Brass

Brass is an alloy of copper and zinc. It has been used since ancient time in decorative crafts because of its rich color. Typically, the copper content of brass ranges between 60% - 70% in components used in the lighting industry. The higher the copper content the warmer and more gold-like will be the brass. There are various methods for forming parts from brass and numerous finishes that can be applied to capture the richness of this outstanding alloy.

 
Forming Techniques
Extruded Brass

Brass may be pushed through a flat steel plate in the same manner as pasta is extruded through a pasta machine. Almost all brass tubing is produced in this manner. Extruded brass has a small amount of Iead mixed into the copper and zinc alloy to ease its flow through the extrusion machine.

   
Forged Brass

A stamping process in which brass sheet or ingot is heated to a plastic state (between solid and liquid) and then stamped to final size. The process produces extremely high quality and density. It is used especially for components with a broad smooth surface where there is no opportunity to camouflage even the slightest imperfection.

   
Sheet Brass

Sezanne uses sheet brass that is 70% copper and 30% zinc alloy, which "is most often supplied on coils. This exact combination makes for a rich finish that polishes to a most beautiful luster.

When our brass components are formed, either by stamping or by spinning on a lathe, we heat-treat the components to a temperature of 850 °F taking several hours. This heat treatment removes all of the internal stress in the brass so that the components will not fracture over a period of time. Many products on the market are made of alloys with lower copper content and are not heat treated for stress relief. These fixtures may fracture in time.
