Cold-drawn bars from voestalpine Wire Technology are used when dimensional accuracy, straightness, and surface quality must be precisely defined. The fully integrated process chain from ore to finished rod enables consistent and reproducible properties in the range of a few hundredths of a millimeter.
This makes the bars particularly suitable for highly stressed components, tight tolerances, demanding forming processes, and components that undergo subsequent machining. Thanks to the controlled process steps and the coordinated material condition, cold-drawn bars are a suitable starting material for functionally and safety-relevant applications where tolerances, surfaces, and mechanical properties are crucial.

FAQ: Frequently asked questions about cold-drawn bars
-
A cold-drawn bar is a solid long product that is brought to its final dimensions through controlled cold forming. This process results in tight tolerances, high straightness, defined surface qualities, and stable mechanical properties.
-
The basic forming mechanism is similar, but the bar differs in terms of its geometry, larger cross-section, mass, and the associated higher requirements for dimensional accuracy and surface quality. These differences have a significant impact on tool geometry, friction conditions, and the entire drawing process.
-
Tighter dimensional tolerances, better surface quality, higher strength.
-
Yes, the development process is fully supported - from the initial idea to series production.
-
Often within a few weeks thanks to integrated research and production.
-
The material, degree of forming, and heat treatment must be precisely coordinated. Depending on the application, different requirements are paramount, such as strength, toughness, machinability, or surface cleanliness. A broad material portfolio allows a wide variety of properties to be specifically realized.
