We often say that zinc alloy is a kind of synthetic non-ferrous metal. Because it is not easily oxidized and durable, this material is the preferred material for high-grade craft products and the industry.

Key explanation:

The so-called zinc alloy is an alloy in which other elements are added based on zinc. The alloying elements usually added are aluminum, copper, magnesium, cadmium, lead, titanium, and the like.

Benefits: Zinc alloy has a low melting point, good activity, easy fusion welding, brazing and plastic processing, corrosion resistance in the atmosphere and easy recycling and remelting of residual waste;

However, the creep strength of zinc alloy is low. And it is prone to natural aging to cause dimensional changes. Prepared by melt, die-cast, or pressure processed into a material.

It can be divided into cast zinc alloy and deformed zinc alloy according to the manufacturing process. Among the zinc alloy components, the effective alloying elements: aluminum, copper, magnesium; the harmful impurity elements: lead, cadmium, tin, iron.

What kind of products are the zinc alloy made?

Zinc alloy material is one of the more high-quality materials used in the production of “lapel pins”. It is usually used to make custom lapel pins and medals with collection value and long-lasting preservation. “Sports commemoration custom pins, marathon commemoration medals, class reunion custom enamel pins, etc.”

Zinc alloy is an alloy made of zinc mixed with other materials. The color of zinc alloy is the same as that of silver. It is now widely used due to its strong plasticity. The material is often used as a keychain, custom lapel pins, medallion, commemorative coins, medals, and other metal crafts.

Since the product made with it is not rusted and wearable and a product can be used for a long time, so it can always be loved by people and the material of choice for the merchant.

Zinc alloy custom pins does not rust

The reason why zinc alloy does not rust is similar to that of its own automatic defense system. Because zinc is combined with oxygen molecules in the air, it will form a dense passivation film on the surface to prevent air from continuing to attack the interior of the metal matrix.  But the surface of the zinc alloy will be discolored after a long time. If the surface dust is removed, the inside is still the same as the original zinc alloy. No matter how the surface is eroded, it will not become something similar to rust.

In addition, the surface of the finished zinc alloy will be plated with a layer of metal.

The zinc alloy custom lapel pins are made by die-casting. The items produced are fine workmanship, the corners are distinct, the pattern text is clearly visible and the hardness is higher than other synthetic metals. It has good wear resistance, the casting surface is smooth, and the polishing is not easy to deform which can carry out a variety of surface treatments, such as plating, spraying, painting, and so on.

One thought on “Why Are Custom Lapel Pins Of Zinc Alloy Not Rusting?

  1. Hey,

    Dear we need to know what paint can you use for paint the lapel pins?? Or what are other supported paint???

    Also let us know what method you adopt for polishing the pins???
