Kanthal AB

Kanthal Globar(r) SD silicon-carbide (SiC) heating elements, have high mechanical strength, a lower rate of reaction with the process atmosphere, longer life potential and have been designed for maximum performance in a wide range of high-temperature applications. The elements are extruded from a closely controlled blend of high purity, alpha-SiC grain, which is then recrystallized at over 2500 C (4530 F) to form a strong, self-bonded structure, with uniform heating characteristics. Manufactured in one-piece or three-piece construction, depending on the application, and in a range of sizes, the elements can be supplied as straight rods or as multileg elements. Special glazes and coatings are available for added protection in aggressive furnace atmospheres.
