Exploring Trafilerie di Malavedo's copper-plated steel wire: soft vs. hard drawn

A prominent name in the wire-drawing world is Trafilerie di Malavedo, a company that has solidified its position as a leading figure in the industry, thanks to its decades of experience. The products offered by this historic Italy-based industrial business include hard-drawn iron wire, white annealed iron wire, copper-plated wire, galvanized iron wire, phosphated wire, pickled wire, and wire for screws, small metal parts, and special processing.

In this article, we will take a detailed look at the characteristics and applications of the copper-plated steel wire produced by Trafilerie di Malavedo. We will focus on the two main variants, namely copper-plated hard drawn steel wire and copper-plated soft steel wire. Each serves specific functions and finds applications in diverse industries owing to its unique characteristics.

Let's start with the basics, how is copper-plated steel wire manufactured?

 
The crucial step that imparts distinctive characteristics to the wire is copper plating. During this phase, steel wire is coated with a copper layer, which significantly enhances its electrical conductivity and improves the wire's adhesion to other materials, such as chrome. There are various methods for applying this copper surface layer, with the most common being immersion plating, which involves immersing the wire in a bath containing a solution of molten copper. Another widely employed process is copper electroplating, a process that utilizes an electrolyte solution containing copper ions. By applying an electric current to the wire, copper is deposited electrochemically onto its surface.

Copper-plated hard drawn steel wire: strength and durability

Copper-plated hard drawn steel wire is renowned for its exceptional strength and durability. Its inherent hardness, preserved during production, makes it well-suited for applications requiring substantial tightening force. For instance, it is used in the manufacturing of bolts and screws for industrial and automotive applications, where robustness and longevity are essential. Its hardness makes it ideal for withstanding torsion and compression forces, ensuring the integrity of connections.

Applications:
Automotive Industry: high-strength bolts, screws, and fastening systems.
Construction: structural connecting elements such as nuts and threaded rods.
Tool Production: hand tool manufacturing, such as wrenches and hex keys.

Copper-plated soft steel wire: flexibility and adaptability

In contrast, copper-plated soft steel wire is known for its flexibility and adaptability. It is extensively used in the production of springs, hooks, snap rings, and other components that require the ability to bend and adapt without compromising integrity. This feature makes it valuable in applications where the absorption of impacts, oscillations, or variable movements is required.

Applications:
Aerospace sector: springs and elastic elements for aeronautical equipment.
Electronics: connectors and flexible contact devices.
Industrial automation: components for handling and transport systems.

Copper-plated steel wire, with its two variants, represents a versatile material in the production of metal components, screws, and many other products. Trafilerie di Malavedo can provide it in diameters ranging from 0.5 to 10 mm.

All products manufactured by the company are the result of a careful selection of raw materials, established through strong partnerships with reliable suppliers. This commitment to sourcing excellence ensures top-notch quality standards. Regarding packaging options, a variety of formats to accommodate different specific needs are available, including coils, spools, bobbins, and reels.
