The material of belt buckle is divided into brass, copper, stainless steel, zinc alloy. Among them, the buckle made of zinc alloy is the vast majority on the market. It is not how good the zinc alloy is, but it is cheap enough and has a low melting point (385 degrees Celsius). It is easy to shape and can be made in various styles. The cost of the buckle is about USD6.18 for stainless steel, about USD6.18 for copper, about USD3.86 for brass, and as low as USD 0.31 and not more than USD1.55 for zinc alloy. So how to distinguish the material? Basically, it is difficult to have no experience. Brass, copper, and stainless steel have obvious characteristics, but it is difficult for zinc alloys. Because they can imitate various textures, most of the zinc alloy buckles are not their original colors. Use them directly. It’s ugly. And it is easy to oxidize. It is not corrosion-resistant. What we can see on the market is electroplated with a layer of corrosion-resistant metal such as chromium or copper. If you see brass or stainless steel, most of it is zinc alloy for chrome-plated or copper-plated products, if the coating is worn out, the zinc alloy will quickly undergo an electrolytic reaction, and the surface will bubble. Basically, this buckle will break soon. I actually want to tell everyone that most of the belt buckles you can buy on the market are only zinc alloy electroplated, red copper buckle. Most of businesses are unwilling to use it, even if it is used by many people, they can’t see it. Because the cost is high.
