ASTM B171 C71500 Copper Nickel 70/30 CW354H CuNi30Mn1FE Plate
We are a professional manufacturer of ASTM B171 C71500 Copper Nickel 70/30 CW354H CuNi30Mn1FE Plate in China.
What is ASTM B171 C71500?
ASTM B171 C71500 (70/30 Copper-Nickel) Plate is a high-strength, corrosion-resistant copper alloy composed of 70% copper and 30% nickel, with small amounts of iron and manganese for enhanced durability. It is widely used in marine, offshore, heat exchangers, desalination plants, and power generation applications due to its superior resistance to seawater corrosion and biofouling.

Why Choose Our ASTM B171 C71500 Plates?
Exceptional Corrosion Resistance – Ideal for seawater applications.
High Strength & Durability – Withstands harsh marine environments.
Biofouling Resistance – Prevents marine organism buildup.
Precision Manufacturing – Meets international standards.
ASTM B171 C71500 Plate/Sheet can be cut into different shape(round disc,square etc),Dimension. ASTM B171 C71500 round discs mainly used as raw material of tube sheets or baffles for pressure vessels, condensers and heat exchangers.
How to fabricate B171 UNS No.C71500 Discs?
UNS No.C71500 Plate and Sheet normally produce in square or rectangle type. If the tube sheet in square or rectangle type, then can cut it direct from the plate or sheet. If the tube sheet is round, then should cut the C71500 plate into discs.
