Steel Based Anode Plate

Our Steel based anode plates utilize AISI 304 or AISI 316L stainless steel, manufactured in strict accordance with ASTM A240 standards to ensure consistent composition (chromium, nickel, and molybdenum) and uniform corrosion resistance. They feature ETP (Electrolytic Tough Pitch) pure copper conductive tabs seamlessly welded via laser, resulting in low contact resistance and uniform current distribution across the entire plate. The product supports two operational modes: a sacrificial iron-based anode for wastewater purification via electro-flocculation, and an inert stainless steel anode designed for the regeneration of copper-bearing waste solutions (specifically neutral to weakly alkaline with very low chloride content). Unlike the full range of titanium-based DSA anodes (Ru-Ti, Ir-Ta, PbO₂, Pt-plated, MnO₂) or Pb-Ca-Sn alloy anodes, stainless steel anodes offer the lowest raw material costs and allow for flexible customization-including cutting, punching, and bending-to meet specific dimensional requirements. We offer comprehensive OEM customization, including solid flat plates and perforated flow-directing mesh plates, with a wide range of plate thicknesses and copper tab specifications. With over a decade of experience in R&D and manufacturing, we supply these anodes in bulk to small-scale wastewater treatment plants, micro-scale PCB alkaline waste recovery facilities, and low-capacity hydrometallurgical enterprises worldwide.

This 304/316L steel-based anode plate is a highly economical, dual-function electrode designed for small-scale wastewater electro-coagulation and closed-loop copper recovery from weakly alkaline PCB waste solutions. It is widely used in low-budget wet electrolysis processes, such as the electro-coagulation purification of neutral printing wastewater, electrolytic copper recovery from alkaline micro-etching waste solutions (with trace chloride), and low-corrosivity sulfate-based metal electrowinning. When paired with a stainless steel or pure copper cathode, it forms a complete, low-cost copper recovery system that simultaneously purifies wastewater and produces industrial-grade cathode copper, significantly reducing initial equipment investment for small-scale waste treatment facilities.

Our factory specializes in the production of standard Steel based anode plates; we hold comprehensive production qualifications and operate an independent laboratory for material spectral analysis. All specialized steel anodes for wastewater treatment and copper recovery are manufactured in accordance with ASTM A240 and the HG/T2471-2007 electrode industry standard, with material composition verified by third-party SGS testing. We provide comprehensive stainless steel spectral analysis reports, weld strength test documentation, and full factory certification. Products comply with EU REACH heavy metal regulations and are suitable for procurement by small-scale environmental protection facilities and micro-PCB waste liquid recovery plants worldwide.
