Cored wire is a low-carbon steel sheath filled with alloy or metal powder, fed into the ladle or mould by a wire feeder so that the reagent reacts below the slag layer instead of burning at the surface.
Bright Alloys supplies Ø9 mm and Ø13 mm cored wire with CaSi, CaFe, pure calcium, FeSiMg, inoculant and carbon cores, with core weight and sheath thickness matched to your feeding equipment.
CaSi and CaFe wires deliver calcium deep into the ladle for desulfurization and inclusion modification in linepipe, AHSS and bearing steel grades.
FeSiMg and inoculant wires give a controlled, repeatable magnesium recovery, replacing tundish-cover and in-mould methods on high-volume casting lines.
Carbon and alloy wires adjust carbon and microalloy content with the reagent released under the slag rather than lost to oxidation at the bath surface.
Our metallurgical experts provide application guidance and technical support for optimal alloy selection and usage.
