite consisting of alpha-alumna
crystallites interspersed with a platelet secondary phase.

The microstructure and hardness of 3M Cubitron grain 321 remains
stable even when heated for 12 hours at 1300°C. This thermal stability
is critical to ensure the performance of Cubitron grain 321 is not altered
during subsequent manufacturing processes.
