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.
