Badge customizationThere are many materials, such as copper, iron, stainless steel, alloy materials, gold and silver, so, how do we distinguish how to distinguish between copper alloy and copper badge?
1, the simplest way is. Wipe the face and look at the color. “, using a piece of fine sandpaper on the identification of the object used to sand, such as rose red is copper, other colors are different types of copper alloys. To determine the correct color, find a enameled wire or wire and sand it. It is copper, not copper alloy.
2, copper is composed of copper element alone, even if there are other metals, but also a very small amount of impurities exist. Copper alloy is different. It is an alloy composed of copper and other metals, such as copper zinc alloy for brass, copper tin alloy for bronze, copper with beryllium is beryllium bronze, copper aluminum iron alloy for aluminum iron bronze and so on.
3, the application of copper is generally conductive parts, such as convergence bar, wire and cable, enameled wire, etc. Copper alloys are used in a wide range of applications, from screws and nuts to waveguides, springs, reeds, early pull chains, lamps, lighting, and so on.
