Expertise in a variety of materials for diamond turning and precision engineering

Experience counts when selecting the right materials

Using a single-point diamond tool to produce high-precision components with a fine surface finish requires an understanding of the proper materials.  The material being machined must be chosen carefully to ensure that it can be cut effectively with a diamond tool. Hard materials require different diamond grades or cutting parameters than softer materials. Nanophorm has experience with nearly every “diamond-machinable” material, along with plating for those that are not.

Metal Alloys

These materials are often used in applications that require high strength and durability.

  • Aluminum alloys – 6061 and 2024 being the most common
  • Copper alloys – type 101 OFHC and 110 being the most common
  • Brass
  • Bronze
  • Beryllium Copper alloys such as MoldMax HH
  • Tin
  • Antimony

Polymers

These materials are often used in optical components due to their optical clarity and low cost.

  • PMMA – Acrylic
  • COP – Zeonex
  • Polystyrene
  • Polycarbonate
  • PEI – Ultem
  • COC – APEL, Topas
  • Polyester – OKP1, OKP4, OKP4HT
  • Polystyrene – Rexolite 1422

Optical Crystals and Chalcogenides

These materials are often used in optical and high-precision applications due to their optical clarity and high thermal and mechanical properties.

  • Germanium
  • Zinc Selenide
  • Zinc Sulfide
  • Chalcogenide Glasses – Schott ID Glass
  • Indium Antimonide, Mercury Cadmium Telluride
  • SiliconĀ 
If your material is not “diamond turnable” but you still require the same capabilities, you might consider consulting with us about plating your materials. These materials adhere to most “non-diamond-turnable” materials and allows the same mirror finish:
  • Alumiplate
  • High-phosphorous Electroless Nickel Plating
  • Copper – Nickel Plating
  • Copper Plating
This is a list of materials we have worked with. Please contact us if you have questions about alternative materials. We can almost certainly help.
