Because of their exceptional resistance to corrosion, particularly in saltwater and brine environments, naval brass rods are used extensively in both marine and industrial applications. Typical applications include fasteners, nuts, bolts, valve stems, propeller shafts, and marine hardware. Additionally, they are used in pump components, condenser plates, heat exchangers, and underwater fittings. Applications needing high strength, durability, and dezincification resistance are best suited for naval brass. It is also used in shipbuilding, industrial machinery, and ornamental architectural elements where durability and visual appeal are essential. It is a reliable material in many demanding industries because of its adaptability and durability.
At least 99.5% pure nickel makes up Nickel Alloy 200 Forgings, with trace amounts of iron (≤0.4%), manganese (≤0.35%), carbon (≤0.15%), and copper (≤0.25%). Excellent electrical and thermal conductivity is offered by this commercially available pure nickel alloy. Its yield strength is between 110 and 280 MPa, its tensile strength is between 340 and 680 MPa, and its elongation is up to 40%. When it comes to critical industrial applications, nickel 200 is extremely reliable due to its remarkable resistance to corrosive environments, particularly alkaline and reducing chemicals, and its ability to maintain its mechanical integrity over a wide temperature range.

After forging Nickel Alloy 200, controlled cooling methods such as air cooling or furnace cooling are typically used to avoid rapid temperature changes and prevent distortion. Gradual cooling helps maintain the material's mechanical properties and prevent cracking.
Post-forging operations for Nickel Alloy 200 include annealing to relieve internal stresses and improve ductility, followed by machining or surface finishing to achieve precise dimensions and surface quality. These processes ensure the alloy's optimal performance and structural integrity.
The ideal temperature range for forging Nickel Alloy 200 is between 1,900°F (1,038°C) and 2,100°F (1,149°C). This range ensures proper malleability and helps achieve the desired mechanical properties during the forging process.
Industries needing high conductivity and corrosion resistance frequently use nickel alloy 200 forgings. Common uses include parts for machinery used to handle caustic alkali, produce synthetic fibre, and process chemicals and foods. Because of their exceptional resistance to acidic and alkaline media, they are also utilised in heat exchangers, battery connectors, marine engineering, aerospace components, and electrical parts. Reactors, pressure vessels, and piping systems are examples of clean processes and reducing environments where nickel 200 is particularly useful. It is appropriate for sensitive instrumentation and the production of electronic hardware due to its purity and non-magnetic nature.
