1. Introduction: The Critical Role of Stainless Steel Cathodes
Stainless steel cathodes are key equipment in the production of electrowinning copper, specifically used for depositing cathode copper. Their performance hinges on three core attributes: surface finish quality, blade flatness, and vertical precision. In this article, we break down why these specifications matter and how our cathodes meet rigorous industrial demands.
2. Surface Finish Grade 2B: The Gold Standard for Durability
What is Grade 2B Finish?
- A cold-rolled, annealed surface with a smooth, reflective appearance.
- Resists corrosion and minimizes contamination in harsh environments.
Why It Matters for Cathodes:
- Reduced Friction: Ensures uniform deposition in electrowining.
- Longevity: Withstands acidic/alkaline solutions without pitting.
- Consistency: Meets ISO 9444 standards for industrial reliability.
- Easy to Strip: Mirror-like smooth surface of the blade is easy to strip the cathode copper sheet.

3. Blade Flatness Tolerance: Less Than and Equal to (≤) 2mm/m
The Science of Flatness:
- Flatness deviations >2mm/m can cause uneven current distribution, influencing deposit effect.
- Too much deviation of flatness will cause the cathode copper to not adhere firmly during deposition and fall off the cathode prematurely.
Industry Applications:
- Electrowinning: Ensures uniform metal deposition on the cathode surface.
- Chemical Processing: Maintains smooth surface integrity to prevent contamination.

4. Verticality (Drape) of the Blade: Stability in Action
Why Verticality Matters:
- A blade deviating from true verticality can lead to uneven wear, affecting the quality and lifespan of the cathode.
- Our cathodes are engineered with ± 5.5 mm (Either Side – measured at any location across the bottom width of blade) drape tolerance to ensure:
- Structural Integrity: Prevents deformation under load, ensuring long-lasting performance.
- Process Accuracy: Maintains precise alignment in continuous production, improving overall operational efficiency.
