C12200 copper, also known as alloy 122 deoxidized high-phosphorus (DHP) copper, is one of the many nonferrous metal options we offer here at Sequoia Brass & Copper. As the name suggests, this commercially pure copper has undergone phosphorus deoxidation to enhance its material properties. Specifically, the residual phosphorus the process leaves behind makes C12200 ideal for heavy-forming applications, lending it increased corrosion resistance and compatibility with welding and brazing processes. Also, the material isn’t very electrically conductive or prone to hydrogen embrittlement.

These advantages aren’t found in alternatives like 110 copper, despite the similarities between their mechanical properties, so C12200 copper is a popular choice for many applications. It has common uses throughout residential and industrial projects as well as plumbing and underground systems. Learn more about C12200 (DHP) copper and how it can benefit your applications.

Properties of C12200 (DHP) Copper

Two key factors make C12200 copper an optimal material option: its chemical and mechanical composition properties.

Chemical Composition

What makes C12200 copper unique is its chemical composition of at least 99.9% copper (Cu) and 0.015% to 0.040% phosphorus (P). The copper content of this metal also contains silver (Ag). Together, these elements form reliable copper alloy 122, making it suitable for use across diverse industries.

Mechanical Composition

The mechanical properties of copper alloy 122 include:

  • 49,300 psi ultimate tensile strength
  • 45,000 psi yield tensile strength
  • 0.323 pounds-per-inch density
  • 6,380 ksi shear modulus
  • 17,400 ksi modulus of elasticity
  • 1,880° F to 1,980° F melting point

Applications of C12200 (DHP) Copper

Copper alloy 122 has many potential applications across both the residential and industrial sectors because of its appealing properties. For example, drinking water supply systems might use C12200 copper tubes because of the material’s high resistance to corrosion from water and soil, its heat transfer capabilities, and its sleek interior surface that won’t restrict water flow. It’s also a good option for applications requiring copper tubes rated for varying pressure levels.

Examples of residential applications for C12200 include:

  • Air conditioning systems
  • Refrigerators
  • Plumbing tubes
  • Oil burner tubing
  • Gas lines
  • Heat liners

Alternately, industrial applications for the material include:

  • Gasoline supply systems
  • Hydraulic system lines
  • Oil lines
  • Steam lines
  • Water supply lines
  • Evaporator tubing
  • Heat exchanger tubing
  • Dairy, brewery, and distiller tubing
  • Condensers
