ASTM B111 C44400 Copper Pipe in AC Material Overview
ASTM B111 C44400 copper tube soldering is a leaded, free-cutting, phosphorus-deoxidized copper alloy, a copper material in the ASTM B series of standards. It offers excellent machinability and corrosion resistance. The addition of lead significantly improves cutting efficiency, while the deoxidizing effect of phosphorus improves the material's density, making it a widely used raw material for copper tubes and copper plates in industry.
ASTM B111 C44400 Copper Water Pipe Chemical Composition
C44400's main components include:
Copper (Cu): ≥99.9%; acts as a matrix, providing electrical and thermal conductivity, and corrosion resistance;
Lead (Pb): 0.8%-1.2%; improves cutting performance and reduces tool wear;
Phosphorus (P): 0.015%-0.04%; acts as a deoxidizer and enhances fatigue resistance. Trace impurities such as iron and zinc must be strictly controlled to ensure material purity.
