Nickel 405 Nickel 405 Supplier With a high sulfur count and similar corrosion resistance to Nickel 400, 405 provides easier machinability while still delivering a strong and long-term type of metal for you to work with! We are a trusted 405 supplier. As is the case with all Stainless Shapes, you pick the metal and have it sent to you in no time at all. Features of Nickel 405 Chemical Composition – It is predominately 63% Nickel and anywhere from 28-34% copper. This guarantees the most amount of chemical and corrosion resistance from the nickel while also maintaining the brute hardness that comes with using a majorly copper metal. Trace elements of Carbon, Sulfur, Silicon, Iron, and Manganese. This creates a formidable blended metal that is durable as well as very machinable for the needs of your job. Corrosion Resistance – It exhibits many of the same corrosion resistance and physical properties as Nickel 400; however, the range of mechanical properties does not completely mirror those of Nickel 400. This grade is used primarily as automatic screw machine stock where corrosion resistance and toughness are required. Machinability – The higher sulfur content of the 405 Allow allows for enhanced machinability, making this alloy the free machining grade of Nickel 400. Similar to Nickel 400, 405 is a high-Nickel alloy consisting of at least 63% Nickel alloyed with Copper, some Iron, and other trace elements. This material is valued by many industries for its combination of high strength and corrosion resistance over a wide range of conditions and temperatures. Not Sure What You’re Looking For?

Call - 800-748-9811 Frequently Asked Questions What is Monel 405? + Monel 405 (UNS N04405) is the free-machining version of Monel 400, with sulfur added (0.025-0.060%) to improve machinability by promoting chip breaking. Its corrosion resistance, mechanical properties, and general characteristics are similar to Monel 400, with the exception of slightly reduced weldability due to the sulfur addition. What are the disadvantages of Monel? + Monel 405 is the free-machining variant of Monel 400. It is used specifically when Monel 400s corrosion resistance and mechanical properties are required in applications demanding high-volume automatic screw machine or CNC lathe production. The sulfur addition significantly reduces tool wear and improves chip control. Is Monel harder than stainless steel? + Monel alloys are used in marine engineering, chemical processing (hydrofluoric acid, chlorinated solvents), oil and gas components, heat exchangers in seawater service, pump shafts and impellers, and valve trim in aggressive environments. Monel 405 is specifically chosen when these service requirements must be met with high-volume machined parts. Is Monel stronger than titanium? + Monel 405 round bar is the primary product form stocked for screw machine applications. Stainless Shapes distributes Monel alloy bar in multiple forms -- contact the team at 800-748-9811 for current Monel 405 inventory and sizes. Will a magnet stick to Monel? + Monel 405 provides the same base corrosion resistance as Monel 400 -- excellent in seawater, hydrofluoric acid, reducing acids, alkaline solutions, and neutral salts. The sulfur addition does not significantly degrade corrosion resistance in most service environments. Is Monel harder than Inconel? + Yes, Monel 405 is slightly magnetic. Monel alloys (nickel-copper) show slight to moderate ferromagnetism due to the nickel content. The degree of magnetism is much less than carbon steel but measurable with a strong magnet. What alloy is 75% copper and 25% nickel? + Monel 400 is more expensive than stainless steel but less expensive than Inconel alloys. Monel 405 is priced similarly to Monel 400 with a small premium for the controlled sulfur addition. Contact Stainless Shapes for current quotes. What kind of metal is Monel? + Monel 405s disadvantages include high cost versus stainless steel, limited weldability (sulfur makes welds crack-prone), inability to be hardened significantly by heat treatment, and slightly reduced corrosion resistance versus Monel 400 in creviced joints. It is a specialized grade for machined non-welded components. Is Monel 400 expensive? + Both Inconel and Monel are expensive due to high nickel content, complex alloy chemistry, and sophisticated processing requirements. Inconel grades (718, 625) are typically more expensive than Monel 400 or 405 because of additional alloying elements like niobium, molybdenum, and chromium at higher levels. Does Monel turn green? + All Monel alloys can be attacked by strongly oxidizing acids (nitric acid, concentrated sulfuric acid above ~80%), mercury and mercury salts, and moist chlorine gas. Monel is not the correct choice for these specific environments.
