Why Choose Formotion Stainless Steel Gauges Over Our Competitors Cheaper Aluminum Made Gauges

  1. Corrosion.  Stainless steel is made up of iron, chromium, nickel, manganese and copper.  The chromium is added as an agent to provide high corrosion resistance.  Also, because it is non-porous the resistance to corrosion is increased. When aluminum is oxidized, its surface will turn white and will sometimes pit. In some extreme environments, Aluminum may corrode rapidly with catastrophic results.

  2. Thermal Conductivity.  Aluminum has a much better thermal conductivity (conductor of heat) than stainless steel. One of the main reasons it is used for car radiators and air conditioning units. The problem is, thermal conductivity is NOT what you want when it houses an instrument with sensitive components like a watch movement or temperature sensitive components like a thermometer.

  3. Cost.  Aluminum is typically cheaper than stainless steel and is a main reason why our competitors gauges are less expensive. Internal components vary greatly too. We use only Citizen / Myiota Movements and professional grade German bi-metal thermometer internals in our gauges.

  4. Thermal Properties.  Stainless can be used at much higher temperatures than Aluminum which can become soft and loosen its tolerances as temperature increases.

  5. Strength.  Stainless steel is stronger than Aluminum giving you years of uninterrupted service. That’s why our customers say they will be “handing down” their Formotion gauges to their offspring!
