How can I produce 5000 degree Fahrenheit?

Answer 1

The thermite reaction can approach or exceed 5000 degrees fahrenheit.

Be careful if you are going to try this, because you cannot extinguish it once it starts.

Answer 2

Producing temperatures as high as 5000 degrees Fahrenheit generally requires industrial processes, such as using specialized equipment like electric arc furnaces or lasers. Be aware that temperatures this high can pose significant safety hazards and should only be attempted with appropriate training and precautions.
