Get the most out of it. With DENSIMET® WR.
Rapid heat dissipation.
Short cycle times. Optimum quality.
In addition, thanks to the rapid heat dissipation, the microstructure (dendrite arm spacing) of the aluminum castings is significantly finer. This in turn helps optimize the mechanical properties of your products, for example by increasing their strength.
High corrosion resistance. Long service life.
Compared to steel, mold inserts made from DENSIMET® are particularly erosion and corrosion-resistant. Because our material does not react with the aluminum melt, no metal residues continue to adhere to the mold insert, for example when the castings are removed. The benefit to you: The inserts can be used for longer, do not have to undergo time-consuming cleaning operations and are soon ready for the next pouring.
Low thermal expansion. No cracks.
Because during casting, the aluminum melts come into contact with the colder surface of the mold insert, thermal fatigue cracks may form in the material. This can cause cracks in the mold, in particular during high-pressure casting. The coefficient of thermal expansion of DENSIMET® is approximately a third lower than that of steel. In combination with the high conductivity of DENSIMET®, this means that there is no danger of cracks forming in the mold insert during the casting process.
Sure and certain.
|Since 1921, our customers have been able to rely on PLANSEE as an independent private company. For our customers and for us, reliability and continuity is particularly important when it comes to the supply of raw materials. With Global Tungsten & Powders (GTP) and its interest in Molibdenos y Metales (Molymet), the Plansee Group covers every step of the molybdenum and tungsten processing – from powder production through powder-metallurgical processes to serving customers with semi-finished and tailor-made components.|
Three paths. One goal. The perfect alloy.
