Tungsten column nicekl iron WNiFe alloy is a kind of high proportion alloy material, which contains mainly over 85% tungsten and low amounts of alloy elements, such as Ni,Cu,Co,Mo,Cr, etc. Due to various characteristics and uses, WNiFe alloys can be divided into main series of W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag, etc. With a high density ranges from 16.5g/cm3 to 18.75g/cm3, WNiFe alloy is regarded as high proportion alloy material. The WNiFe alloys from Achemetal Furnace co., Ltd comply with the standard of ASTM B777-99.tungsten nickel iron
