Boron Carbide

Boron Carbide is one of the hardest man-made materials available. Boron Carbide also has a low thermal conductivity (29-67 W/mK) and an electrical resistivity ranging from .1-10 ohm-cm. This material is ideal for a wide range of applications because of an excellent strength to weight ratio, low thermal conductivity (29-67 W/mK), and an electrical reistivity ranging from .1-10 ohm-cm. Through research and development, APS Materials, Inc. has engineered a unique and highly successful process yielding a high purity coating utilizing inert or vacuum plasma spray techniques. This material yields an extremely hard surface resistant to wear, abrasion and erosion.

For example:

Blasting Nozzles

Dielectrics

Through cooperative research and development between APS Materials, Inc. and a semiconductor manufacturer, APS has perfected the previously difficult process of applying aluminum oxide to an aluminum substrate. Aluminum oxide is currently in production for the semiconductor industry and features enhanced characteristics as a result of the unique APS process, including a superior tensile strength of 7505 psi or better, increased quality of dielectric properties, and increased density that allows the surface to be ground to a superior finish of 10 microinches or better. The process is executed under complete automation and process control to help eliminate risk of contamination and inconsistency.
