                               The below information will help you to crack the interview.
Copper tube specification:

Chemical composition:

DHP(Deoxidized high phosphorous) copper-Phosphorous 0.015 to 0.035%
                                                                        Remainings are copper.
DLP(Deoxidized low phosphorous) copper-Phosphorous 0.05 to 0.012%
                                                                       remainings are copper
