7075 Aluminum Wire is a High Strength Alloy Used in Cold Heading Applications

Bob Martin Company wire manufactures cold heading wire to withstand heading, and forming with top-quality. The cold heading wire process includes molding wire into a specific shape without the need for heat. A piece of wire is pounded while inserted into a die, and the force of the hit causes the metal to pour into a restricted die cavity.

Extensively found throughout the manufacturing and construction industries, the cold forming process is an ideal solution for wire fastener and cold heading applications.

Cold Heading Benefits

Cold heading wire and cold forming have many benefits, including flexibility. Metal wire components can undergo the “one die, multiple blow” method where the part is hit multiple times while remaining in a single die. On the other hand, the metal wire components are progressively transferred from die to die.

We call this method multi-die forming. Additionally, cold forming is consistent and limits scrap. With the material flowing to fill the die cavity and dimensional tolerances defined by the tooling, there is little to no scraps leftover. The cold heading wire process delivers higher yields than other standard processes, reducing costs and increasing production.

Aluminum Wire Types

High productivity and efficient material mean significant cost and consistency advantages. The cold heading wire process increases the native tensile strength of the materials through work hardening. This cannot be achieved by other processes that remove materials from their native shape.
