Molybdenum Chemical Etching

Acid Etched Molybdenum is great for components used in environments of extreme heat. The element is a silvery-grey metal found in various oxidation states in minerals, and it can withstand extreme temperatures without expanding or softening. Molybdenum is also referred to as Moly or its element symbol Mo.

Moly is primarily mined in the U.S., China, Chile, and Peru with a world production of 200,000 tons per year.

Molybdenum 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 Molybdenum

Molybdenum is a transition metal that easily forms compounds with other elements and features the following characteristics:

  • Mohs hardness of 5.5
  • Standard atomic weight of 95.95 g/mol
  • High melting point of 2,623°C (4,753°F)
  • Low coefficient of thermal expansion
  • Boiling point of 4,800° to 5,560°C (8,600° to 10,000°F)
  • Density of 10.28 g/cm³
  • Thermal conductivity of 138 W/m at 20°C

Applications for Acid Etched Molybdenum

Most commercial Moly is used in the production of alloys to increase their hardness, strength, electrical conductivity, and resistance to wear and corrosion. Its ability to withstand extreme temperatures with its corrosion resistance and weldability makes it useful for various applications, including:

  • Aircraft components
  • Boilerplates
  • Medical imaging components

Other Factors

  • Molybdenum does not occur naturally as a free element
  • It has the sixth-highest melting point of any element
  • Readily forms hard, stable carbides in alloys, and for this reason, most of the world production of the element (about 80%) is used in Steel alloys
  • Also a micronutrient essential for life
  • Comprises 1.2 parts per million (ppm) of the earth’s crust by weight
  • Recovered as a by-product of Copper or Tungsten mining

Copper-Molybdenum Etching

Copper-Molybdenum, or Copper-Moly, is a composite material that has similar thermal properties to Tungsten-Copper. Its low density makes it suitable for applications where weight limitations are a factor. The combination of high thermal conductivity and low thermal expansion make Copper-Molybdenum perfect for semiconductor substrates, high power devices, electrical contacts, and more.
