Release agents in aluminum casting and lubricants in aluminum extrusion. Aluminum casting involves high temperatures and high reactivity. Molten aluminum is typically processed at approximately 650–800 °C. In extrusion, on the other hand, temperatures of approximately 400–550 °C act on the aluminum billet, accompanied by very high extrusion forces.

A major challenge for the aluminum industry—one that Henze BNP’s hexagonal boron nitride products are well-equipped to meet! Hexagonal boron nitride is a high-performance material offering a unique combination of thermal stability, chemical resistance, and excellent sliding properties.

Typical applications:

• Chemically inert process partner for aluminum alloys
• Schutz- und Trennschichten an Gießwerkzeugen, Gießrinnen oder Kokillen
• Coating of a die, press disc, or aluminum billet
• Electrostatic dry lubrication
