If I were you, first I’d figure out the analysis on heat conduction of copper sheet. Fourier’s heat conduction equation can be applied in this case, Q/t = kA deltaT / d.
Q = heat energy transferred to the copper sheet
t = duration of heat transfer process
k = thermal conductivity of copper, 385 W/mK
A = transferred surface area of copper sheet
deltaT = temp gradient
d = thickness of copper sheet
Check how much heat energy (in kW or W) is generated by the heater. Now you are ready to calculate how long it will take to heat your copper sheet.
Remember that the melting point of copper is 1085 degrees Celsius. Pick a heater that can control the temperature not to exceed its melting point.

First, copper is a poor choice of materials to heat via resistance or induction. If you really need to heat copper, your best bet is conduction from direct contact with a heating element or convection from a heat gun. Steel that a magnet sticks to is your best bet for induction heating.
Secondly, your question gives no indication of why you need to heat a copper sheet or blade. If for cutting foam or plastic, you might consider a hot wire cutter or a flat blade tip for a soldering gun.
Here’s one way to heat your copper using electrical resistance instead of induction.
