Is an alloy a chemical or physical combination?

Answer 1

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.

Answer 2

An alloy is a chemical mixture. The materials aren't just pushed together into a physical mixture, but are bonded at an atomic level in a way as to form an entirely new material. When copper and tin are smelted together to form bronze, the new material binds the copper and tin molecules in a way entirely different than the pure metals. Providing greater strength but less malleability.

Answer 3

An Alloy is a physical combination of two metals like brass is an alloy of copper and tin.

Answer 4

Making an alloy is a physical change. An alloy is a mixture of metals.

Answer 5

Physical change.

Answer 6

This is a chemical change.
