FIELD: medicine.
SUBSTANCE: group of inventions relates to medicine. Manufacturing curved surgical needles from tungsten alloy includes stage of heating blanks for manufacturing needles from tungsten alloy or surgical needles from tungsten alloy. Heating is performed for certain temperature which is lower than temperature of used alloy re-crystallisation.
EFFECT: resulting surgical needles from tungsten alloy possess desirable combination of rigidity, strength, ductility and colour of surface.
