Non-magnetic Tungsten Carbide Ball

non-magnetic tungsten carbide ball


Non-magnetic tungsten carbide means no magnetic or weakly magnetic carbide materials, Non-magnetic tungsten carbide ball with the properties of non-magnetic and the high density of tungsten carbide, as the hardness, T.R.S., impact toughness, corrosion resistance are hihger than other material, which are used in thermal recovery wells and sand wells areas.


High hardness, high T.R.S., high impact toughness and high corrosion resistance.


Widely used in thermal recovery wells and sand wells areas.
