LONG COMPOSITE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a conductive material that is lightweight and has high strength. SOLUTION: This long composite is formed by compounding at least boron and magnesium. The long composite is formed by passing a linear body containing at least boron through molten metal of magnesium or a magnesium alloy. The composite contains MgB2 . According to the invention, a conductor being lightweight and having high hardness is obtained as a coil with required shape.
