| Electrical Conductivity | |||
|---|---|---|---|
| The electrical conductivity depends on chemical composition, the lever of cold deformation and the grain size. A high level of deformation as well as a small grain size decrease the conductivity. |
| Corrosion Resistance | |||
|---|---|---|---|
| Cooper is resistant to: natural and industrial atmospheres as well as maritime air, drinking and service water (if the flow rate is not excessive),non oxidizing acids, alkaline solutions and neutral saline solutions. Copper is not resistant to: Ammonia, halogenide, cyanide and hydrogen sulfide solution and atmospheres, oxidizing acids and sea water (especially at high flow rates). |
