Bronze

Prototypes from Quick Sand Casting and DMLS Sintering.

Prototype bronze castings are made for specific applications such as:

  • Nautical details such as, propellers, azimuth pod systems, hydrojets, etc.
  • Parts for food industry machines such as mixing arms, augers, baskets, etc.
  • Parts for the construction of explosion-proof/anti-sparking machines such as impellers, washers, casings, crankcases, etc.

The following are some of the most commonly used alloys to serve these needs.

Features
Average data obtained from bronze alloys

In prototyping, the combination of material and processing technique is one of the most complex choices. Making a prototype from bronze alloys almost always requires evaluations so, for the use and consumption of engineers, average characteristics of materials obtained by prototype construction are given. These can be used to get an idea of technical and functional compliance.
