A process is disclosed for manufacturing thin-walled pipes made of a heat- and wear-resistant aluminium-based material. A thick-walled pipe is spray-compacted in a hypereutectic AlSi material, optionally overaged by an annealing process and hot shaped into a thin-walled pipe. This process is particularly suitable to manufacture light metal cylinder liners for internal combustion engines, since the thus manufactured cylinder liners have the required properties regarding wear-resistance, heat-resistance and lowered pollutant emissions.
