As environmental regulations tighten globally, the HVAC&R industry is rapidly shifting toward natural refrigerants like R-744 to replace high-GWP synthetic refrigerants. However, implementing R-744 systems introduces critical technical challenges, most notably the requirement to withstand significantly higher working pressures while managing production costs and maintaining material reliability. 
This presentation introduces an innovative solution: LS CAT-02, a high-strength, high-corrosion-resistance copper alloy tube engineered specifically for high-efficiency R-744 heat exchangers. Utilizing advanced Oxygen-Free Copper (OFC) with precise Tin (Sn) alloying (0.3–0. 6%) and proprietary planetary rolling technology, this copper alloy achieves a tensile strength excee ...
