HPM1810 tungsten alloy rod has high density, which is the prime choice for adding balance weights, ballast or vibration damping mass where space is limited. It is reasonably corrosion resistant in both acid and alkaline environments and can easily be plated or painted if necessary. It is easy to clean, non-toxic and non-radioactive.
