C12200 Copper Chemical Properties
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.
C12200 Copper Uses
It is frequently used for components in aerospace engineering applications as well as medical device manufacturing.
Corrosion Resistance
Due to its superior corrosion resistance qualities, Copper C122 is often used in applications where exposure to harsh chemicals or corrosive environments is expected.
Heat Treatment Processes
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.
Machining
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.
Welding
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.
