C12200 copper composition is a type of copper alloy that contains around 99.9% pure copper, along with small amounts of lead and phosphorus to improve its machinability. This composition makes it an ideal material for many different applications, including plumbing, electrical wiring, and architectural design. Its high conductivity and corrosion resistance make it a popular choice in various industries. The C12200 copper composition also has excellent thermal and electrical conductivity, making it ideal for conductors and heat exchangers.
The addition of cobalt to pure copper creates an alloy that has higher levels of wear resistance than pure copper alloys. Additionally, it features superior hot-shortness and high hardness at elevated temperatures when compared to other copper alloys. Copper C122 is a durable and corrosion-resistant alloy which features its unique combination of mechanical properties, wear resistance, and low coefficient of friction. It is an alloy composed of copper, nickel, chromium, and molybdenum, which gives it superior tensile strength when compared to other copper alloys. Furthermore, its solderability is excellent in both acidic and alkaline environments, making it the ideal choice for many applications. Copper C122 provides exceptional repeatability and accuracy in machining while still possessing impact toughness due to its ability to work hard without fail. These properties make it a preferred alloy for numerous industries that highly value performance and reliability.
Copper C122 is a versatile alloy exhibiting excellent mechanical properties that make it ideal for many industrial applications. Its thermal expansion coefficient is well balanced, and its strength-to-weight ratio is high enough to make it very stable in even extreme temperatures. Its low coefficient of friction makes copper C122 an effective material for tribological components, such as bearings, bushings and gears. Also, copper C122 has excellent wear characteristics thanks to its work-hardening abilities, making it well-suited for use in abrasion-resistant machine parts. In addition, copper C122 boasts superior corrosion resistance and outstanding electrical conductivity, making it suitable for situations where a balance between both electrical connections and mechanical performance is needed. Copper C122 truly lives up to its reputation as an essential industrial material.
Copper C122 is a ductile metal with excellent weldability characteristics. It has a melting point range between 1730-1790°F (945-980°C). Its tensile strength ranges from 60-90 ksi (414-621 MPa) depending on the heat treatment processes used during fabrication.
It is frequently used for components in aerospace engineering applications as well as medical device manufacturing.
Due to its superior corrosion resistance qualities, Copper C122 is often used in applications where exposure to harsh chemicals or corrosive environments is expected.
The most common heat treatment applied to this alloy are annealing and solution treating/precipitation hardening (ST/PH). Annealing involves heating the metal above its recrystallization temperature before slowly cooling it down in order to increase both its ductility and formability characteristics. Solution treating/precipitation hardening increases the material's hardness by creating precipitates within the metal which strengthens it against wear or tear over time.
Due to its high thermal conductivity (400 W/mK), machining with Copper C122 can be difficult due to rapid tool wear caused by excess heat buildup during cutting operations.
When welding this material, it should be preheated prior to welding in order to prevent cracking during cooling due to rapid thermal expansion differences between base materials and filler metals used during welding operations.
