Phosphor Bronzes(C 50100 - C 52400). Addition of tin and phosphorus to copper produces good resistance to flowing seawater and to most nonoxidizing acids except hydrochloric (HCl). Alloys containing 8 to 10%Snhave high resistance to impingement attack. Phosphor bronzes are much less susceptible t...

Corrosion found in the heat exchanger pipes made of copper was estimated and found to bemicrobially influenced. Laboratory measurements by the use of the same environments were planed.Underground water from the same plant was transferred to laboratory and was used. Bacteria in thetest solution was ...
Stress corrosion refers to the acceleration of metal surface damage due to the combination of corrosion and tensile stress. This phenomenon occurs when applied or internal stress causes atoms to leave the cracks, leading to their sharpening in specific environments. ...
This must be the dumbest thing I have ever done. I used copper sulfate (CuSO4) for an experiment. I first bought copper sulfate in crystalline form and then mixed it in water. After the experiment was done I flashed the copper sulfate down the toilet but some of it was actually absorbed...

The 7xxx-series alloys contain copper and zinc, and these alloys are particularly susceptible to intergranular attack, because of the high galvanic couples between grain bodies and boundaries produced by the heat-treatment. The unstable precipitates formed by the peak-aged (maximum strength) heat-tre...
