Corrosion Resistance - an overview | ScienceDirect Topics

The corrosion resistance of heat treatable AlMgSi-type alloys, which normally have the best corrosion resistance in the hot-aged state, on the other hand, is adversely affected by the heat of welding, and the same applies for AlZnMg alloys. However, heat treatment after welding restores the material to the best corrosion resistance state.

High Electrical Resistance - The Online Hub for Corrosion ...

High electrical resistance is the opposition to current flow within a circuit. Electrical resistance explains the relationship between voltage and current. A high electrical resistance of an electrical conductor is the opposition to the flow of an electric current through that conductor; the inverse measure is known as electrical conductance.
