pH value

The water cooling cartridge partially consists of a copper and nickel alloy, to which the following applies:

  •  Corrosion issues when pH value is < 6
  • The following applies to alkaline water:
  • → Corrosion problems when water hardness is < 6°dH.
  • Lower values can lead to corrosion due to free carbon dioxide.
  • The following table describes the classification of the water quality based on the pH value:

pH value

Water quality

4.5

Strongly acidic

4.5 – 6.0

Acidic

6.0 – 6.8

Slightly acidic

7.0

Neutral

7.2 – 7.7

Slightly alkaline

7.7 – 8.2

Alkaline

8.2

Strongly alkaline
