What type of casting alloy is described as extra hard with good ductility, used for pumps and steam nozzles?

• A. H Monel
• B. K Monel
• C. R Monel
• D. S Monel

Answer: (A)

The type of casting alloy described as extra hard with good ductility, suitable for pumps and steam nozzles, is indeed H Monel. H Monel, which is a nickel-copper alloy, features a specific composition that enhances its hardness, making it particularly resistant to wear and erosion. This quality is integral for applications involving fluid movement, such as pumps, where durability under pressure and the ability to withstand corrosive environments are crucial. The good ductility of H Monel allows it to be shaped and formed without cracking, facilitating its use in various demanding applications, including steam nozzles which require both strength and reliability at high temperatures.
