According to Ben Rich (author of the book I am quoting) the Air conditioner fed air into the cockpit at -40 degrees. In spite of that the thing was an oven.
The XB 70 was shirt sleeve comfort at Mach 3.0. Aerodynamic heating increases at the square of the increase in speed. So Mach 4 should be good for furnace brazing in the cockpit....

mach 4.5 = 1 531.305 m / s...............so maybe they could outrun the heat!.................B^)

Ben Rich tells a story about a discussion of the Aurora, the mythical Mach 6 replacement for the Blackbird. He told the guy they were heat warping Titanium with the blackbird. That shut the guy up.
Iridium has the highest melting point. 4800 f I think. But a bit heavy for aircraft.

Yikes. . .I think many share that opinion.

Cockpit temp? Better check that as the dash-board instruments (standard analog) would have warped and stopped functioning.
The jet glowed from the heat but the cockpit was pressurized and air conditioned and the pilot and WSO wore space-suite in case of decompression. . .wouldn't do to lose pressure and be sitting there in nothing but your green nomex flight suite.
Flying above 50,00 feet today requires you wear the space-suite. . .regulations. . .not saying I EVER went above 50K, not saying that, but it is a spectacular view from up there. . .

Above 50,000 feet not an issue as the pressure wave dissipates well before hitting the ground. Sub-sonic flight required over land, not over the ocean. Now, I've flown mach over the water at 5,000 feet, no issues, fun. Flown mach over land, too, and much lower in areas where there is no speed restriction. . .fun to watch the shock-wave ‘puff’ over ponds. . .
