Which is better, copper or zinc alloy hardware pendant?

Zinc alloy is a good choice, which is more durable than copper and more cost-effective than copper lamp. Those who make copper lamps say that copper lamps are good, and those who make zinc alloys say that zinc alloys are good. This is a pertinent answer. In fact, the quality is almost the same, and one material is expensive and cost-effective. If you are not pursuing precious metals, zinc alloy is a good choice.

Material: Zinc alloy is an inert metal, which will not rust or oxidize. High cost performance and wide application. Copper lamps are made of 60 or 65 alloy copper, not pure copper. Pure copper is too soft to make handicrafts. Alloy copper is easily oxidized to produce patina, such as bronze Buddha statue, with protective color on its surface. If it falls off, the patina will turn black. Zinc alloy has a silvery white surface and a protective color layer. So it is mainly the difference between the two technologies, mainly the price.

. Process: Zinc alloy is generally die-cast zinc alloy, and it will be polished after being made into blank, including fine polishing and rough polishing. There are many processes of color protection layer, generally electroplating and baking, because zinc alloy itself is inert, does not rust and does not oxidize. As long as the color protection layer is well done, there will be no problems for many years, and oxidation and discoloration are all surface color layers.

Copper lamps include copper tubes, sand-to-copper and dewaxed copper, and the blanks should be polished and coated with protective layers. However, alloy copper is easy to rust, and the blank will rust quickly after polishing, so it needs pickling before making the color layer, so it will oxidize and turn black soon if the process is not done well. Both materials should have protective colors. If the protective layer is oxidized and discolored, the copper inside will turn black or produce patina. The actual use is similar, the key depends on the surface technology. Relatively speaking, zinc alloy is more durable.

Maintenance: All lamps and lanterns should be maintained with dry rags, and don't get wet with detergent, because the surface is covered with a protective color, and there is no metal surface protective layer of lamps and lanterns in the world that can last for generations.

Value: Copper is more expensive than zinc alloy, and zinc alloy is cost-effective. I like that key. Look at your own needs. Whether it is collectible can be regarded as a handicraft, not because the material is collectible. If you want to collect it, you should mainly look at the artistic value of the style.
