ASTM B111 C61300 copper pipe hard drawn is a copper-based alloy, commonly known as aluminum bronze. It is primarily composed of copper, aluminum, iron, nickel, and manganese. This combination of elements gives it excellent mechanical properties and corrosion resistance, making it popular in numerous applications.
Chemical Composition of ASTM B111 C61300 Microbore Copper Pipe
The chemical composition of C61300 is as follows:
Copper (Cu): 78-82%
Aluminum (Al): 8-10%
Iron (Fe): 4-6%
Nickel (Ni): 4-6%
Manganese (Mn): 1-2%
Other: <1%
This composition gives C61300 high strength and good wear resistance, while also enhancing its corrosion resistance in marine environments.
Physical Properties of ASTM B111 C61300 Copper Pipe
C61300's physical properties are as follows:
Density: 8.78 g/cm³
Melting Point: 1025°C
Thermal Conductivity: 55 W/mK
C61300 is a non-magnetic material with a low coefficient of thermal expansion, which allows it to maintain dimensional stability in high-temperature environments.
Machinability of ASTM B111 C61300 Copper Pipe
C61300 exhibits excellent processability, including hot working, cold working, machining, and welding. Its specific processing characteristics are as follows:
Hot Working: It can be hot-worked through forging, rolling, or extrusion, making it suitable for the manufacture of complex shaped parts.
Cold Working: Processes such as cold rolling or cold drawing increase the material's strength and hardness, and improve surface finish.
Machining: It can undergo conventional machining processes such as turning, drilling, milling, and grinding, but due to its high copper content, machining requires specialized tools and techniques. Welding: Conventional welding techniques such as gas tungsten arc welding (TIG) and gas metal arc welding (MIG) can be used.
Applications of ASTM B111 C61300 Heat Exchanger Copper Tubing
C61300 is widely used in the manufacture of components requiring high strength and good wear resistance, such as bearings, gears, and valves. Due to its excellent corrosion resistance, it is used in the marine industry for ship propellers and other components exposed to seawater. It is also used in electrical components and heat exchangers, where good electrical and thermal conductivity are required.
