Methods for making low resistivity joints

A method of joining wires, the method comprising:

• introducing a magnesium diboride joint material to an end of a first wire and an end of a second wire at a joint area, wherein at least one of the first and second wires comprises superconductive magnesium diboride filaments, and wherein the magnesium diboride joint material comprises a solid joint material having bore holes formed therein;
• stripping the ends of each of the first and second wires to expose an extended portion of the superconductive magnesium diboride filaments of each of the first and second wires;
• inserting the extended portion of the superconductive magnesium diboride filaments of each of the first and second wires into the bore holes;
• and
• affecting the joint area such that the end of the first wire and the end of the second wire are electrically and mechanically coupled through the magnesium diboride joint material.
