C71500 Copper Nickel Alloy – Composition, Properties And Uses

C71500 Composition

C71500, also known as copper-nickel alloy, is a wrought copper alloy primarily consisting of copper, nickel, and a small amount of iron. The proportion of copper in C71500 varies between 65% and 70%, nickel between 30% and 35%, and iron is present in small quantities of about 0.4%. C71500 also has trace amounts of manganese and silicon. Because of its nickel content, C71500 falls under nickel-copper alloys.

C71500 Physical Properties

C71500 has a density of 8.94 grams per cubic centimetre, slightly higher than pure copper. It has an electrical conductivity of about 3% IACS (International Annealed Copper Standard). Its thermal conductivity is 40 W/m·K, lower than pure copper. C71500 exhibits excellent resistance to stress corrosion cracking and pitting corrosion.

C71500 Mechanical Properties

C71500 has excellent tensile and yield strength. Its tensile strength ranges between 515 and 690 MPa, while its yield strength ranges between 195 and 415 MPa. It has a high elongation of more than 30% and a good hardness of about 120 HV. Its high strength and hardness make C71500 ideal for applications that require heavy loads and strong corrosion resistance.
