Tungsten Heavy Alloy Bar
Tungsten heavy alloy bar (WNiFe, WNiCu alloy)according to standard ASTM B777 , AMS- T 21014 , density HD 17 , HD 17BB , HD 17D , HD 17.5 , HD17.7 , HD 18 , HD 18D , HD 18.5 g/cm3 , including 90WNiFe, 93WNiFe , 95WNiFe , 97WNiFe , 90WNiCu, 93WNiCu , 95WNiCu , 97WNiCu etc.
- Description
Tungsten alloy bar is produced by pressing and sintering metal powders into billets, which are worked by rolling or swaging into rod. Smaller sizes are produced by subsequent drawing. Tungsten alloy rod is produced in straight random lengths with a smooth swaged surface at diameters 3mm and larger, and with a smooth drawn finish below 3mm. A centerless ground finish can also be furnished. Specific lengths and special fabrications can be supplied upon request.
