The difference between cold drawn wire and annealed wire
Cold drawn wire and annealed wire are two common metal materials that differ in production processes, physical properties, and usage scenarios. Below, we will provide a detailed explanation on how to distinguish between cold drawn wire and annealed wire from these three aspects.
1、 Production process
Cold drawn wire is steel wire produced through cold drawing process. This process mainly uses drawing to gradually thin the thicker steel wire through a mold, thereby obtaining the desired fine steel wire. During this process, the microstructure of the steel wire will become more compact, and its strength and hardness will also be improved.
Annealed wire is steel wire that has undergone annealing treatment. Annealing is a heat treatment process that involves heating steel wire to a certain temperature and then slowly cooling it to change its internal structure, reduce hardness, and improve plasticity. This treatment can make the steel wire softer, easier to process and use.
2、 Physical characteristics
Due to different production processes, cold drawn wire and annealed wire also have differences in physical properties. Cold drawn wire has high strength and hardness, as well as good wear resistance and tensile strength. This makes it perform well in situations where it needs to withstand high tensile and frictional forces.
In contrast, annealed wire has lower hardness and strength, but has good plasticity and toughness. It is easier to process into various shapes and less prone to breakage during use. This material performs excellently in applications that require flexibility and durability.
3、 Usage scenarios
Cold drawn wire, due to its high strength and hardness, is commonly used to manufacture parts and tools that require heavy loads, such as springs, steel wire ropes, etc. In addition, in the construction industry, cold drawn wire is often used as reinforcement for concrete structures to improve the stability and load-bearing capacity of buildings.
Annealed silk is widely used in the production of various handicrafts, woven fabrics, and daily necessities. Due to its excellent plasticity and toughness, annealed wire can be easily molded into various shapes and patterns to meet different design needs. At the same time, it is also used to make products that require flexibility and durability, such as mesh bags, hangers, etc.
