A composite plate for large surface-area wear protection is described, in which a basic plate of relatively soft, tough material is soldered on at least one wear plate of hard, brittle cast material. In this, the solder layer does not bond the basic plate to the wear plate over its whole surface; rather, a multiplicity of exposed points remain, which are statistically uniformly distributed over the overlapping surface of the basic plate and wear plate and the average surface area of which exceeds 2 cm<2>. The total surface area of the exposed points may amount to up to 60% of the overlapping surface area between the base plate and wear plate. Composite plates of this kind can be particularly economically produced without detracting from their use, in particular without the risk that individual fragments are released with the fracture of the wear plate (Figure 1). <IMAGE>
