Abstract
Engine block cylinder liners are formed from high melting temperature aluminum alloy composites. A cast composite is first formed from a high melting temperature aluminum alloy, e.g. Al-Mn, Al-Cr, Al-Ni, Al-Fe or Al-Cr-Zr, and refractory particles, e.g. alumina. This composite is then extruded into a tubular sleeve. If desired, a long tube may be extruded which is then cut into desired lengths. These new cylinder liners have the following desirable properties: high melting temperature, good strength at the service temperature, higher thermal conductivity than cast iron, good wear resistance and good corrosion resistance.
