ASTM B111 C44300 O61 Copper Alloy Steel Heat Exchanger Tube , Condensers
ASTM B111 refers to the standard specification for Seamless Copper and Copper-Alloy Condenser and Heat Exchanger Tubes. This standard specifies the materials, mechanical properties, and dimensions of the tubes used in heat exchange systems, ensuring quality, performance, and uniformity.
C44300 is a specific copper alloy within the broader family of copper alloys. The "C" in the designation stands for copper, and the number "443" designates the specific alloy. In this case, C44300 is a copper-silicon alloy, also known as 90-10 copper-silicon alloy
O61 refers to the tempering or heat treatment condition of the alloy. In this case, O61 is an annealed condition of the copper alloy, meaning the material has been heat-treated to relieve internal stresses, soften the metal, and improve its formability. The "O" typically refers to an annealed or softened state, and the "61" is a code for a specific form or temper under this annealed condition.
