Carbides and Carbide Materials (hardmetals) Selection …

11/8/2020· Boron carbide (B 4 C) has higher hardness than alumina or silicon carbide. Its oxidation product (B 2 O 3 ) provides a protective skin at high temperatures (> 800 o C). Because of its high hardness and wear resistance, boron carbide is applied in low-temperature appliions such as grinding wheel dressers, and abrasive blast or water jet nozzles.

Carbide Types in Knife Steels - Knife Steel Nerds

15/7/2019· Silicon carbide has a similar hardness to those hard carbides but is not clearly harder, and in general silicon carbide is not as good at cutting steel as aluminum oxide. CBN and diamond are significantly harder than any of the carbides so they are generally better at least in terms of grinding and polishing high wear resistance steels with hard carbides.
