A new, high strength option for aluminium additive manufacturing

A20X™ POWDER

A20X™ powder for laser powder bed fusion (LPBF) has been developed for high strength production components to be used in the most demanding applications. Excellent high temperature properties, stress corrosion resistance and significantly better fatigue properties when compared to Al-Si based additive manufacturing alloys.

Originally developed as a casting alloy, A20X™ is now available for use in laser powder bed fusion additive manufacturing. Suitable for use with all leading brands of AM equipment, A20X™ powder has produced parts with up to 511MPa UTS and over 13% elongation.

Mechanical

A20X™ powder for additive manufacturing can produce mechanical properties unrivalled by aluminium-silicon-magnesium alloys. Typical properties for additively manufactured parts go up to 511MPa UTS, 440MPa yield and 13% elongation.

 

Temperature

A20X™ powder is derived from the advanced A205 aluminium-copper-TiB2 alloy, giving A20X™ additively manufactured parts superior temperature performance compared to aluminium-silicon-magnesium powders.

 

Powder Characteristics

A20X™ powder is optimised for laser powder bed fusion additive manufacturing with particle size range 20-63 microns.

The gas atomisation process used to produce A20X™ powder results in spherical, uniform powder with flowability suitable for use in all leading powder bed AM systems.
