Conventional powder-in-tube (PIT) method has been the most effectivetechnique for fabricating iron-based superconducting wires and tapes.Tremendous advances have been made during the last few years, especially for122 family pnictide tapes. Here we review some of the most recent andsignificant developments in making high-performance iron-based tapes by theex-situ PIT process, paying particular attention to several fabricationtechniques to realize high-field Jc performance in terms of increase of coredensity and improvement of texture. At 4.2 K, the practical level transport Jcup to 0.12 MA/cm2 in 10 T and 0.1 MA/cm2 in 14 T have been achieved in theK-doped 122/Ag tapes. As for multifilamentary 122 iron-based wires and tapes,the highest Jc values reached so far are 61 kA/cm2 and 35 kA /cm2 at 4.2 K and10 T, respectively for 7- and 19-core Sr-122 tapes. Recently, high JcCu-cladded and stainless steel/Ag double-sheathed 122 tapes have also beenproduced in order to improve either mechanical properties or thermal stability.More importantly, the scalable rolling process has been used for the first timeto demonstrate high Jc values in 122 conductor tapes of 11 m in length.
