Fehrmann Alloys to exhibit AlMgty high-performance alloy at Formnext 2019

November 10, 2019

Fehrmann Alloys GmbH & Co KG, Hamburg, Germany, a combined venture of Fehrmann GmbH and Cremer, will exhibit its metal alloys for Additive Manufacturing at Formnext 2019, Frankfurt, Germany, November 19–22. The company recently launched a new high-performance aluminium alloy titled ‘AlMgty’, for which market launch is expected in 2020.

The new AlMgty aluminium alloy can be used for metal Additive Manufacturing, sand casting, pressure casting and mould casting. The mechanical properties of AlMgty are said to remain very similar in all processes, so that components made of the same alloy can be produced additively as prototypes or in small series, and can also be mass-produced by die casting.

AlMgty is said to offer tensile strength of 355 Mpa, yield strength of 220 MPa, and elongation of 19% as-built. It is resistant to corrosion and anodizable, and does not rely on expensive alloying components such as scandium. Because only generally available components are used to make the alloy, there is also less risk of supply problems due to low availability or extraction conditions that are hard to control, as with scandium.

Fehrmann Alloys reports that it has received its first order for the new material from Hamburg-based Ziegelmayer, a manufacturer of racing sailboats such as the Olympic 470 yacht. The company has commissioned Fehrmann Alloys to reconstruct the rudder mounting for a yacht using additively manufactured AlMgty.

This process will be completed by Andreas Wiesner, former head of R&D at SLM Solutions and now owner of the firm AM & Research. Fehrmann Alloys will reveal a complete comparison of weight and costs at Formnext.
