Abstract (en)

[origin: US6086819A] PCT No. PCT/EP96/03778 Sec. 371 Date Feb. 27, 1998 Sec. 102(e) Date Feb. 27, 1998 PCT Filed Aug. 28, 1996 PCT Pub. No. WO97/09457 PCT Pub. Date Mar. 13, 1997A 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 or round bar. The thus obtained preform is severed and extruded 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.
