Description
The highly polished carbon planchets have a smooth, polished finish on one side with much less surface porosity than the standard carbon planchets.
The material for the cabon discs is spectroscopically pure carbon Grade 1 (soft graphite) with total impurities equal to or less than 2ppm with each single element 1ppm or less.
Properties same as Carbon Planchets above.
The polished planchets are 1.4 to 1.5mm (0.055″ to 0.06″) thick.
Available in the popular 12.7mm (1/2″) and 25.4mm (1″) diameter.
