materials and applications

Bronze

Prototypes from Quick Sand Casting and DMLS Interacting

We produce prototype bronze castings for specific applications such as:

  • Nautical details such as propellers, azimuthal pod systems, waterjets, etc.
  • Details for food industry machines such as mixing arms, augers, baskets etc.
  • Details for the construction of explosion-proof / anti-spark machines such as impellers, shims, casings, carters, etc.

Below are some of the most used alloys to serve these needs.

Features

average data of the Bronze materials obtained

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