Energy efficiency sits at the heart of every successful aluminum operation. Whether in melting, holding, or heat-treat furnaces, reducing heat loss and lowering fuel consumption directly translates into cost savings and more stable, consistent processing. That’s why refractory selection matters—and why aluminum producers across North America continue to rely on HWI.
HWI’s commitment to the aluminum industry is built around delivering high-performance lightweight and middleweight refractories engineered specifically to help operators reduce energy usage without compromising durability. These materials offer superior insulation, helping maintain critical temperatures while minimizing heat loss through furnace linings. The result is measurable energy savings, improved temperature uniformity, and enhanced overall furnace efficiency.
What sets HWI apart is the performance of our products. Our lightweight and middleweight solutions are among the best on the market, designed for long service life, excellent thermal efficiency, and dependable performance in the demanding conditions of aluminum processing. They’ve been tested in real-world operations and proven in applications where energy reduction is essential.
From the melt room to downstream thermal processes, aluminum producers count on HWI’s refractories to help lower operating costs and support sustainability goals—without sacrificing reliability.
