tungsten carbide saw teeth for wood-cutting
Cobalt-base alloys comprise complex carbides in an alloy matrix. Their exceptional wear resistance is due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix.
Saw tips are made of CoCrW12, so the following information is all about CoCrW
12.
(1). CoCrW12 could be considered an intermediate alloy.
(2). It contains a higher fraction of hard, brittle carbides than UNS R30006
(3).It has increased resistance to low-angle erosion, abrasion, and severe sliding wear while retaining reasonable impact and cavitation resistance.
(4). CoCrW12 is often used self-mated or running against.
