Is this bronze or cooper coin?

It is a bronze coin. It is not made out of copper. The coin is damaged. None of the coins you have shown so far are in any way special. Assuming you do not have a printed coin catalog, you can use the online coin catalog Numista to find this kind of information. The page for this particular coin can for example be found here.

Easy way to find out is the sound.It does not sound like bronze. How did you recognize this is bronze? Any marks on it?The colour? What is it.

All of the 1 penny coins of 1949 of the United Kingdom should have been minted in bronze (see the catalog). I now understand from your message that you suspect your piece may have mistakenly been minted in an incorrect alloy. Please in the future formulate your question clearly.

Coins that have been mistakenly produced on an incorrect blank are extremely rare. The chance of finding such piece is very low. Only with XRF testing you will be able to find out the precise alloy that your piece was made of. That is not something we can help you with on the forum.

Bronze is copper with some white metal (there are several possibilities, tin is most often used) added. The addition of the white metal does not change the density of the metal. The sound of the metal depends on its density. Therefore, sound is not an indicator of whether a coin is copper or bronze.

Copper and bronze can assume a number of colours and shades, depending on heat and chemical treatment. Colour is therefore also not an indicator of whether  a coin is copper or bronze.
