Lead Alloy Applications
KANZA’s lead alloys are engineered for critical uses where controlled chemistry and consistent performance directly impact product life and safety.
We support standard and customised alloy grades for battery and cable industries, along with specialised industrial applications.
- Battery grids & plates (Automotive, Tubular, SMF, VRLA)
- Power cable sheathing & sleeves (insulation protection and long service life)
- Chemical equipment parts and lead pipes (corrosion-resistant use-cases)
- Solder and specialty alloy formulations (tin-rich grades as required)
- Industrial components and engineered parts requiring defined mechanical properties
High Quality
Lead Alloy
Quality is managed through defined process controls, melt handling discipline, and batch verification to ensure chemistry remains within the agreed specification limits. Customer-specific impurity thresholds and composition windows can be supported for repeat orders and long-term supply programs.
