* *When the product is for welding applications and so specified by the purchaser, Zn shall be .50% max., Pb .025% max., P .02% max., Sulfur .02% max. and Carbon .05% max.

**Test values are nominal approximations and depend on specimen size and orientation. The values listed above represent reasonable approximations suitable for general engineering use. Due to commercial variations in composition and to manufacturing limitations, they should not be used for specification purposes. See applicable ASTM specification references.

C71500 (70/30) COPPER NICKEL has all the characteristics of C70600 (90/10) copper-nickel, but offers better corrosion resistance in high-velocity seawater. The operating temperature for C71500 (70/30) is also much higher than that of C70600 (90/10), which can assure a long and reliable service life for parts in these conditions. C71500 with its higher nickel content offers added corrosion resistance for critical marine hardware. C71500 Copper Nickel alloy conforms to specifications ASTM B171, ASME SB171, MIL-C-1726F, MIL-C-24679
