Zinc Alloy Ingot
- Specification：鋅合金2, 3, 4, 5, 7, 8, 12號料(中鋼鋁)
- Applications：The main added elements of zinc alloys are aluminum, copper and magnesium. Zinc alloys can be divided into "deformed zinc alloys" and "cast zinc alloys" according to the processing technology. Cast zi
鋅合金錠是以純鋅為原料，依照國際標準或特殊要求添加其他元素，改善純鋅在鑄造性、化學性及物理性的不足而調配出來的合金。適用於鑄造並能使鑄件有好的表現。
