Abstract
The invention relates to a composite (1), comprising a Cu—Sn bronze matrix (2) and filaments (3) surrounded by the bronze matrix (2), wherein the filaments (3) contain niobium (═Nb) or a Nb alloy, characterized in that the filaments (3) contain between 0.3% and 20% of volume of copper (═Cu) substructures (4), which are distributed within the Nb or the Nb alloy. The composite can be used to produce a superconducting element with the bronze route which has an improved critical current density.
