Abstract (en)

[origin: EP0508858A1] This process consists of the following steps: 1)- specil Zn-Al-Cu alloys, which comprise in percent amounts between 69-79 Zn, 20-30 Al and 1.0-8 Cu, are pre-heated; 2)- then extruded within a temperature range between 176 DEG C and 275 DEG C, at a speed comprised between 1 and 20 meters per minute; 3)- straightening thereafter the extruded shape, and letting same cool at ambient temperature. <IMAGE>
