As a company that manufactures wire for numerous industries, having a range of alloys that are specifically catered to prevent corrosion is crucial to ensure our customers can find exactly what they need. First, it’s important to understand why metals can corrode. Â
Metals can corrode for numerous reasons, especially in harsh conditions. Examples of typical metal corrosions include metal reacting with a substance like oxygen or hydrogen, or a metal being placed under too much stress causing the material to crack. Â
At CWI we have the corrosion resistant metal alloys you need to ensure long-lasting performance even in the harshest of conditions. Our research and years of manufacturing experience promise materials that can withstand corrosive environments. Â
Today’s Challenges
As industries around the world push for higher and higher levels of performance in their materials, metallurgists continue to develop new and exciting alloys to meet today’s challenges.
