Can household copper wire be cut by fire?
First of all, we should understand that the melting point of copper is about 1000 degrees centigrade, and the size of copper should also be considered.
The temperature of the flame (different material combustion temperature is not the same, depending on the specific ignition and combustion, even, the same substance produced by the flame will cause the temperature difference because of different parts, such as alcohol lamp flame external temperature is high, and the internal temperature of the burning cigarette can be as high as 800 degrees celsius...... For different objects, because of their different combustion values, the temperature of the burning flame is different, as well as the degree of combustion. Is the oxidation reaction intensity, alcohol lamp and alcohol burner flame temperature difference, general flame due to internal contact with oxygen is not sufficient, not fully oxidized, so the flame temperature is the lowest, which is why the hand pinch out the candle does not feel hot reason. What? Firewood 500 to 600 degrees, if there is fire on the sun, there are thousands of degrees
Have done enameled wire, copper wire only from the side of the flame inserted in the other side of the leak head, the leak out of the head that part will melt, and the formation of a black gray thing. In the middle part of the candle flame, it does not melt. The leaking part burns to the flame and immediately stops melting. If the projection is fast and the length is longer, only a few millimeters closer to the flame will melt.
Finally, it is concluded that the flame temperature of the candle is close to the melting point of copper, and the oxidation rate of copper wire is accelerated at high temperature. The heat released by oxidation leads to the melting point of copper wire and reaches the melting point.
