I'm not sure of a number, but I can say that I used it to patch holes in an exhaust manifold cover (also used as heater) for a VW bug...and it all burned off and really smoked up the car.

 

The Rx-7 guys use it in their engines.. So 1800 degrees F isnt hurting it! They last too!

 

500 degrees

 

it says it on jbweld site

How do you figure that their engines are getting 1800 degrees?

Aluminum melts at 1218 degrees F

or grape fruit

 

1800 is what I heard from an engine rebuilder.. Thats the temp @ exit of exhaust since its a turbo chrager.. So lets just say its getting fucckin hot in the combustion chamber!

 

Q: How much heat can J-B Weld withstand?

A: J-B Weld (Part # 8265-S, 8265, and 8280) can withstand a constant temperature of 500 degrees F. The maximum temperature threshold is approximately 600 degrees F for a short term (10 minutes).
