Abstract

The invention relates to an abrasive grit essentially comprising sintered alumina, characterised in comprising more than 96 % by weight of alumina, between 0.1 and 3 % by weight of titanium oxide and between 0.1 and 3 % by weight of manganese oxide, the sum of titanium oxide and manganese oxide remaining less than 4 % by weight. The content by weight of titanium oxide and/or manganese oxide is preferably more than or equal to 0.5 %, also the content by weight of titanium oxide and/or manganese oxide is less than or equal to 1.3 %.
