| Cu | 99.6 |
| S | 0.40 |
C14700 Chemical Properties
The chemical properties of Copper C147 vary based on its composition, but generally, it has excellent resistance to oxidation and many acids. It also has excellent electrical conductivity and high strength at elevated temperatures.
C14700 Mechanical Properties
Copper C147 had high strength when cold-worked or heat treated. It also has good ductility and toughness with excellent formability overall. This makes it well-suited for applications that require bending or forming without fracturing or cracking. High-temperature strength is another notable feature of this alloy as it exhibits better tensile strength than other materials at temperatures up to 350°C / 662°F.
| Properties | Metric | Imperial |
|---|---|---|
| Tensile strength | 221 – 393 MPa | 32100 – 57000 psi |
| Yield strength (depending on temper) | 69 – 379 MPa | 10000 – 55000 psi |
| Elongation at break (in 203.2 mm) | 52% | 52% |
| Modulus of elasticity | 117 GPa | 17000 ksi |
| Poisson’s ratio | 0.34 | 0.34 |
| Machinability (UNS C36000 (free-cutting brass) = 100%) | 85% | 85% |
| Shear modulus | 44 GPa | 6380 ksi |
C14700 Physical Properties
Copper C147 has a density of 8 g/cm3, which makes it lighter than most metals and alloys typically used in construction projects or industrial settings. It also has a low melting point at 845°C / 1553°F, which makes it easy to weld if necessary. Its thermal expansion coefficient is 17 x 10-6 K-1, which means that it will expand slightly when heated but not enough to cause significant problems when used in applications where the temperature fluctuates regularly.
| Properties | Metric | Imperial |
|---|---|---|
| Density | 8.94 g/cc | 0.323 lb/in3 |
| Melting point | 1067°C | 1953°F |

C14700 Uses
It is also often used for applications requiring high-temperature strength, such as automotive parts or aerospace components, because it does not lose power even at extreme temperatures up to 350°C / 662°F. This material is often machined into custom parts for various projects due to its good formability.
Corrosion Resistance
Copper C147 is often used in industries such as electrical components due to its excellent corrosion resistance and electrical conductivity properties.
Heat Resistance
Copper C147 exhibits good heat resistance with minimal warping when exposed to temperatures up to 350°C / 662°F.
Heat Treatment
Heat treatment can be done if required but typically only if a specific property such as hardness needs to be achieved because this material already possesses many desirable qualities right out of the box.
Machining
Machining Copper C147 is similar to any other metal. However, special care must be taken due to its softness compared to other metals like steel or aluminium, which have higher melting points than copper c14 7. Additionally, cutting tools should be kept sharp since dull tools can cause premature wear on the cut material.
Welding
Welding copper c14 any number of welding techniques, including TIG, MIG, oxy-acetylene, etc can do seven. However, one must take proper safety precautions since welding generates sparks that could ignite combustible materials near the work area. Furthermore, flux must be added before welding begins to prevent oxidation from occurring during the process.
Conclusion
As you can see, copper c14 7 offers many desirable qualities that make it suitable for a wide range of applications from automotive parts, aerospace components, electrical components, etc., thanks largely due to its impressive corrosion resistance, heat resistance, mechanical properties, physical properties, machinability and weldability. If you’re looking for an affordable metal with great features, then copper c14 seven is what you need!
