Compensating for oscillations, weight transfers, imbalances and vibrations, and creating or shifting centres of gravity, balancing weights made from the tungsten heavy metal composite Densimet® ensure the optimum balance.
With their high densities of up to 18.89 g/cm3, Densimet® tungsten heavy metal alloys offer exceptional performance wherever a lot of weight has to be accommodated in a limited space.
For example, in propeller and helicopter blades, rudders, radar equipment and avionics systems in the aviation and aerospace industries, the tungsten composite material Densimet® has proven its exceptional capabilities.
Furthermore, balancing weights made of the tungsten heavy metal composite are used on crankshafts or in balance shafts in formula 1 racing cars or large diesel engines. In addition, these tungsten heavy metal alloys are a perfect material choice for damper and absorber components in the drive train, thanks to their high density, high modulus of elasticity and optimised ease of mechanical processing.
Overall, balancing weights play a central role in many different applications. As they contribute to reducing the loads which individual components are subject to, they ultimately help to increase their service life.
Here are some examples:
• Propeller and helicopter blades in the aviation and aerospace industry
• Crankshaft counterweights and chassis weights in the automotive industry
• Bobs on watch rotors in the watch industry
• Golf clubs and other sports equipment
• Microscopes and measuring instruments in the optical industry
• Downhole logging tools in the oil and natural gas industry
The brittleness of pure tungsten is overcome by adding nickel and iron to the composite materials and applying the molten material in a liquid-phase sintering process. With the nickel-iron phase binding the tungsten grains, high ductility is guaranteed. This ultimately leads to the material offering optimised mechanical processing capabilities and being able to withstand high loads.
Thus, these balancing weights are especially suited for applications in the watch industry as they are highly dense while still be easily processable. Furthermore, thanks to the possibility to shape these weights in complex geometries, they are also applied to balance microscopes and high-precision optical instruments as well as to other products in the semiconductor industry.
Plansee is entirely focused on producing, processing and marketing refractory metals such as tungsten, tantalum and molybdenum. These are the most heat-resistant metals. With their high melting point, they are suitable for use as heaters in high-temperature furnaces or as incandescent filaments in lamps. In electrical switch contacts, they are valuable because of their excellent electrical and thermal conductivity. In electrically conductive film in flat screens and solar cells, our alloys are remarkable for their low coefficient thermal of expansion. In this way, they bring astonishingly sharp image quality to our living rooms and provide us with clean energy.
