ASTM B111 C70600 Copper-Nickel Alloy Seamless Tube CU-NI Alloy
As a leading manufacturer of stainless steel, duplex steel, and alloy steel pipes in China, we have over 20 years of industry experience and serve customers worldwide with products that consistently earn high praise.
C70600 (C706) and C71500 (C715) copper-nickel alloys offer exceptional corrosion resistance, particularly in marine saltwater environments. These forged copper-nickel alloys, containing 10% or 30% nickel, are enhanced with iron and manganese to maintain superior corrosion performance. Common applications include CuNi fittings, condenser housings, and heat exchanger components.
