Frequently asked questions
What sizes do the bars come in?
What sizes do the bars come in?
Most bars are square cross-sections from 0.25 inch up to 2.25 inch, in 12 inch lengths, plus select rectangular and cut pieces. Availability varies by alloy — MT-17F and MT-185 carry the fullest size runs.
Which alloy should I choose?
Which alloy should I choose?
Density and binder. The 90% tungsten grades (MT-17C, MT-17F, MT-17D) run 17 g/cm³, the 95% grades (MT-18C, MT-18F) run 18 g/cm³, and MT-185 at 97% tungsten reaches 18.5 g/cm³. All conform to ASTM B777, and trade names such as HD 17, CMW 2000, and K1800 cross-reference to the same grades.
How heavy is a bar?
How heavy is a bar?
A 1 inch square MT-185 bar 12 inches long weighs about 8 lb; a 2.25 inch square bar in MT-17F is about 17 lb.
Is tungsten alloy bar easy to machine?
Is tungsten alloy bar easy to machine?
Much easier than pure tungsten. The nickel-iron or nickel-copper binder gives the alloy enough ductility to machine well with conventional shop tooling, which is why it's a staple for machine shops, labs, and DIY machinists.
Are the edges finished?
Are the edges finished?
Bars ship with sharp, unrounded edges. Tolerances are ±0.002 inch on the cross-section and +0.060/-0 inch on length.
