Why Do You Prefer LDX 2101 Stainless Steel Cathode Used in Copper Electrowinning?
1. Longer Service Life:
LDX 2101’s corrosion resistance and strength extend service life beyond 15 years.
2. Reducing Your Procurement Cost:
- Material cost of LDX 2101 is lower than 316L.
- Reduced thickness (due to high strength) lowers material weight and shipping costs.
3. Enhanced Strength without Compromising Conductivity:
LDX 2101 offers mechanical strength 2x higher than 316L (yield strength ≥450 MPa), while maintaining equivalent electrical conductivity. This ensures structural integrity in high-load environments without sacrificing electrochemical performance.
4. Superior Corrosion Resistance in Sulfuric Acid Environments:
With a PREN (Pitting Resistance Equivalent Number) of 26-28, LDX 2101 outperforms 304L and matches 316L in resisting sulfuric acid corrosion—critical for electrowinning tanks. Its duplex structure (50% austenite + 50% ferrite) prevents chloride stress corrosion cracking (SCC).
5. High-Grade Surface Finish for Efficient Cathode Copper Sheet Stripping:
The polished surface finish (achieved via cold rolling and descaling) minimizes adhesion, ensuring smooth, efficient cathode copper peeling and reducing downtime.
6. Adaptability to Harsh Operating Conditions:
Ideal for projects in high-humidity, high-chloride, or variable-pH environments due to its:
- Higher hardness (290 HB vs. 217 HB for 316L).
- Excellent erosion and abrasion resistance.
- Cost-effectiveness (lower nickel content reduces price volatility sensitivity).
Manufacturing Process & Quality Assurance
Our production integrates advanced technology and rigorous checks to guarantee performance:
1. Material Selection:
LDX 2101 or 316L is chosen based on client-specific operating conditions (e.g., chloride concentration, pH levels)
2. Design Optimization:
CAD-based engineering collaborates with clients to finalize dimensions and tolerances.
3. Raw Material Sourcing:
LDX 2101 plates, 304 stainless tubes, and ASTM C11000 copper bars/pipes are procured from certified suppliers
4. Precision Machining:
Laser cutting of LDX 2101 plates to exact dimensions.
Conductive beam fabrication: Copper-stainless steel composite bars are metallurgically bonded via patented technology, ensuring seamless integration and minimal electrical resistance.
5. Welding:
Fully automated robotic laser welding (double-sided full penetration) joins the plate and conductive beam, validated via NDT (e.g., ultrasonic testing) for defect-free seams.
6. Edge Strip Installation:
PPO edge strips are mounted to prevent short-circuiting.
7. Dimensional Inspection:
Flatness (≤±2 mm/m²), verticality, and suspension alignment are verified.
8. Packaging:
Plates are vertically mounted on steel frames to prevent deformation during transit.
