Other Designations


Copper alloys that are free from oxygen content are best suited for applications that require high ductility and conductivity.

This alloy is referred to as remelted high conductivity (RHC) copper ally. It is used in the form of a brazing filler metal. It exhibits very good corrosion resistance in the presence of atmospheric corroding agents and brackish or sea water. However, exposure to oxidizing environments or oxidizing acids or moist halogens must be avoided.

This datasheet will elaborate on the chemical composition and properties of copper UNS C11010 alloy.
