The refrigerating circuit presenrs a lot of points in which it is necessary brazing material support.
traditional silver based alloys can be use for Fe/Fe, Fe/Cu (usually T90S a 40% Ag with Sn ) and Copper Phosphorous for Cu/Cu joints ( CuP with Ag such as FH45, FH46 or FH35). Otherwise it is possible to use a brass based alloy such as the SM23MR for all the circuit with flux in the flame or with ECOFLUX® liquid flux
