Filling Grains

1. High hardness

It Rockwell hardness is HRA80-90, second to only diamond and far better than wear-resistant steel and stainless steel.

2. Good wear-resistant performance

Its wear resistance is 266 times that of manganese steel and 171.5 times that of high chromium cast iron. From our customer follow-up over the past decade, under the same load, it can extend the equipment service life by at least 10 times.

3. Low density

Its density is 3.6-3.65g/cm3, just half of iron and steel, which greatly reduces the equipment load.

Application: Widely used in aluminum filter furnaces as  fillers.
