According to GE, the new BN coatings help aluminum and other processors reduce their cost of operations in several ways. They protect the transport surfaces from attack by damaging molten metal, thereby extending the life of dies and molds. They provide good metal release properties, minimizing the time and expense of removing metal build-up during and after a cast. Additionally, the high-purity coatings offer processors protection against contamination in their products. Grades LPC and TPC both contain boron nitride powder that remains chemically inert to 850°C, preventing contamination in metals and improving finished metal quality.
