because it has more thermal conductivity . So it conduct more heat in very less time .
Amount of heat trasmited is directly proportional to
1)Area of crossection
2)temperature difference between source and object
3)time taken to the conduct heat
and universally proportional to the 4)length of the object .
Q ∝ A(T2-T1)t/L
Q = K A(T2-T1)t/L
K = QL/A(T2-T1)t
where,
K - thermal conductivity
Q - amount of heat transferred
T2 - temperature of source
T1 - temperature of object
t - Time taken to conduct the heat
L - length of the object
A - area of crossection

Copper is a highly rated for heat conductivity . So the tip of the solder iron is made of copper so that the tip gets heated quickly and the tin is melted more efficiently . Even iron is a good conductor but copper is more economical than iron . So copper is used in the tips
hope you understood
