Aluminium HTA


Aluminium HTA

Aluminium HTA - High Temperature Aluminium – is a material developed with the objective of ensuring high performance even at elevated temperatures.
HTA belongs to the Aluminium-Copper system and its excellent mechanical properties remain unchanged even at temperatures of 190-200°C.
Objects made via Additive Manufacturing using Aluminium HTA can have ultra-thin walls, with a thickness of as little as 1/1,5mm.
