1.什么是ZAMAK？锌压铸合金终极指南 |韦尔斯哈夫特 What Is Zamak? Zinc-based die casting alloys (ZAMAK, also known as ZAMAC) are widely used zinc alloys that have revolutionized high-pressure die casting since their introduction in the 1920s. In this Zamak Casting & Alloy Guide, Welleshaft, your trusted zinc die casting parts manufacturer, provides ZAMAK castings for various industries to meet the demand for strong and durable components. 2.什么是ZAMAK（或ZAMAC）？ ZAMAK是一种由锌、铝、镁和铜制成的锌合金，已形成德语首字母命名。它的耐压性能好，铸造过程光滑，是压铸的理想选择。 虽然通常拼写为ZAMAC，但它们是同一种材料。与ZA合金不同，它具有独特的用途——从电子外壳到ZAMAC钉扣，再到收藏级压铸造风火轮。 合金成分表 合金类型 锌 铝 镁 铜 暗示的属性 锌合金3 95% 4% 0.03% 0.02% 流量和强度的平衡 锌合金5 94% 4% 0.03% 1% 更高的强度；能有效处理管道腐蚀 锌合金2 96% 4% 0.03% 3% 坚固耐磨；高温作业 锌合金12 89% 10% 0.05% 1% 非常适合坚定的部件 易扎克 各系 更高 各系 各系 更适合爬行；适合加热装备 3. ZAMAK在压铸领域的历史 在这种合金出现之前，工厂使用廉价的“锅金属”，这种合金很容易熔化，但在压力下经常破裂。 这催生了一种更坚固、更可靠的锌基材料。如今，从建筑栓到锌压铸机制造的零部件，锌基材料的应用范围十分广泛。 4.为什么选择ZAMAK进行压铸？ （1 ）巩固而坚定 与塑料和较软的金属相比，这些锌合金成分不仅保持形状稳定，而且重量轻。我们进行了5比3的抗拉强度研究，揭示了威胁部件的最佳性能。 （2 […]

Does Zinc Die Cast Rust? 1.Does Zinc Alloy Rust Over Time? Choosing material for die cast metal parts means asking—does zinc alloy rust? People often worry about how parts hold up once they hit air, water, or chemicals. Welleshaft’s zinc alloy parts resist wear that steel can’t match—without turning into red rust. 2.What Is Zinc Alloy and What Is Die Cast Metal? （1）What Is Zinc Alloy Material? A zinc alloy mixes zinc with bits of aluminum, copper, magnesium. This mix gives it better grip, strength, and rust resistance. We see zinc used a lot in auto parts, jewelry, door fittings, and more. （2）What Is Diecast Metal? In diecasting, you push liquid […]
