Zinc Alloy Coil & Strip

IRG offers a range of zinc alloys primarily for fuse element applications and corrosion resistant electrical contact applications.   Most people realize that zinc is the element material of choice for electrical fuses due to its excellent electrical conductivity and its relatively low melting temperature.  Zinc has the electrical conductivity equal to 70/30 brass.

In addition, zinc offers excellent formability.  It is also easily soldered to itself and other materials.   It can be readily joined as well by resistance welding and other assembly methods.   Zinc is non-magnetic.   Also, zinc is resistant to weather and atmospheric corrosion making it well known for galvanizing steel.

Lastly, solid zinc strip results in cost savings of 25 - 45% over brass and copper alloys.   It will yield 18 - 25% more parts per pound.   If you have an application that may be a candidate for zinc strip, please contact IRG for a review of your requirements.
