Features
Eco-friendly aluminium alloy that can be cast even at a low temperature
1
This alloy has higher fluidity than ADC12. (Graph 1)
2
It has a low liquidus temperature (561°C) and can be cast at a low temperature. (Graph 2)
It has a proven track record with respect to die casting at a casting temperature of 600°C.
3
It has excellent wear resistance. (Graph 3)
4
It can be cast at low temperatures to extend the lifespans of dies.
It can be filled at low speeds, and a T6 treatment can be applied by low-speed (laminar flow) filling.
5
Low casting temperatures also reduce the use of mold release agents.
Regarding test molds, this alloy has a track record with respect to casting without the use of mold release agents.
6
It has a higher proof stress than ADC12. (Table 3)
