Abstract:
An aluminum-silicon alloy with a hypereutectic amount of silicon in the aluminum alloy for manufacturing liners for internal combustion engines produced by the following steps:spray compacting an aluminum alloy with a hypereutectic amount of silicon in the aluminum alloy melt onto a rotating support pipe such that there is generated directly a thick-walled pipe of a wall thickness of from 6 to 20 mm of the aluminum alloy material with the hypereutectic amount of silicon in the aluminum alloy material, wherein contained primary silicon particles have a size of from about 0.5 to 20 &mgr;m; reducing said thick-walled pipe by a hot-deformation process at temperatures of from 250 to 500Â° C. to a wall thickness of 1.5 to 5 mm.
