BRAND NT®	Weld metal Standard analysis, %		Hardness	Applications and Properties	Process
NT® NiBSi+WSC	C Si Ni B W	2,3 1,8 37,6 1,8 Remainder	> 60 HRC	Mixture of self-flowing NiBSi alloy of medium hardness (50 HRC) with angular tungsten carbides in a ratio of 40/60; increase in hardness by dispersion of tungsten carbide in the matrix for effectively enhancing the wear resistance; excellent working and machining properties by virtue of the self-flowing feature; alloy concept very well suited for components subject to extremely severe wear, such as tools employed in open-pit mining or oil production; highly economical operation because of the very long service life	PTA PS HVOF
NT® NiBSi+WSC-S	C Si Ni B W	2,3 1,8 37,6 1,8 Remainder	> 60 HRC	Similar to NT® NiBSi+WSC, but containing globular tungsten carbides in a ratio of 40/60; improved wetting properties in the matrix in comparison with angular tungsten carbide	PTA PS HVOF
NT® NiCrBSi+WSC	C Si Ni Cr B W	2,5 2,6 Remainder 9,6 2,1 38,0	> 60 HRC	Mixture of very hard (60 HRC) self-flowing NiCrBSi alloy with angular tungsten carbides in a ratio of 60/40	PTA PS HVOF
NT® NiCrBSi+WSC-S	C Si Ni Cr B W	2,5 2,6 Remainder 9,6 2,1 38,0	> 60 HRC	Similar to NT® NiCr-WSC, but containing globular tungsten carbides in a ratio of 60/40	PTA PS HVOF
