Making an alloy is a physical change. An alloy is a mixture of metals.
It is a physical change as an alloy is a solid solution made from various metals. As you can still separate these different metals after the alloy is made it is a physical change and not a chemical change.
This is a "twilight zone" type answer because it could be both. For example, in low-carbon steel, there are quasi-compound types compounds that are formed; this is why early blacksmithing was such an art to obtain the right amount of carbon in iron and work it in correctly.
By melting the two metals and putting them together, you are creating an alloy, a homogenous mixture. The process does not change any atoms, so it is not a chemical reaction, but a physical change.

An alloy is a mixture of two or more elements, with at least one being a metal. Chemical properties of an alloy depend on the elements present and their proportions, affecting properties like corrosion resistance and reactivity. Physical properties include hardness, conductivity, and melting point, which also vary based on the alloy composition.
Changing the proportions of substances in an alloy will change the physical properties of that alloy. The differing substances will change the metallic structure of the crystals of the metal alloy, and this alters the ductility, durability, hardness, tensile strength, toughness and other characteristics we assess are regards alloys.
An alloy hasn't a chemical equation !The concentation of chromium in the alloy is variaible depending on the type of alloy.
No, adding copper to gold to create jewelry is not a chemical change; it is a physical change. This process involves alloying, where metals are mixed to form a new material with different properties, but the original metals retain their chemical identities. The resulting alloy, such as rose gold or white gold, can be reshaped and manipulated, but no new substances are formed during this process.

no, it is an alloy.
A copper-gold alloy hasn't chemical bondings.
It melts the metal, but this does not change the alloy. Heating may mix metals into an alloy. Structurally, heating the alloy will improve strength.
