Copper C122 Fasteners are made from UNS C12200 deoxidized high-phosphorus copper (DHP copper) and are valued for their good corrosion resistance, thermal conductivity, electrical conductivity, and forming characteristics. Also identified as CDA 122 Copper, Cu-DHP, CW024A, and ISO Cu-DHP, this copper grade is widely used where reliable fastening performance and resistance to hydrogen embrittlement are important.
We manufacture and supply Copper C122 Bolts, Screws, Nuts, Washers, Studs, Threaded Rods, U-Bolts, and custom fasteners for industrial applications. Our UNS C12200 DHP Copper Bolts can be supplied in different dimensions, thread forms, finishes, and configurations according to customer drawings and applicable standards.
For buyers looking for a Copper C122 Fasteners Manufacturer, UNS C12200 DHP Copper Bolts Supplier in India, or Copper C122 Fasteners Exporter, we provide material documentation and customized supply options for domestic and international requirements.
What are Copper C122 Fasteners?
Copper C122 Fasteners are threaded and non-threaded fastening components manufactured from UNS C12200 deoxidized high-phosphorus copper. They offer good corrosion resistance, thermal and electrical conductivity, and excellent hot-working and forming characteristics. Copper C122 fasteners are commonly supplied as bolts, screws, nuts, washers, studs, threaded rods, and U-bolts for plumbing, heat-transfer, electrical, HVAC, and industrial applications.

What is Copper C122 / UNS C12200?
UNS C12200 is a commercially important deoxidized copper grade containing phosphorus as the deoxidizing element. It is commonly known as DHP copper, or deoxidized high-phosphorus copper. In European material identification, it is associated with Cu-DHP and CW024A.
The addition of phosphorus reduces the oxygen content of copper and makes the alloy suitable for applications involving welding, brazing, and forming. C12200 also retains many of the useful characteristics associated with copper, including good thermal conductivity and corrosion resistance.
Because of this combination of properties, CDA 122 Copper Bolts and Screws are used in systems where the fastener needs to withstand moisture, heat-transfer environments, or contact with copper-based components.
