Eco-friendly aluminium alloy that can be cast even at a low temperature


This alloy has higher fluidity than ADC12. (Graph 1)

Graph 1. Comparison of flow length between ECA2 and ADC12 (MIT fluidity test)


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.

Graph 2. Comparison of liquidus temperatures


It has excellent wear resistance. (Graph 3)

Graph 3. Comparison of wear resistance


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.


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.


It has a higher proof stress than ADC12. (Table 3)
