Abstract: The invention relates to a method for producing a small thin-walled tube for a medical application or for a medical product, in particular for a stent, wherein a blank of an in particular bioresorbable magnesium alloy is deformed to produce a small tube, after which the small tube is used for medical purposes or from which the medical product, such as a stent, can be made.

Abstract: The invention relates to a magnesium-based alloy and a semi-finished product produced therefrom with uniformly small grain size and high cold forming capability. In order to create a fine-grain billet from an ingot, the material of which is highly formable (deep-drawable) at increased temperature and at room temperature and has desirable corrosion properties, according to the invention a magnesium-based alloy (L1, L2) is provided, containing in % by weight zinc (Zn) more than 0.8, but less than 6.2, zirconium (Zr) traces, but less than 1.0, manganese (Mn) more than 0.04, but less than 0.6, calcium (Ca) more than 0.04, but less than 2.0, silicon (Si) traces, but less than 1.0, antimony (Sb) traces, but less than 0.5, silver (Ag) more than 0.1, but less than 2.0, the rest being magnesium and production-related contaminants.
