introduction
Zinc Metal for Galvanization
Zinc is corrosion-resistant and used in galvanization, alloys, and electroplating. Vital for human health, it's in batteries and sunscreens, and acts as a catalyst in certain chemical reactions.
Zinc, a corrosion-resistant metal, is valued for coating and protecting other metals in galvanization. It forms alloys like brass and is widely used in electroplating processes, enhancing corrosion resistance. Essential for the human body, zinc supports immunity and wound healing. Used in batteries, die casting, and agriculture (as a plant micronutrient), zinc is also found in sunscreen and cosmetics. Though beneficial, DEK ensures responsible handling in both industrial and biological applications because we consider its potential environmental impact and health considerations. In manufacturing, complex components are initially die-cast from zinc alloys and then undergo CNC machining for critical features.

TECHNOLOGY OVERVIEW
Basic Knowledge of Zinc
What is Zinc?
Zinc is a metal in Group 12 of the periodic table, which is widely used commercially. In the Earth's crust, it's a bit more abundant than copper and occurs mainly as the mineral sphalerite. China, Australia, and Peru are the leading producers. Zinc's major uses include preventing corrosion by coating iron and steel (galvanizing) and making alloys like brass. Galvanizing can be done through hot dip or electrogalvanizing. The former involves dipping steel into molten zinc, while the latter uses electrolysis to deposit zinc on steel strips.
In the human body, zinc is essential, concentrated in red blood cells, playing a role in enzyme carbonic anhydrase and insulin storage. Zinc is also important in plant health. The metal is obtained by roasting zinc sulfide ores and then either leaching or smelting. Zinc is also a component in electric dry cell batteries, and alloys with aluminum have lower melting points and good mechanical properties. Zinc's appearance changes over time due to oxidation. It has different isotopes, with 64Zn being the most common.

FAQ
Machining Zinc Buying FAQ
Yes, zinc can tarnish over time when exposed to air. This tarnishing process forms a thin layer of zinc oxide on the surface, which can give the metal a dull appearance. However, some surface treatments or coatings can be applied to reduce tarnishing.
Zinc is generally safe for jewelry but may not be as commonly used as precious metals like gold or silver. Some people may develop skin reactions to zinc, such as minor irritation or discoloration, particularly if they have sensitivities to certain metals. Using a protective coating on zinc jewelry is advisable to minimize skin contact.
Yes, zinc has antibacterial properties. It has antimicrobial activity and is often used in various applications, including coatings for surfaces with potential bacterial exposure. Zinc's antibacterial properties can help inhibit the growth of certain bacteria.
While zinc does have antibacterial properties, it is not an absolute barrier to all types of bacteria. The effectiveness of zinc in preventing bacterial growth can vary depending on the specific type of bacteria and environmental conditions. In some cases, certain bacteria may still survive on zinc surfaces, but their growth may be inhibited compared to other materials.
