High-Phosphorus Deoxidized Copper ASTM B111 DHPC12200 is an oxygen-free copper material produced through a phosphorus deoxidation process. It exhibits excellent electrical and thermal conductivity, as well as corrosion resistance, and is widely used in the electronics, electrical, and machinery manufacturing industries.
Material Introduction
DHPC12200 is made from electrolytic copper. A trace amount of phosphorus (0.015%-0.040%) is added for deoxidation, significantly reducing the oxygen content (≤0.003%), preventing hydrogen embrittlement and improving the material's ductility and weldability.
Production Process
Melting: Electrolytic copper is smelted with a phosphorus-copper master alloy to control the phosphorus content.
Continuous Casting: Hot-rolled into billets or directly drawn into shapes.
Cold Working: Adjusting hardness and strength through rolling or drawing.
Material Characteristics
High Electrical and Thermal Conductivity: Electrical conductivity exceeds 98% IACS.
Corrosion Resistance: Phosphorus inhibits oxidation, extending service life.
Easy Processing: The soft state is suitable for deep drawing, while the hard state is suitable for high-strength components.
Main Applications
Electronics Industry: Circuit board leads, relay components.
Power Equipment: Transformer windings, conductive terminals.
Mechanical Manufacturing: Vacuum components, heat exchanger piping.
DHPC12200's comprehensive performance makes it an ideal choice for precision industries.
