ARTIRUNDUM© is manufactured in three main series (A-Series, S-Series and M-Series) to provide different crystal characteristics and chemical compositions. Each series is further configured into many other types by undergoing different processing and treatments to enhance the characteristics and performance.
A-Series
A-Series is regular titanium fused alumina. The crystals are dense and big to provide high toughness for large stock removal that are most widely used. The product codes begin with “AO” or “AC” like AOAD and ACB.

S-Series
S-Series is low titanium semi-friable fused alumina. The crystals are big but not too tough for fast cutting while to allow working in heat sensitive conditions. The product codes begin with “S” like SFR and SF.

M-Series
M-Series is high purity mono-crystal fused alumina. Many of the grains are existed in single crystal form so that they are tough enough against tear strength for long usage life while they are able to work in heat sensitive conditions. The product codes begin with “M” like MCFA.
