Smaller-diameter copper tubes strengthened with low percentages of alloying elements
Withstand highter pressures of CO2 (R744)
High strength thermal conductivity
Minimise wall thickness and materials
Description
Low-alloyed copper contains small percentages of elements such as nickel, tin, iron or other metals. These alloying elements significantly strengthen the copper tubes. They accomplish this by reducing the grain size in the microstructure thus increasing the yield strength. Tube suppliers report increases in the burst pressure of 20 percent to 50 percent compared to C12200 for the same wall thickness.
