Flakes used as insulation for liquid fuels. Whiskers used in thermal and electrical composites.、In works of art、manufacture of bronzes、brass、other copper alloys、electrical conductors、ammunition、copper salts、In a statistical analyses of the copper、brass and bronze industry、there are five primary markets: (1) building construction (41%)、including building wiring、and heating、air conditioning (qv) and commercial refrigeration、builders' hardware、and architectural materials、(2) electrical and electronic products (23%)、for example power utilities、telecommunications、business electronics and lighting and wiring devices、(3) industrial machinery and equipment、(14%) such as in-plant equipment、industrial valves and fittings、nonelectrical instruments、off-highway vehicles、and heat exchangers、(4) transportation equipment (12%)、including automobiles、trucks and buses、railroads、marine vehicles、aircraft、and aerospace vehicles、and consumer and general products (10%)、such as appliances、cord sets、ordnance、consumer electronics、fasteners、coinage、utensils and cutlery、and miscellaneous items.、For more Uses (Complete) data for COPPER、ELEMENTAL (10 total)、please visit the HSDB record page.、Synthetic Polymer MALDI Matrix Compounds、Substance listed with specific concentration in tattoo ink and、or permanent make up according to EU Commission Regulation 2020、2081. The concentration limit (by weight) is 0.025%.、Copper is used as a thermal conductor、an electrical conductor、a building material、and a constituent of various metal alloys such as brass and bronze. Copper compounds have been widely used historically as pigments in decorative art. Copper compounds are also commonly used in agriculture to treat plant diseases like mildew、for water treatment、and as preservatives for wood、leather、and fabrics.
