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 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 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.


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!
