Combat® Boron Nitride Powder is the lubricant of the future for the aluminum extrusion industry. Its lubricity, economy, and ease of application far exceed those of other more commonly used lubricants today.
The lubricity of boron nitride is unmatched. Experience has shown that boron nitride need only be applied to every 3 - 5 billets. The quantity used is easily controlled, and the billet usually transfers enough to the dummy block that no further lubricant is required.
