1、Zinc alloy has the characteristics of small crystallization temperature range, low melting point, easy filling and forming, not easy to produce sticky mold, and can prolong die casting life. 2、Zinc alloy has high mechanical properties, can be die-cast a variety of complex, thin-wall castings can be a variety of surface treatment, especially with good electroplating, and has good room temperature performance. 3、Zinc alloy is easy to age, the aging surface increases in volume, the strength decreases, and the mechanical properties decrease significantly when the temperature exceeds 100 degrees. 4、The zinc alloy has a narrow operating range. When the temperature is below 0 degrees, the impact toughness decreases sharply, while when the temperature is over 100 degrees, the tensile strength can rise significantly.
