A coaxial cable may include an inner conductor, an outer conductor, and a dielectric material layer therebetween. The inner conductor may include a tubular bimetallic layer having a pair of opposing longitudinal edges at a longitudinal seam. The tubular bimetallic layer may include an inner metal layer and an outer metal layer bonded thereto with the inner metal layer having a lower melting point than the outer layer. At least one of the opposing longitudinal edges of the tubular bimetallic layer may be at least partially bevelled. In addition, the longitudinal seam may include a welded joint between at least portions of the opposing longitudinal edges.
