Notes:  
Machined with tungsten-carbide tools. Inherent wear resistance, resistant to the wearing effects of hard, sharp particles such as in screw conveyors, rock crushing rollers, tile-making machines, and cement and steel-mill equipment. Resistant to the effects of seizing or galling, low coefficient of friction alloys sliding contact with other metals. Used in equipment where no lubricants are used. Outstanding resistance to cavitation-erosion. Combines wear and corrosion resistance with good impact strength and resistance to thermal shock. Retains high hardness, even at red heat. Electrical conductivity 1.90% compared to Copper. 2360 MPa average modulus of rupture of sheet at room temperature.
