Copper is a relatively soft and easy to cut material, however it has the potential to be easily damaged during typical machining. Microphoto’s team of experts work with multiple copper alloys, including:

  • C110
  • C101/102 Oxygen Free Coppers

Beryllium Copper

Beryllium copper is comprised of copper alloy and 0.5-3% beryllium that make it highly ductile, an excellent conductor of electrical current, and abrasion resistant material. Beryllium Copper is a known carcinogen when the dust that can be caused by traditional machining processes is inhaled. This is not an inherent hazard with our photochemical machining process. We specialize in high precision and tolerance beryllium copper parts used in various electrics applications. The Beryllium copper alloys we work with include:

  • C17200
  • C17419
  • C17510


Brass is a copper-zinc alloy that provides excellent strength, hardness, ductility, conductivity, corrosion resistance, and more. Brass is commonly used in applications for electronic or decorative components with the ability to come in a variety of colors. Copper alloys that we work with include:

  • C260
  • C220
  • C210


Aluminum offers high strength and natural corrosion resistance at a lower cost, making it a well-suited material for aerospace and aeronautic application. Here at Microphoto, we specialize in numerous aluminum alloys, including:

  • 6061
  • 5052
  • 2024
  • 3003
  • 1100

Nickel Alloys

Nickel is commonly used for its heat resistance and capability to withstand excess corrosion. Nickel components can be used in a variety of industries, including the medical and electronics industries. Nickel alloys we work with include:

  • 200
  • 201
  • Monel 400
  • Nichrome 80
  • Inconel x750
