Abstract: The invention relates to a continuously cast bolt made of an aluminum-based alloy for an extruded profile that has a yield strength of greater than 260 MPa, preferably greater than 280 MPa, in particular greater than 300 MPa. According to the invention, it is provided that the aluminum-based alloy contains, in percentage by weight, greater than 0.0% to 0.40% iron, 0.40% to 1.2% magnesium, 0.60% to 1.1% silicon, greater than 0.0% to 0.35% copper, greater than 0.0% to 0.35% chromium, 0.40% to 0.95% manganese, up to 0.2% zinc, optionally 0.005% to 0.15% titanium and/or 0.005% to 0.15% titanium diboride, and a remainder of aluminum and production-related impurities, wherein a secondary dendrite arm spacing of the microstructure is less than 100 ?m. The invention furthermore relates to an extruded profile created from a continuously cast bolt of this type, and to a method for producing an extruded profile.

Abstract: The invention relates to a magnesium alloy containing (in % by weight) more than 0.0 to 7.0% zinc, optionally more than 0.0 to 1.0% zirconium, optionally more than 0.0 to 1.0% calcium, optionally more than 0.0 to 1.0% manganese, optionally more than 0.0 to 0.5% silicon, optionally more than 0.0 to 1.0% silver, a max. up to 0.5% aluminum and at least one element selected from the group comprising more than 0.05 to 0.6% yttrium, more than 0.05 to 4.0% ytterbium, more than 0.05 to 4.0% gadolinium, with the residue being magnesium and impurities due to production. The invention also relates to a use of a magnesium alloy of this type and an implant therefrom and a method for producing a body of a magnesium alloy according to the invention.
