Component Specifications

Definition
A specialized metallurgical additive employed in the manufacturing of high-purity copper busbar alloys to eliminate dissolved oxygen from molten metal through chemical reduction reactions, preventing oxide formation and ensuring optimal electrical conductivity and mechanical properties.
Working Principle
Works through redox reactions where deoxidizing elements (typically phosphorus, lithium, or calcium) have higher oxygen affinity than copper, forming stable oxides that separate from the molten alloy as slag or gas.
Materials
Phosphorus-copper master alloys (CuP series), lithium-based compounds, calcium-silicon alloys, or proprietary formulations containing rare earth elements.
Technical Parameters
  • Dosage Rate 0.1-0.5% of melt weight
  • Melting Point 700-900°C
  • Residual Oxygen <10 ppm
  • Phosphorus Content 8-15% in CuP alloys
  • Oxygen Removal Efficiency >95%
Standards
ISO 4312, ASTM B224, DIN 1705

Frequently Asked Questions

Why is deoxidation critical for copper busbars?

Oxygen causes copper oxide formation that reduces electrical conductivity by up to 30% and creates weak points in the microstructure, leading to premature failure in high-current applications.

How does phosphorus deoxidizer work differently from lithium-based agents?

Phosphorus forms P2O5 gas that bubbles out, while lithium creates Li2O slag; phosphorus leaves residual phosphorus that improves fluidity but slightly reduces conductivity, whereas lithium leaves minimal residue.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
