Abstract - Very recently, great progress has been made in fabricating high-performance iron-based superconducting wires. At 4.2 K, the transport critical current Jc reached 1.7x104 A/cm2 at 10 T for textured powder-in-tube (PIT)  Sr1-xKxFe2As2 tapes, which approaches the Jc level desired for practical applications. Furthermore, high Jc multi-filamentary 122 type wires were successfully produced.
