It has excellent properties of high fire resistance, high mechanical strength, low thermal expansion rate, and high thermal conductivity!
High-alumina refractory brick "MR-8" is a refractory brick that contains more than 50% alumina (Al2O3). It is manufactured using specially selected raw materials, with particle size adjustment, high-pressure molding, and high-temperature firing, resulting in a product with particularly high hot strength, excellent resistance to erosion, and outstanding spalling resistance. In particular, the MR series is a high-alumina refractory brick made from mullite-based raw materials, which has been well received for use in the high-temperature areas of furnaces. *For more details, please download the PDF or feel free to contact us.*

Company information
Our company has been engaged in the manufacture and sale of refractory bricks (refractories) that are "shaped refractories with a service temperature of over 1500°C and unshaped refractories, refractory mortars, and refractory insulating bricks with a maximum service temperature of over 800°C" for many years. While we have primarily focused on sales for industrial furnaces, we began developing and selling the "Easy Arch Stone Oven" in 2010, which has increased opportunities for the general public to appreciate the excellence of refractory bricks. Moving forward, we will continue to face refractory bricks with great passion. Please feel free to contact us with any inquiries.
