Reloading bullet tumbling Boron Nitride (hBN) Powder Kit

Reloading bullet tumbling Boron Nitride (hBN) Powder Kit

This is for a complete tumbling kit.  Kit will work either with vibration or tumbler methods.  We have put it all together for you.  Save time, save money on shipping, no extra waste.  Should be plug and play, ready to go.  All you need need is your application of choice. 

 

Expected yield is 10K of coated bullets .30 cal in size.

 

 

1 oz of Hex-Boron Nitride (hBN) Powder Powder

APS: 0.5 micron (important size.   -5 mesh is larger and less reactive)

1x 500ml Tumbling Bottle with screw on cap

2lb of new jewelry mix steel tumbling media

2x measuring spoons

Instructions for application 

 

 

 

Should be plenty enough for you to run your experiments to see if you like this coating and not have to drop $100 for the 1lb price.

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.


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. We do not carry the “nano” size particle (70 nm) as it is smaller than the pores of your skin and can be absorbed through contact. If you breathe a cloud of this in, it will easily coat your entire airway and lungs which is not in a human’s best interest. Therefore, we were highly suggested from our supplier not to use this particle size for liability concerns. Some people just do not understand plain anatomy and physiology.

 

Because of additonal weight, this will have to be shipped via priority mail.
