Material Notes:
Description of Product: Tungsten based composite materials are outstanding due to high density and good mechanical properties. The product can be delivered both as semi-finished product for further processing by the customer or in accordance with the drawing as finished machined component.Our HPM 1700 to HPM 1850 materials provide a solution in a wide range of applications requiring concentrated weight or density in a limited space. These lead-free parts meet legal requirements and recommendations to protect the environment.Range of Application: Balance weights, radiation protection, vibration absorbers, heat transfer, drilling bars. The mechanical characteristics have to guarantee the stability and strength in any application case.The absorption of x-ray and gamma radiation is in direct proportion to the density of the shielding material. Tungsten high density composites are more than 1.5 times as effective as lead and provide extremely efficient protection, particularly where space is limited.Information provided by H.C. Starck.
