Copper weak back ferrules are made of soft high conductivity copper. It is available in many sizes ranging from 16mm2 to 630mm2. It is electro tin or nickel plated.
Copper-Nickel Alloys possess different properties and are used in different applications. It consists of only one phase as the copper nickel binary system exhibits complete solid solubility. It can be hardened only by cold working. The nickel content in these alloys also enables them to retain their strength at elevated temperatures compared to copper alloys without nickel.
Copper/Phosphorus Brazing Alloys are used to braze copper without flux. It is used to braze brass or bronze using a flux. It is recommended to braze high vibrations joints. The copper phosphorus brazing alloys that contain no silver is used on joints that are not subjected to any stress levels or vibration. They are ideal for static joints as found in gas and water pipes fixed in static positions.
