Which temperature is associated with a brazing flame described as producing a sharp flame?

Explanation:
In brazing, a sharp flame describes a hot, focused heat zone where the inner cone is well-defined and the heat is concentrated on the joint. That concentrated, high-temperature flame is typically around 5400°F, which is hot enough to heat the joint quickly without excessive diffusion of heat to surrounding areas. The cooler temperatures listed (3200°F and 4200°F) wouldn't be described as a sharp, intense brazing flame, and while flames can reach higher temperatures, 6000°F is hotter than the commonly referenced sharp flame description and not the standard heat level associated with that term.
