Hex-Boron Nitride ( HBN ) Powder

Hexagonal Boron Nitride (HBN) is widely used to reduce friction in industrial applications, but it has only recently been adapted to bullets. The latest and greatest bullet-coating material, HBN is ultra-slippery, goes on clear (not powdery), and will not combine with moisture or potentially harm barrel steel. HBN also can withstand extremely high temps (1000° C). Many users feel HBN is cleaner to work with than Moly or WS2, and has fewer health risks.

Watch this method for a new way of applying HBN to your bullets!

 

 

Hexagonal Boron Nitride (hBN) is also known as White Graphite, has similar (hexagonal) crystal structure as of Graphite. This crystal structure provides excellent lubricating properties. hBN is much superior to Graphite and has following characteristics:

•Excellent Lubricating Properties due to low Coefficient of Friction at 0.15 to 0.70
•Good Chemical Inertness
•Electrical Insulator
•Thermal Conductor (result: better heat dissipation)
•High Temperature Stability, 1000o C in Air, 1400o C in Vacuum and 1800o C in Inert gas
•Low Thermal Expansion
•Low Dielectric Constant
•High Load bearing properties
•Non-Wetting: hBN is not wetted by Glasses, Salts and (most) metals, therefore it provides strong resistance to chemical attack Easy Machineability (in hot pressed state). Complex shapes can be machined from hot pressed structure.

Standard sample size is .4oz. 0.4oz is about 1/3 cup of powder

At 8 grains per 400 rounds, this will go a long way! 0.4oz = 170 grains = Enough powder for about 8000 rounds.

hBN, 98% Pure, APS: 0.5 micron

These are typically applied by tumbling/impact media. Either steel or ceramic is fine. Just as long as it is clean media and your bullets are free from oil prior to applying. EXCELLENT SUBSTITUE FOR MOLY OR WS2

Hex boron nitride power (hBN) is 98% Pure, APS: 0.5 micron. At this particle size, this powder is also used as a suspension when mixed with alcohol as bore treatment (bore treatment link). This size is also very sensitive to water vapor, despite what others say. It's particle size is what makes it react with water. To help prevent clumping, each unit is packed with a desiccant.
