Guide to Copper Alloy 122: Properties and Applications

Copper tubes on white background

The addition of phosphorus to copper alloy 122 makes it an excellent option for heavy-forming processes. In fact, this material is easier to braze and weld than 110 copper, even if they are almost identical mechanically. Also, copper alloy 122 has great resistance to corrosion caused by water, weather, and soil. This makes it an outstanding material for underground and plumbing applications. Copper alloy 122 is also used in various household and industrial applications. Read on to learn more.

What Are the Properties of Copper Alloy 122?

Copper alloy 122 is preferred in various sectors due to its valuable properties. We can break them down into two components as follows:

Chemical Composition

The chemical composition of copper alloy 122 contains two elements, copper (Cu) at a minimum of 99.9% and phosphorus (P), which can range from 0.015% to 0.040%. Note that the copper value also includes silver (Ag). The chemical composition of copper alloy 122 makes it a good candidate for diverse applications in several sectors.

Mechanical Information

The mechanical composition of copper alloy 122 can be broken down into various elements, which are highlighted below. Copper alloy 122 has a density of 0.323 lb./in., an ultimate tensile strength of 49,300 psi, and yield tensile strength of 45,000 psi. Also, it has a shear modulus of 6,380 ksi and a modulus of elasticity of about 17,400 ksi. The melting point of copper alloy 122 varies from 1,880° F to 1,980° F.

Other Common Names for Copper Alloy 122

While copper alloy 122 is the correct terminology used in most sectors, there are other names that people use to refer to the same product. Some of the common trade names of copper alloy 122 include:

  • UNS C12200
  • CDA 122
  • DHP Copper
  • DHP Phosphorized
  • High Residual P
  • Phosphorus-Deoxidized Copper
  • C122

Applications of Copper Alloy 122

Due to its high heat transfer qualities, its corrosion-resistance properties, and a smooth interior, it is used as tubing for drinking water since it doesn’t restrict flow. Industries that want to make high, medium, and low-pressure copper tubes use copper alloy 122.

Generally, you’ll find copper alloy 122 in both households and industrial settings. This material is applied as shown below:


  • Plumbing tubes
  • Air conditioners
  • Oil burner tubes
  • Heat liners
  • Refrigerators
  • Gas lines


  • Evaporator tubes
  • Brewery tubes
  • Heat exchanger tubes
  • Distiller tubes
  • Gasoline
  • Oil lines
  • Water lines
  • Dairy tubes
  • Hydraulic lines
  • Steam lines
  • Condensers

C110 Copper Alloy Guide: Properties and Applications

Copper 110, often referred to as C110, is a copper alloy that has been specifically formulated to have superior electrical and thermal conductivity. The ideal application for this metal would be in any type of equipment where electricity must flow from one point to another, such as wiring or electrical components. C110 Copper is also highly formable, meaning it can bend easily without breaking and does not require a lot of force when being formed into a desired shape. Another important aspect of 110 Copper is its corrosion resistance—it will not corrode over time like most other types of metals do when exposed to the elements. This makes C110 an excellent choice for many different indoor and outdoor components.

What Are the Properties of C110 Copper?

Circular and hexagonal copper bars in pileC110 is a form of copper with electrical and thermal conductivity characteristics.

Chemical Composition

The material of choice for the new C110 line is pure copper, which has a 99.9% copper content with the other 0.1% being oxygen.

C110 is a highly conductive copper-based alloy with outstanding electrical and thermal conductivity properties, which is superior to other products available on the market. When heated, it is not brittle or embrittlement-prone like other copper alloys, such as copper alloy 122. C110 also contains the same amount of oxygen that occurs naturally in pure copper (Cu). This makes the alloy ductile, which is beneficial for electronic components that must be free from hazardous impurities and oxide films.

C110 has excellent electrical conductivity, outstanding thermal conductivity, freedom from hydrogen embrittlement, and the potential for cold-working.

Mechanical Information

C110 Copper H02 (Half Hard) Temper

  • Ultimate Tensile Strength: 42,100 psi
  • Yield Strength: 36,300 psi
  • Rockwell Hardness: B40
  • Machinability: 20% 1/2″ or 3/4″ brass rod, also known as free-cutting brass rod (C360)
  • Melting Point: 1,950-1,980° F

Other Common Names for C110 Copper Alloy

Electrolytic Tough Pitch (ETP) copper is another name for copper alloys with a high carbon content, such as C110. They are also more technically referred to as UNS C11000, CDA 110 ETP, C110, and ISO Cu-ETP.

Applications of C110 Copper Alloy

C110 is commonly used in industrial applications where there is a need for ductility (such as in plumbing or roofing) or electrical conductivity (for example, electromagnets, bus bars, electrical motors, and other electrical equipment). It’s most often utilized in the home/residential/ architectural realm for its color (such as a kitchen backsplash or cutting board) or heat transfer qualities (e.g., pots and pans).

In the building and construction industry, C110 Copper has many applications. These typically include: plumbing hardware, wiring, skylight frames, flashing, gutters, and more.

Copper 110 can be welded with precaution, but generally the sort of inert gases required are not recommended for use with copper.
