Monel Chemical Etching

Monel chemical etching is a process for thin metal parts in aerospace, marine, and chemical industries. It is a group of Nickel alloys, primarily composed of Nickel (52 to 62%) and Copper, with small amounts of Iron, Manganese, Carbon, and Silicon. Stronger than pure Nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater. Contact us today for more information on Acid Etch for Monel Parts!

Monel Chemical Etching

Fotofab’s etching process produces designs that can withstand harsh indoor and outdoor environments. The process uses a strong caustic chemical to etch into unprotected parts of a metal surface to create a design or image formed to your project’s specifications.

Characteristics of Monel

Monel is a solid-solution binary alloy that can be hardened only by cold working. Other characteristics include:

  • Difficult to machine as it work-hardens quickly
  • Resistant to corrosion and acids
  • Robust over a wide temperature range
  • Hardness of 65 Rockwell B in an annealed state
  • High density
  • Ductile and malleable
  • Low coefficient of thermal expansion
  • Rust resistant
  • High mechanical strength
  • Stronger than Steel

Acid Chemically Etched Monel Applications

Monel’s resistance against corrosion and acids makes it a good material for aerospace, marine, and chemical applications, including:

  • Aircraft construction including frames and skins
  • Safety wire in aircraft maintenance
  • Marine engineering
  • Components for magnetic-field measurement equipment
  • Recreational boating
  • Chemical and hydrocarbon processing equipment
  • Heat exchanges

Other Factors

  • Monel can be fabricated by hot- and cold-working, machining, and welding
  • Monel needs to be turned and worked at slow speeds and low feed rates
  • Typically, more expensive than Stainless Steel
  • Does not undergo ductile-to-brittle transition even when cooled to the temperature of liquid hydrogen
