High quality stability with no internal defect from homogeneous structure.

Excellent corrosion/Erosion resistance for molten metal and flux as they have low porosity and small pore size distribution.

Excellent spalling resistance which is induced by high strength.

High energy saving with reduction of melting hours by high thermal conductivity.

High oxidation resistance with good coating which is induced from homogeneous structure and high density.

Induction furnaces, especially high frequency induction furnaces are good application for them as they have homogeneous structure.
