The Ultra Express 70 High Strength 3100°F Castable from Canadian Forge & Farrier is a premium refractory material designed for high-performance applications. With a remarkable strength of approximately 20,000 psi at 3100°F, this self-leveling, high alumina (70%) castable is ideal for farriers, blacksmiths, and metalworkers seeking durability and reliability.
This product is primarily a fine castable powder with minimal small aggregates, making it perfect for creating smooth, strong surfaces. It's particularly suited for use with ribbon burners due to its excellent flow properties. The Ultra Express 70 is part of a unique group of refractories that gain strength at higher temperatures, ensuring longevity and resilience in demanding environments.
Despite its strength, the product requires very little water for mixing—typically around 8-10%—and transforms into a liquid state after a few minutes of mixing. This feature makes it user-friendly and efficient, even without a vibration table. Additionally, it is highly tolerant of welding flux, preventing penetration and damage.
Whether you're working on forge floors, kilns, or other high-temperature applications, the Ultra Express 70 offers exceptional performance and versatility. Its dense composition means a 50 lb bag covers less area than expected, but its strength and durability more than compensate.
