Brass is composed of copper and zinc,Tin Bronze and its characteristics... rmw- xC↓ is composed of copper, tin and phosphorus (P). We have learned the chemical method,Tin Bronze and everyone knows that phosphorus (P) is a red element, so the appearance characteristic of phosphor bronze is red. Therefore,Tin Bronze we can use its characteristics to identify:
The technical products we use (such as the charging data cable used in mobile phones to transmit the signal and current of the conductor metal material of the connector terminal to identify whether it is brass or phosphor bronze),Tin Bronze because the conductor metal in the mobile phone has been electroplated surface treatment.
At this time,Tin Bronze we dissect the charger data line to dissect the metal parts of the connector terminal that transmits signals or current,Tin Bronze and then use a blade to scrape off the metal surface of the terminal.
If it is yellow after removing the plating,Tin Bronze it is brass, and if it is red,Tin Bronze it is phosphor bronze. Since the connector terminal structure of the mobile phone charger data line is very small,Tin Bronze if it is not visible to the naked eye, you can use the mobile phone camera function to zoom in and look at it,Tin Bronze and if it is clear, place it on the microscope.
