The dimensional accuracy of castings is high, generally equivalent to level 6~7, or even up to level 4; the surface finish is good, generally equivalent to level 5~8; the strength and hardness are high, and the strength is generally 25~30% higher than that of sand casting. However, the elongation is reduced by about 70%; the dimensions are stable and interchangeable; and thin-walled and complex castings can be die cast.
