Extrusion of alveolar bricks requires perfect control of the products’ geometry/shape and constancy of the walls (void percentage).
BMI offers a range of high resistance materials for its cores : high chromium steels with specific heat treatment, chromium coating or complex sintered carbides.
BMI cores allow perfect control of the management of brick extrusion. This is due to an outstanding abrasion resistance combined with material fluidity (excellent friction coefficients).
