Over the recent years, the SuperOx team—S-Innovations located in Russia and SuperOx Japan—have earned recognition as world leading manufacturers of 2G HTS wire. In this talk we will present the status of and recent advances in SuperOx 2G HTS wire manufacturing facilities and wire performance.

 We have been incrementally increasing our production capacity, to reflect the increasing demand on wire. In 2020, the overall capacity at SuperOx is 300 km of 12 mm wide wire per year and is being increased further.

 We have expanded the range of SuperOx 2G HTS wire products by adding a newly developed ReBCO composition with a record I_c and J_e performance at low temperature in magnetic field to the original GdBCO composition that is still preferred for applications at 77 K.

 For the GdBCO wire, average I_c at 77 K in self-field is at 600 to 800 A/12 mm, depending on the GdBCO layer thickness, and the I_c standard deviation is 1-3%. The performance of the new ReBCO wire at 77 K is at 450-600 A/12 mm and the I_c standard deviation is 2-5%. The ReBCO wire, however, offers an I_c at 20 K, 20 T of 150-250 A/4 mm and an I_c at 4.2 K, 20 T of 400-500 A/4 mm, which at present are the highest values for commercially available wire to the best of our knowledge. Application of the new ReBCO composition onto a 40-micron-thin substrate in combination with 5 micron per side surround copper stabilisation results in a product with a record high engineering current density of over 1000 A/mm² at 20 K, 20 T and over 2000 A/mm² at 4.2 K, 20 T.

 Another recent development has been the commissioning of laser slitting technology. This technology offers a clean slit edge, free of cracks, in contrast to typical edge damage after mechanical slitting. Laser slitting allows a smooth transition to 3- and 2-mm wide wires of high quality.
