It is backed with high quality low carbon steel, with tin-lead-bronze alloy (CuSn10Pb10) sintered on its surface. To decrease abrasion, the surface of alloy is machined with diamond shape sockets in which particular solid lubricant is filled. When necessary, the steel back can be plated with an anti-erosive coating. It's fit for applications in higher temperature and the water or other conditions that is impossible or difficult to add oil.
