Abstract (en)
[origin: CA2942426A1] The invention relates to extruded products suitable for turning, made from aluminium alloy with a composition (in weight %) of: 0.4 - 0.8 Si; 0.8 - 1.2 Mg; 0.20 - 0.4 Cu; 0.05 - 0.4 Fe; Mn = 0.10; Ti < 0.15; Cr = 0.10; Bi = 0.8; Pb = 0.4; other elements < 0.05 each and < 0,15 remainder being aluminium, characterised in that the granular structure thereof is essentially recrystallised. The invention also relates to the method for the production of said products. The invention further relates to anodised turned mechanical parts obtained from extruded products according to the invention and to the production method thereof. The products of the invention are particularly suitable for the production of brake pistons and gearbox elements.
