Abstract (en)
[origin: DE19532244A1] A process is disclosed for manufacturing thin-walled pipes made of a heat- and wear-resistant aluminium-based material. A billet or tube blank made of a hypereutectic AlSi material is produced, optionally overaged by an annealing process, then extruded into a thick-walled pipe. The thus produced pipe is 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.
