B4C – CAS# 12069-32-8
Boron carbide (𝐵4𝐶) is an extremely hard synthetic material, ranking as the third hardest known substance.

ABSCO offers Boron Carbide in:

• Grit
• Powder
• Fabricated Components

Thanks to its exceptional hardness, high strength, chemical inertness, and low density, Boron Carbide is widely used across multiple industries.

Powder

As an abrasive medium for grinding, lapping and polishing applications. Material is supplied to international FEPA macro and micro grit sizes or to customer specifications.

For metal matrix composites, we are able to supply Boron Carbide classified down to near sub-micron sizes. And for non-oxide ceramics, as a Boron source for the production of Borides.

For further fabrication we offer boron carbide powder as feedstock for the production of nuclear rods, pellets and shielding components, wear resistant components, nozzles for abrasive cutting or blasting, and ballistic armour.

Grit

Boron carbide grit is used as an additive in shielding materials for neutron absorption. Components made from this grit are commonly applied in neutron beam collimation and in parts requiring exceptional wear resistance.

The unique properties of B4C make it essential in defence, aerospace, and manufacturing industries, where both extreme durability and weight reduction are critical. Typical applications include abrasive blasting media, wear-resistant machinery components, and lightweight armour systems.

Hot Pressed and Sintered Components (Density > 2.48 g/cm³)

For vehicle or body armour we can supply Boron Carbide in the form of hexagons or squares with thickness’s up to 25mm.

For nuclear components we offer Boron Carbide to individual customer drawings and specifications. A range of machining operations, e.g., edge chamfering, holes and bonding can be applied as required.

For wear resistant and blasting nozzles ABSCO Limited supplies a range of standard Boron Carbide nozzles or nozzles produced to individual customer drawings.
