Outstanding properties of aluminium are

  • the low weight and high strength
  • the good conductivity of electricity and heat
  • a particular corrosion resistance among other to water or chemicals




Magnesium is an excellent die casting material.

Compared to aluminium, magnesium has a number of advantages:

  • Improved castability
  • Low part weight
  • Thin walls
  • Increased mould service lives


Materials competence with innovative strength

Aluminium and magnesium are the construction materials for the intelligent development of lightweight components.

We process all popular aluminium alloys at our four production locations in Biberach, Annaberg, Košice and Tianjin. At our new magnesium production facility in Biberach, we additionally use special magnesium alloys.

Information on the mechanical characteristic values and the alloy compositions can be found in our Handtmann alloy table.

Materials validation

Handtmann avails itself of innovative means, especially in the technology sector. The materials testing and validation always ensures the flawless quality of our products.

Handtmann - CT-analysis

Handtmann - CT-analysis

  • Computed tomography CT
    We have a state-of-the-art inline CT system for the non-destructive 3D component characterisation of light metal alloy workpieces. This method not only allows automatic in-process inspection of cast parts for three-dimensional detection of defects within a short time, but also to monitor custom defect characteristics
  • X-ray inspection (2D)
  • Three-dimensional analysis of surface profiles and roughness by means of structured light projection
  • Eddy current testing (layer thickness measurement)
  • Fluorescent dye penetrant testing
  • Dye penetrant testing


Handtmann - analysis

Handtmann - analysis

Compliance with and fulfilment of specifications requires the correct chemical composition of the components. This is achieved through continuous analysis of the melts as well as incoming checks.

For this purpose, we have state-of-the-art simultaneously measuring spectral analysis devices for the analysis of Al, Mg, and Fe materials.

Handtmann - metallography

Handtmann - metallography

Metallographic examination methods are used for qualitative
and quantitative assessment in the process check and monitoring,
damage examination as well as in the development of technical materials.

  • Structural evaluation
  • Pore analysis
  • Quantitative image analysis
  • Layer thickness measurement
  • Fracture surface evaluation
  • Inspection of welded joints
