COF

Examples
For example, a copper pin sliding against a thick copper plate can have a COF that varies from 0.6 at low speeds (metal sliding against metal) to below 0.2 at high speeds when the copper surface begins to melt due to frictional heating.
For example, silicone rubber or acrylic rubber -coated surfaces have a coefficient of friction that can be substantially larger than 1. While it is often stated that the COF is a "material property," it is better categorized as a "system property."
From 2007–2012, Ms. Tomlin held several senior leadership positions, including vice president of marketing, with Capital One Financial Corp. (NYSE: COF), where she headed commercial banking, retail marketing and sponsorships.
The latter speed, of course, does not determine the COF uniquely; if the pin diameter is increased so that the frictional heating is removed rapidly, the temperature drops, the pin remains solid and the COF rises to that of a 'low speed' test.
