AUTRONEX is a -hardened process that is production-proven to significantly reduce consumption, while preventing bleed out in low current density areas. The high efficiency process produces uniform, mirror-bright yellow deposits that exhibit low porosity and a high purity rate, with outstanding wear and corrosion resistance.
