:Googling "wood's metal" AND "fusible resistor" produces nothing


Can't say I have ever heard of Wood's Metal being used for fusible resistors in
electrical or electronic equipment. I seem to remember that a major use for
Wood's Metal was as the fusible element in thermal break-circuit fire detectors
used back in the 30's - 50's. They were superseded by much better detectors.
