Because copper and nickel are completely miscible (i.e., they mix thoroughly) in the solid state, forming a complete series of solid solutions, the useful range of alloys is not confined within any definite limits of composition, although certain compositions have come into general use. Additions of 2 to 45 percent nickel to copper provide a series of alloys that are considerably stronger and more resistant to oxidation at high temperatures than is copper. Of these cupronickels, the one containing 30 percent nickel is the most important; it is widely used for steam-condenser tubes. The alloy formed of 20 percent nickel ...(100 of 4534 words)
