Copper stamping uses the
deep drawn metal stamping process to form copper sheet metal with a punch and die. The copper is fed into the metal stamping press and progressively formed by a punch that stamps the metal into a die. Complex and even asymmetrical shapes can be created via deep drawn stamping, with copper and many other types of metals.
Manufacturers of Copper Stamping
- Trans-Matic Manufacturing Company: is a world leading manufacturer of deep drawn metal stampings, including copper stamping. Trans-Matic has over four decades of experience with metal stamping in a myriad of different metal types, and extensive knowledge of copper metal stamping in the creation of plumbing components as well as parts for many other industries.
Advantages of Copper Stampings
Copper is a preferred metal for stamped components that are exposed to the elements, or that are used to convey liquids. Copper is corrosion resistant, much like stainless steel, but is far less costly than stainless steel. Copper is preferred for many plumbing-related applications as well as for temperature sensing components. While copper is corrosion resistant, it does tarnish quickly and very obviously. Copper left exposed to the elements quickly turns a green color -- this can often be seen on the roofs of old churches and other buildings. In some structural instances this tarnishing effect of copper is considered attractive and desirable, but for most metal stamping components it is not a benefit. When polished copper stampings can be exceedingly attractive; however, they will require a coating to prevent tarnish. While copper stampings can be more cost effective than stainless steel stampings and has advantages over stainless steel when it comes to brazing and soldering, copper remains a relatively costly metal. Copper stampings can be many times the cost of low carbon steel stampings. Furthermore, the scrap value of copper is so high that security becomes a concern: it's increasingly common to see property damage with the intent of stealing copper components for resale as scrap.
