The present invention relates to implants made of a biodegradable magnesium alloy. The inventive implant is made in total or in parts of a biodegradable magnesium alloy comprising: Y: 0-10.0% by weight Nd: 0-4.5% by weight Gd: 0-9.0% by weight Dy: 0-8.0% by weight Ho: 0-19.0% by weight Er: 0-23.0% by weight Lu: 0-25.0% by weight Tm: 0-21.0% by weight Tb: 0-21.0% by weight Zr: 0.1-1.5% by weight Ca: 0-2.0% by weight Zn: 0-1.5% by weight In: 0-12.0% by weight Sc: 0-15.0% by weight incidental impurities up to a total of 0.3% by weight the balance being magnesium and under the condition that a) a total content of Ho, Er, Lu, Tb and Tm is more than 5.5% by weight; b) a total content of Y, Nd and Gd is more than 2% by weight; and c) a total content of all alloy compounds except magnesium is more than 8.5% by weight.
