Excellent Corrosion-Resistant Wire Materials: Zinc-Aluminum Alloy Wire and Pure Zinc Wire
Zinc-aluminum alloy wire typically refers to an Zn85Al15 alloy wire .
Pure zinc wire contains 99.995% zinc.
Zinc wire and zinc-aluminum alloy wire are excellent choices for corrosion protection in atmospheric and marine environments.
Applied via arc spray or flame spray, zinc and zinc-aluminum alloy wire coatings act as sacrificial anodes, providing electrochemical protection for iron or steel substrates. This spraying process is more effective and durable than hot-dip galvanizing.
Also, arc sprayed zinc and zinc-aluminum alloy wire coatings are commonly used in the electronics industry for electromagnetic interference (EMI) and radio frequency (RF) shielding, or as conductive coatings for capacitors.
Zinc-aluminum alloy wire coatings offer superior corrosion protection compared to pure zinc wire coatings. Unlike zinc coatings, zinc-aluminum alloy wire can be used in slightly acidic environments, including industrial environments with sulfur dioxide.
Additionally, zinc-aluminum alloy wire coatings can be used in water at higher operating temperatures, have better bond strength on properly prepared surfaces, and offer better coating corrosion resistance than pure zinc wire coatings.
