High Quality SK30 SK32 SK34 SK36 Refractory Brick and Fire Clay Brick with Low Thermal Conductivity for Furnace
Leadsun produces a comprehensive range of fire clay bricks consisting of 30–65% alumina, all of which exhibit excellent strength. For more arduous environments, we offer a hand-fired "super duty" fire clay brick with a very high mechanical strength.
Typically, our firebrick range is based upon flint clay, giving it both a low iron and low alkali characteristic. Resistance to thermal shock, abrasion, chemical attack, and reducing atmospheres are just some of the key criteria determining the choice of product within each application. A wide range of sizes are held in stock.
