HOVADUR® Alloys

HOVADUR® alloys are vacuum-cast in a completely air-free environment, ensuring exceptional purity, homogeneity, and performance consistency. This process eliminates gas inclusions and impurities, delivering superior quality. Vacuum casting guarantees a high-quality microstructure, maximizing durability and reliability in demanding applications.

Creation process

Creating HOVADUR® Alloys

Recharging during the melting process is carried out via a lock chamber. Once the melting process being finished, the alloy is cast under vacuum into one or several moulds.

Due to this procedure under complete absence of air, a very high purity and quality of the alloy are achieved. Negative environmental influences are completely excluded.

The product line HOVADUR® B comprises our aluminium-bronzes. Due to our special processes in high vacuum, these alloys undergo a considerable improvement of their properties compared to the standard.

These alloys are particularly attractive for many applications due to their extraordinary resistance against chemical substances and their special sliding properties. Their profile is completed by the fact that they are sparking-free and show double thermal conductivity compared with steel.

SLM 3-D printing of HOVADUR® copper alloys:

Parts produced by SLM (Selective Laser Melting) may be finished conventionally by machining in the same way as semi-finished rolled or forged materials. Please observe the contours which as a rule are executed more delicately.

Besides our alloys HOVADUR® CCZ and HOVADUR® CNCS already established in the market, we shall extend our range to parts made of all other HOVADUR® alloys.

Possibilities / limits in the SLM process:

  • Ra 15 to Ra 16
  • In case of angular parts, up to Ra 60 at the bevels
  • Tolerances +/-0,3 mm

YOUR advantages:

  • Nearly unlimited freedom in constructing your parts
  • Setting of the properties according to customer specifications and application by optimized post processes
  • Homogeneous structure all along the volume of the part
