Copper has a metallic lustre, and a reddish-orange colour when its surface is freshly exposed. It is soft, and a good conductor of both heat and electricity.

Because flammability involve burning, a chemical reaction of oxidation.
Color, smell, taste ...
Flammability is a chemical property because the matter undergoes a chemical change (change in the make-up molecules) when it is burned.

Yes, it is. You aren't altering the chemical composition at all - it's still copper - you are merely changing its shape.
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.

Cutting a piece of copper in half is a physical change because it only alters the physical appearance of the copper without changing its chemical composition.
It is a physical change since...well...no other chemicals are involved...copper is still copper.
Copper has both chemical and physical properties. Chemical properties refer to how copper reacts with other substances, while physical properties refer to characteristics like its color, density, and conductivity.
