materials and applications

Aluminum

Prototypes from CNC milling, casting, Quick Sand Casting, DMLS Sintering

The alloys used are aluminum-silicon. To guarantee the best result in terms of casting success, only primary alloys are used. Effect of alligers:

  • Si: it improves the fluidity of the molten alloy. A higher silicon content makes it possible to obtain jets with thinner walls, but increases the risk of abnormal shrinkage in massive areas.
  • Cu: improves compactness and heat dissipation.

To improve workability it is advisable to subject the parts to heat treatment cycles T6 (which also raise the set of mechanical characteristics).

Features

average data of the aluminum 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.
