Although we deal with various types of buttons every day, many people do not know what kind of materials they have in each of these styles and colors. Let's learn together how to distinguish the material of these different types of buttons.
In our common types of buttons, materials can be roughly classified into three types: plastics (resins, plastics), metal buttons (copper, iron, alloys) and natural types (shells, wood, coconut shells, bamboo). The process of making buttons varies from material to material, and although some molded products look the same, the fact is that their materials are fundamentally different, and so their properties are different.
Plastic buttons and resin buttons are similar in appearance. Plastic buttons are formed by die-casting. Usually there is a line at the edge. Some manufacturers for the sake of beauty, will remove this line in the subsequent processing, the quality of such buttons will be slightly lighter than the resin. The resin buttons are mostly made of mechanical carvings. After the polishing process, they will look quite smooth. The surface of the resin buttons is easily scratched and easily softened in boiling water.
Copper buttons and iron buttons are metal buttons. To distinguish between these two materials, one can use a magnet to know. Some hard objects can also be used to scrape off the surface plating. The inside of copper shows gold, and the iron buckle shows black. There is also an alloy button, which is made by die-casting. The surface will be polished and polished.
