Electro Abrasives, LLC. manufactures Boron Carbide powders by water classification at our state-ofthe-art headquarters in Buffalo, NY USA. All chemistry and sizing is controlled to meet exact 

customer requirements. All Boron Carbide manufactured at Electro Abrasives, LLC meets or 

exceeds ANSI or FEPA standards for product quality.

Boron Carbide (B4C) is one of the hardest man made materials available. Above 1300°C it is even 

harder than diamond and cubic boron nitride. It has a 4-point flexural strength of 50,000-70,000 psi 

and a compressive strength of 414,000 psi, depending on density. Boron Carbide also has a low thermal conductivity (29-67 W/mK) and has electrical resistivity ranging from 0.1-10 ohm-cm. 

APPLICATIONS:

With its strength to weight ratio and low thermal conductivity, Boron Carbide is ideal for a wide 

variety of applications including blasting nozzles, body armor, ceramic & metal-matrix composites, 

aerospace applications, refractory anti-oxidant, lapping, honing stones, nuclear technology, 

ultrasonic machining, and many others.
