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.
Export Case : Canada – ASTM B88 Large Diameter Custom Copper Tube
We recently completed an export order of C12200 copper tube to Canada. The product was strictly manufactured according to ASTM B88 standard and is a large diameter, non-standard custom tube, used in the main water supply system of a local commercial building.
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
