AZ25 is an electro-fused alumina-zirconia grain, produced by fusing alumina and zirconia raw materials at about 2000 ℃ temperature in an electric arc furnace. Following a unique process of quenching, crushing, and resizing, we produce the distinct characteristics and the exact grain measurements. AZ25 is extremely wear resistant and anti-friable grain that is widely for bonded abrasives.

AZ25 is a dense, durable material frequently used to produce heavy-duty bonded abrasives.widely for bonded abrasives.

AZ25 is extremely tough and hard with blocky shape and is re-shaped based on the original AZF25 material. It is frequently used for producing extra-duty bonded abrasives for steel conditioning industry.
