Abstract Atmospheric corrosion of aluminium alloy was predic
ted using BP neural network,and relation between training error and predicting e
rror was researched.Artificial Heural network(ANN) model is composed of seven in
put nodes,five hidden layer
nodes and one output node.Correlation coefficient for model is 0.8821,ANN predi
ction result is close to practical data.By sensitivity analysis method,metallurg
ical factor and environmental factor influence for atmospheric corrosion rate of
aluminium alloy was researched.
