The Industry Choice
LD Microprecision EFO is more than an EFO. We have done extensive research and collaborated with our Advanced Material Manufacturer to select the optimum material most suitable for the manufacturing of the spark rod. The composite alloy material is called ALC-501* widely used in the aerospace industry.
Not all WB EFOs are manufactured equal.
