Examples include ceramic coatings on turbine blades and ceramic insulators in electrical systems.<\/li>\n\n\n\n<li class=\"\"><strong>Glass:<\/strong> Found in windows, viewports, and some optical equipment. While glass is inherently brittle, laminated or tempered glass can improve its impact resistance.<\/li>\n\n\n\n<li class=\"\"><strong>Cast Iron:<\/strong> Though it exhibits some ductile properties, cast iron&#8217;s brittleness needs to be carefully considered in marine applications. It&#8217;s used in specific components like engine blocks and pump housings due to its good casting properties and wear resistance.<\/li>\n\n\n\n<li class=\"\"><strong>Certain Plastics:<\/strong> Some plastics, while not entirely brittle, can exhibit brittle behavior under certain conditions.
