Some of our largest competitors use a cheaper alumina-ceramic sleeve to make their liners. Although these liners last a little longer than standard chrome-iron liners, they only last about half as long as zirconia-ceramic liners. Our liners are made from zirconia-ceramic material in order to provide the longest life and best wear performance.
