Brass Specialists

A gold glimmering metal
Brass is a versatile product. By adding various elements to its basic composition of copper and zinc, brass can be given unique characteristics. Different types of brass are suitable for different types of processing and finished products. At Nordic Brass Gusum, we manufacture brass rods, profiles and bars for further manufacturing by our customers. Screws, nuts, plumbing fixtures and fittings, lock parts, electrical components and decorative items are just some of the articles we produce. Brass is a reusable material and has a given place in environmentally friendly industrial production. It can be recycled profitabliy as approximately 80 percent of the raw material used comes from brass scrap, either returned from our customers, or from other recycling firms.

Anti-Corrosive Properties
Most brass alloys have good resistance to corrosion under normal conditions. However, special alloys must be used for certain applications, for example in plumbing fixtures where dezincification is required. Our Esmatur alloys are suitable for both turning and hot forging and fulfil regulatory requirements for plumbing fixtures and fittings in a number of countries.

Surface treatment
Brass has a golden, lustrous surface which can be polished to a brilliant finish. Sometimes, however, surface treatment is necessary to protect the surface or to achieve a certain appearance. Brass is easy to plate in a number of ways. Chroming of plumbing fixtures and fittings is one such example. Gilded decorative and utilitarian objects are also becoming more common.

Machining
The vast majority of brass we deliver is machined with cutting tools into the finished product. This type of brass normally includes lead because its chipping qualities and lubricating effect permit high machining speeds with minimal tool wear. Good machining characteristics facilitate high productivity and low production costs when compared to steel, for example. This, in combination with profitable recycling of machining chips, means that many brass articles can be produced more economically in brass than in steel.

Forging
Brass is easily worked by forging. Very high reduction degrees are possible and even intricate products can be formed to near-complete design with good surface finishes and close dimensional tolerances. Final processing can require machining, polishing or surface treatment depending on the application area. The plasticity of forming during the forging process gives brass a non-porous and, strengthwise, very favourable structure with high ductility and hardness.
