The difference between annealed wire and galvanized wire
The main difference between annealed wire and galvanized wire lies in the processing technology and core performance. Annealed wire obtains flexibility through high-temperature annealing, while galvanized wire strengthens its anti-corrosion performance through surface galvanizing process.
Differences in production processes
Annealing wire: High temperature annealing is used to eliminate internal stress in materials, making the metal structure more uniform. This process reduces hardness and improves ductility.
Galvanized wire: A metal protective film is formed on the surface of iron wire by electroplating or hot-dip galvanizing, and the process includes steps such as acid washing and galvanizing, which have a small impact on the hardness of the base material.
Core performance comparison
Physical characteristics
Annealed wire: It has excellent flexibility and ductility, can be repeatedly bent without easily breaking, and has low residual stress.
Galvanized wire: retains high original strength, zinc layer enhances structural stability, suitable for load-bearing scenarios.
Protective performance
Annealing wire: prone to rusting, its service life is significantly affected by the environment, and it should be avoided in humid environments.
Galvanized wire: The thickness of the hot-dip galvanized layer can reach 50-300 μ m, and it can still remain rust free for 5-30 years when exposed to rainwater or salt spray.
Application scenario differentiation
Typical uses of annealed wire
Temporary tying of buildings: utilizing its soft properties to tightly wrap steel bars without damaging the surface.
Precision hardware products, such as jewelry welding and handicraft weaving, rely on their easy to form characteristics.
Typical uses of galvanized wire
Permanent outdoor facilities: power tower cables, marine aquaculture cages, relying on long-term anti-corrosion capabilities.
High strength structural components: scaffold connectors, mechanical springs, combined with strength and rust prevention requirements.
