British Firms Explore Heat Treatment Regimens for Alloy in Additive Manufacturing

Two British firms recently announced a collaboration to establish process parameters for the use of aluminum alloy in additive manufacturing (AM), a project that will include the investigation of heat treatment regimens to deliver optimum properties in AM components for applications in multiple industries, including the aerospace sector.

Renishaw, a global engineering technologies company based in Gloucestershire providing solutions and products for the aerospace, medical, energy and manufacturing sectors, and Worcestershire’s Aeromet International, a leading supplier of cast metal parts for the global aerospace and defense industries, recently debuted the highly refined alloy at the Paris Air Show in June. The two companies are working together to establish additive manufacturing process parameters and material properties for Aeromet’s A20X® aluminum alloy and to optimise the processing techniques for the alloy on Renishaw metal AM systems.  The results of these developments and the heat treatment research will be made available to Renishaw and Aeromet customers.

A family of high-strength aluminum alloy technologies developed and patented by Aeromet, A20X® includes the Metallic Materials Properties Development and Standardization (MMPDS) approved A205 casting alloy and AM205 powder for additive manufacturing.

“A20X is being rapidly adopted for additive manufacture of aero engine, airframe, space, defense and automotive parts.  It’s unique combination of high strength, high ductility and performance at high operating temperatures make it ideal for light-weight, stressed components.  We look forward to making processing techniques for this innovative alloy more widely available to accelerate its adoption,” said Mike Bond, Director of AMT a Division of Aeromet.

“Renishaw’s metal AM systems feature high-power lasers, an inert processing environment, and open parameters,” said Marc Saunders, Director of Global Solutions Centres at Renishaw, “making them ideal for supporting innovative new materials like A20X.  We are working closely with Aeromet to qualify this exciting new alloy on our machines. Through our network of AM Solutions Centres, we can help manufacturers to develop industrial AM processes using A20X.”

The two companies plan to release processing techniques and material properties information in the coming months.
