High density tungsten alloy balls (Density 18g/cm3)
TSS tungsten super shot for hunting
Tungsten nickel iron/copper(WNiFe&WNiCu) alloy balls/shots
Material: W90NiCu, W90Ni7Fe3, W92NiCu, W92.5NiFe, W95NiFe, W97Ni2Fe1
1) Density of tungsten shot: 17g-18.5g/cm3
2) Available size: Dia: 2.0mm,dia2.25mm,dia2.5mm,dia3.0mm,dia3.5mm,dia4.0mm,dia4.5mm,
dia5.0mm,dia5.5mm,dia6.0mm,dia6.5mm and so on,the biggest size is dia15mm.
High density, great hardness and resistance to high temperature make tungsten to be one of the most sought
-after material for shotgun pellets in hunting history. Density of tungsten alloy shot is about 18g/cm3, which is
comparable only to gold, platinum, or bismuth.
