Brass wire

Brass wire in coil format for cold stamping.

Data sheet: Brass wire

At Bronmetal we supply CuZn brass wire in rolls for cold stamping.

Annealed, semi-hard and hard state.

Brass is obtained from the alloy of copper Cu + zinc Zn and it has different qualities/characteristics depending on the proportion of each metal involved. Meanwhile, other materials may be involved in its composition, leading to combinations adapted to different requirements.

Brass wire is an alloy composed mainly of copper and zinc and is widely used in various industrial applications due to its properties and characteristics. One of the most outstanding properties of brass is its high corrosion resistance, especially against salt water corrosion, which makes it ideal for marine applications and corrosive environments.

At Bronmetal we supply brass wire in two types of alloys: copper-zinc and copper-zinc-lead. The main advantage of adding lead to copper-zinc alloys is the significant improvement in machinability. Lead acts as an internal lubricant, reducing tool wear and allowing higher cutting speeds.
