About aluminum

Aluminum is a strong, light-weight metal alloy that combines outstanding mechanical and thermal properties. For those reasons, aluminum alloys are one of the most popular metals in the world, being widely used in the aerospace, automotive and biomedical industries.

The remarkable characteristics of this metal material make it a great choice for high-performance functional parts that are exposed to high loads. Aluminum alloys are also suitable for engine parts, production tools as well as for specific heat exchanger and outdoor applications.

The material can be used for both prototyping and manufacturing purposes. The quality of parts that are 3D printed in Aluminum are as good as parts manufactured with CNC.

Available aluminum alloys:

  • AlSi10Mg – Aluminum with silicone (10%) and magnesium alloys;
  • AlSi12 – Aluminum with silicone alloy (12%);
  • AlSi7Mg – Aluminum with silicone (7%) and magnesium alloys;
  • AlSi9Cu3 – Aluminum with silicone (+/-9%) and copper (+/-3%) alloys;

Strengths

✦ High performance material with remarkable mechanical properties

✦ Complex geometric structures

✦ Ideal for both prototypes and end-parts

✦ Great strenght-to-weight ratio

✦ Weather resistant / No rust

Weaknesses

✧ 2.7 times less rigid than a construction steel

✧ Not biocompatible
