Gaz leakage exchanger

Hello,
In France we have a lot of problem with the evaporator ( by Profroid)
I want to know what you use of material in commercial and have you the same problem.

Some of the Turkish stuff is very poor, paper thin copper, had one case where return bends kept popping, and the Linde internal pipe work on older cabinets, all you can do is re braze them

Thanks for your answer,
When i have this problem , i have to re braze all exchanger in order to have best result.
The problem is the brazing and the quality of final assembly.
In FRANCE with the most super market , contract is all inclusif , refrigerant , oil, material at 3000/5000€ and the labor .
Yesterday i have a exchanger replacement , outdoor exchanger hitachi air conditioning .
I was angry because i have to repair the new exchanger , the Cooper like a paper.

Sorry for my english , i will learn with everybody
