DOMADIA™ CuNi30Mn1Fe Alloy UNS C71500: Built to Brave the Impossible
The Alloy Designed to Handle the Toughest Challenges
Imagine a material created to survive the harshest oceans, the hottest industrial plants, and the toughest weather conditions. DOMADIA™ CuNi30Mn1Fe is that material — a Copper-Nickel alloy crafted to deliver outstanding performance where others fail. If you need strength, reliability, and endurance, you’re in the right place. Let’s dive into the 4 W’s and discover why this alloy stands apart!
What is DOMADIA™ CuNi30Mn1Fe?
DOMADIA™ CuNi30Mn1Fe is a superhero in the metal world — a Copper-Nickel-Manganese-Iron alloy designed for superior corrosion resistance, durability, and performance. It proudly meets the standards of EN 1652 and ASTM B122 and is tagged under EN CW 354H and UNS C71500. Crafted for those who build the future, this material knows no limits.
🔍 Are copper and nickel the same? No — copper and nickel are two distinct metals. However, when combined, they form powerful alloys like DOMADIA™ CuNi30Mn1Fe, where their complementary strengths create enhanced corrosion resistance and mechanical integrity.
