Metal buttons are one of the most popular buttons. Their surface is smooth, durable and decorative. The materials used to make metal buttons are also different, which are generally divided into the following materials:
Zinc alloy button
Yellow Tung skin button
Stainless steel button
Aluminum button
Iron button
Zinc alloy buttons and brass buttons are generally common in the market.
Stainless steel buttons are also popular because they are less sensitive to rust and cost much less than zinc alloy buttons and brass buttons. In recent years, with the rising prices of alloy and brass materials, stainless steel buttons have also begun to occupy a place in the clothing button market.
There are also aluminum buttons that can achieve special effects on the market, especially in cloth buttons, which are widely used because their softness is not easy to damage the fabric, and even better than brass.
Iron buttons are less used in the market. Its biggest disadvantage is that its surface is easy to rust and corrosion, and the product cannot pass the needle test.
Now let’s take a closer look at the two most commonly used metal buttons, namely zinc alloy buttons and brass buttons.
Zinc alloy button
It is recognized as a kind of high-end metal buttons. Zinc alloy buttons are often used in high-end jeans, coats, uniforms, etc. It is also the most expensive metal button. However, the quality of the goods is much better if you pay for them.
Zinc alloy buttons are usually made of 5# zinc alloy, mainly composed of zinc and aluminum. These buttons will be polished after the die-casting process, which will remove burrs along the edge of the button or in the hole, and the rough surface will be treated before the electroplating process.
Brass button
It is considered to be another kind of high-end metal buttons. Brass buttons are usually used in jeans, casual wear, coats, handbags, etc. It is cheaper than zinc alloy buttons and more expensive than stainless steel buttons.
Brass is a metal alloy composed of copper and zinc. Brass buttons can be made of H62 copper, H65 copper and H68 copper. The main difference is the content of copper. The higher the content of copper, the easier it is to pass the needle detection with higher requirements.
How to distinguish zinc alloy buttons from brass buttons?
Zinc alloy buttons are heavy. In addition, you can use a hard object to scratch the electroplating layer of zinc alloy buttons / brass buttons, and observe the color of raw materials. Zinc alloy buttons look like iron in appearance. They are whiter, while brass buttons are golden.
