Types of wire and properties of each type

1. Steel Wire
   Steel wire is a wire made from steel or carbon steel. It is highly strong, durable, and has many grades depending on the amount of carbon mixed in it.
2. Copper Wire
   Copper wire has excellent electrical conductivity, is highly tough and flexible.
3. Aluminum Wire
   Aluminum wire is lightweight, resistant to corrosion, and conducts electricity to a certain extent. Although not as good as copper, it is cheaper.
4. Lead Wire
   Lead wire is a wire with high flexibility, high density, and corrosion resistance.
5. Nickel Wire
   Nickel wire has high heat and corrosion resistance.

Factors affecting prices

1. Raw material costs
   Prices of metals used to produce wire, such as iron ore, copper and aluminum.
2. Energy costs
   Wire production is energy-intensive, especially for rolling and plating.
3. Supply and demand
   Demand for wire from major industries, such as construction and automotive.
4. Exchange rates
   Some materials must be imported and may be affected by currency values.
5. Government policies
   Import-export tax measures related to metal raw materials.
