＊Flat die casting sample (50 x 100 x 5 mm)
＊Test period: 720 hr (n=3)
- Melting temperature: A temperature from 680 to 700°C is recommended, although it also depends on the casting design.
- Flux: Flux for ADC12 is acceptable.
- About the use of return materials
(1) When priority is given to mechanical properties
Return materials cannot be used because attenuation of Mg and Sr causes the mechanical properties to change. However, they can be used if an analysis of Mg and Sr indicates that the addition of return materials is possible.
(2) When priority is given to corrosion resistance
Return materials can be used. Use of return materials does cause attenuation of Mg and Sr, but it does not affect the corrosion resistance.
