Monel Fastener


Amco metals can provide a wide variety of Monel fasteners including; Monel nuts, Monel bolts, sockets, washers and more Monel Fasteners. If we do not have your Monel Fasteners in stock (Inch or Metric) we can have these manufactured to your specification.

Material Notes:

Monel is primarily composed of nickel (up to 67%) and copper, with some iron and other trace elements.Monel alloy 400 is a binary alloy of the same proportions of nickel and copper as is found naturally in the nickel ore from the Sudbury (Ontario) mines.

Properties:

Compared to steel, Monel is very difficult to machine as it work-hardens very quickly. It needs to be turned and worked at slow speeds and low feed rates. It is resistant to corrosion and acids, and some alloys can withstand a fire of pure oxygen. It is commonly used in applications with highly corrosive conditions. Small additions of aluminum and titanium form an alloy (K-500) with the same corrosion resistance but with much greater strength due to gamma prime formation on aging. Monel is typically much more expensive than stainless steel.

Monel alloy 400 has a specific gravity of 8.83, an electrical conductivity of approximately 3.4% IACS, and (in the annealed state) a hardness of 65 Rockwell B.

Aerospace applications

Monel metal found bulk uses in aircraft construction, especially in making the frames and skins of experimental rocket planes, such as the North American X-15, to resist the great heat generated by aerodynamic friction during extremely high-speed flight. Monel metal retains its strength at very high temperatures, allowing it to maintain its shape at high atmospheric flight speeds, a trade-off against the increased weight of the parts due to Monel's high density.

Marine applications

Monel's corrosion resistance makes it ideal for marine applications such as piping systems, pump shafts, seawater valves, trolling wire, and strainer baskets. Some alloys are completely non-magnetic and are used for anchor cable aboard minesweepers, housings for magnetic-field measurement equipment. In recreational boating, Monel wire is used to seize shackles for anchor rodes, Monel is used for water and fuel tanks, and for underwater applications. It is also used for propeller shafts and for keel bolts. However, because of the problem of electrolytic action in salt water (also known as Galvanic corrosion), in shipbuilding money must be carefully insulated from other metals such as steel.

K-500 Alloy has similar properties to Monel 400 Alloy but has the added feature of Age Hardening to achieve a higher strength and hardness, this is due to the addition of aluminum and titanium. K-500 Alloy's strength is maintained at temperatures as high as 1200 F, yet stays tough and ductile to temperatures down to -423 F. Along with staying non-magnetic down to -210 F. A common specification for this is QQ N 286.

A fastener is a hardware device that mechanically joins or affixes two or more objects together.

Fasteners can also be used to piping components such as a valve, pumps, or a maintenance flange; or they may involve keeping together the sides of an opening of flexible material, attaching a lid to a container, etc.

Fasteners used in these manners are often temporary, in that they may be fastened and unfastened repeatedly.
