Temper is designated in standards either by the letter h representing a minimum hardness or the letter r representing a minimum tensile strength.
June 10 2020 coppers c10100 c15999 are alloys registered with the u s.
We specialize in bronze brass and copper.
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.
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.
At basic copper we sell pure copper c110 other alloys and tempers available upon request.

Fr stands for flame retardant and does not denote that the material complies with the standard ul94v 0 unless testing is performed to ul 94 vertical flame testing in.
These alloys are stocked in various shapes including bar tube plate and sheet.
It also comes in many alloys that blend other metals with copper.
The primary mechanical properties of copper hardness strength and ductility determine its condition.
Fr 4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant self extinguishing.
Copper plate and sheet offer excellent dimensional control and high crack resistance which make these materials easy to cut machine and otherwise form.
