The main difference is carbon content. Iron has a carbon content of 2.11 percent or more, while steel has a carbon content of 2.11 percent or less. Iron-carbon alloys with carbon content of more than 2.11% are cast iron (pig iron), which are basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different, and the content of harmful impurities such as sulfur and phosphorus in steel is smaller. Wire general color key, wire color light point, white point.

In our daily life, what we can bend with our hands is basically galvanized iron wire, not steel wire. It has a high zinc content, which ensures excellent toughness and resilience, as well as ultra-high corrosion resistance, which can be maintained in outdoor environments for decades. There are many practical galvanized iron wire, such as strong reliability, galvanized layer and iron together, forming a special metallurgical structure, in the use and transportation process, can ensure that it will not be mechanical damage.
