What is the Melting Point and Conductivity of Zinc Wire?
Zinc wire has a relatively low melting point of 419.5°C, which makes it easy to melt, atomize, and apply in industrial processes such as thermal spraying and galvanizing. Its moderate electrical conductivity (~16.6 MS/m) allows stable arc formation in spray systems, ensuring consistent coating quality and efficient energy transfer during operation.
These two properties together make zinc wire one of the most efficient materials for corrosion protection and metallurgical applications.

Why Do Melting Point and Conductivity Matter in Zinc Wire?
Why is the Low Melting Point Important?
Zinc wire melts at only 419.5°C, which means:
- fast melting in arc spray systems
- low energy consumption
- stable atomization during coating
- improved deposition efficiency
This makes it ideal for continuous industrial coating processes.
How Does Electrical Conductivity Affect Performance?
Moderate conductivity ensures:
- stable arc ignition in spray equipment
- consistent wire melting rate
- uniform coating deposition
If conductivity is too low or inconsistent, arc instability may occur.
Why Is Thermal Conductivity Important?
Thermal conductivity helps zinc wire:
- distribute heat evenly during melting
- avoid local overheating
- maintain stable spray performance
