MT-17C: (-0/+0.003" dia) (-0 length) 17g/cc density. 90% Tungsten, 6% Nickel, 4% Copper. High quality tungsten heavy alloy (W) rod in 12" lengths conforms to international standard ASTM B777, Grade 1, Type II & III. All material is lot controlled, stress relieved, and formed through high temperature pressing and sintering processes. This rod is perfect for machine shops, labs, research and development, and DIY machinists. Tungsten alloy is much easier to machine than traditional pure tungsten. Other material names that match the same ASTM standard: HA170C, HD 17, Dens21, CMW 1000, K1701, M1000

MT-17D Die Alloy (-0/+0.003" dia) (-0 length) 17g/cc density. 90% Tungsten, 4% Nickel, 4% Molybdenum, 2% Iron. High quality tungsten heavy alloy (W) rod in 12" lengths. All material is lot controlled, stress relieved, and formed through high temperature pressing and sintering processes. This alloy is specifically designed for die casting. It will extend your die life, make castings faster, and lead to fewer rejects. Tungsten alloy is much easier to machine than traditional pure tungsten.

MT-17F: (-0/+0.003" dia) (-0 length) 17g/cc density. 90% Tungsten, 7% Nickel, 3% Iron. High quality tung
