Data sheet: Brass bars

Bronmetal supplies brass bars in two types of alloys: copper-zinc-lead and complex copper-zinc alloys for improved properties. This type of product is designed for bar turning and hot stamping applications because they offer good wear and fatigue resistance – suitable for parts subjected to friction and repetitive movements. In addition, brass is a material with good ductility and malleability and a high resistance to corrosion, especially salt water.

Brass bar is used as a starting material in bar turning because, due to its composition, it is easy to handle and form. It is therefore an ideal material for the production of complex and detailed parts. Brass is characterised by its machinability, corrosion resistance and excellent thermal and electrical conductivity.
