Processes
We use wire rod from internationally certified suppliers, carefully selecting carbon contents ranging from 0.04% to 0.88% and diameters between 5.5 mm and 17 mm.
The initial diameter and carbon content of the raw material are key factors in determining the final properties of the drawn wire, influencing its malleability, strength, and durability.
Heat treatments, surface treatments
Heat treatments include processes such as:
- Patenting: provides high strength and good ductility, ideal for small-diameter wires and products subjected to repeated cycles.
- Annealing: increases malleability and facilitates subsequent processes such as drawing and cold forming.
