Monel 500 Hexagon Rods
The hexagon shape of these rods is particularly advantageous for manufacturing fasteners, bolts, nuts, shafts, and valve components, as the flats facilitate machining, wrenching, and assembly operations. This shape also allows for easier handling and more efficient utilization of material during production compared to round rods..
Mechanically, Monel 500 hexagon rods exhibit a tensile strength ranging from approximately 930 to 1100 MPa, with a yield strength of around 690 MPa in the aged condition. The elongation typically ranges between 15–25%, and hardness in the Rockwell C scale can reach 30–40 HRC. Its density is about 8.44 g/cm³, and it remains non-magnetic, making it suitable for applications in sensitive environments..
The chemical composition of Monel 500 typically includes 63–70% nickel, 27–33% copper, 2.3–3.15% aluminum, and 0.35–0.85% titanium, with trace amounts of iron, manganese, silicon, carbon, and sulfur. This precise composition allows the alloy to achieve superior strength and toughness compared to standard Monel 400, while retaining excellent resistance to seawater, acids, and alkaline solutions.
Monel 500 (K‑500 / UNS N05500) hexagon rods are high-performance nickel-copper alloys designed for applications requiring both exceptional corrosion resistance and high mechanical strength. The alloy is age-hardenable due to the addition of aluminum and titanium, which enhances its hardness and tensile strength while maintaining excellent ductility, non-magnetic properties, and resistance to a wide range of corrosive environments.
