Copper sheet material properties.
We specialize in bronze brass and copper.
Fr 4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant self extinguishing.
Applications for copper plate copper sheet copper sheet and plate offer unique properties noted above that make them useful in a wide range of applications.
Copper sheets can also be hammered tooled or embossed for added texture and decorative or functional appeal and come in many thicknesses from very thin copper foil to thick copper plate.

Types of copper and properties.
Mechanical properties of copper.
It is a soft malleable and ductile metal with very high thermal and electrical conductivity a freshly exposed surface of pure copper has a pinkish orange color copper is used as a conductor of heat and electricity as a building material and as a constituent of various metal alloys such as sterling.
These alloys are stocked in various shapes including bar tube plate and sheet.
Your complete source for bronze brass and copper alloys.
Copper plate and sheet offer excellent dimensional control and high crack resistance which make these materials easy to cut machine and otherwise form.
It also comes in many alloys that blend other metals with copper.
At basic copper we sell pure copper c110 other alloys and tempers available upon request.
Temper is designated in standards either by the letter h representing a minimum hardness or the letter r representing a minimum tensile strength.
