The below specifications include an important section on the material specifications as these significantly impact far more the precision in the game than the dimensional aspects. |

1. Material specifications
Resin characteristics
- Resin type : genuine Aramith resin
- Aramith resin : 100% HD (high-density) phenolic resin
- Density : from 1.69 up to 1.87 depending on Aramith resin type
- Density tolerance : +/- 0.015
- Density dispersion : evenly dispersed throughout ball and parts
- Hardness : > 73 HRH (Super Aramith PRO : >80 HRH)
- Hardness variation : no variation (constant over all ball parts and surface)
- Duramith™ technology : included in the high end sets > Learn more
Surface characteristics
- Surface : vitrified surface
- Vitrification technology : Vitrotech™ by Aramith
- Surface rugosity : average Ra = 0.03 microns
- Surface finish : high gloss polish
Dynamical characteristics > Learn more
- Rebound : constant within the set
- Anti-Kick™ properties : highly anti-static to minimize kicks, buttages & skids
- Balance (density dispersion) : constant throughout the ball sections
- Surface elasticity : constant over ball
Durability
- Impact resistance : over 4.000.000 hits
- Burn spot resistance : resists to 250°C break shot instant friction temperatures
- Cloth wear : minimal, as Aramith keeps its smooth surface and avoids white marks
- Lifetime : up to 5x longer (more with Duramith™ Technology)
2. Dimensional specifications
- Billiard ball diameter range : from 1” up to 2-3/4”
- Tolerance standard : better than Precision Plastic Ball GRADE III specification limits
- Most common diameter (") :
- Nominal : 2-1/4
- Diameter tolerance : max +/- 0,003
- Sphericity / roundness : max 0,002 (high end grade : max 0,0012)
Note : Some specifications are resin type and diameter specific.
