What Is Copper?
Copper is a naturally occurring metal known for its excellent electrical conductivity, thermal performance, corrosion resistance, and durability. Industries worldwide use pure copper in electrical wiring, construction, automotive manufacturing, industrial machinery, and renewable energy systems.
As a versatile industrial material, copper is available in several grades, including electrolytic tough pitch (ETP), oxygen-free copper (OFHC), and deoxidized high phosphorus (DHP) copper. Each grade offers different properties for specific manufacturing applications.

Manufacturers use it to produce electrical conductors, copper wires, busbars, sheets, tubes, and other industrial components.
Properties of Pure Copper
Excellent electrical and thermal conductivity
High ductility and malleability
Good corrosion resistance in many environments
Excellent recyclability
Suitable for forming and fabrication
Long service life in appropriate applications
Applications of Pure Copper
Pure copper serves electrical transmission, power distribution, telecommunications, industrial machinery, and building infrastructure.
Manufacturers also use copper in renewable energy equipment, including solar installations, wind turbines, and electrical distribution systems.
Electrolytic Tough Pitch Copper (ETP)
Electrolytic Tough Pitch Copper, commonly identified as C11000, is one of the most widely used commercial copper grades.
ETP copper typically contains at least 99.90% copper, including silver, and offers excellent electrical conductivity.

Industries use oxygen-free copper in specialized electrical equipment, vacuum systems, electronics, semiconductor equipment, and high-performance conductors.
Deoxidized High Phosphorus Copper (DHP)
DHP copper, commonly identified as C12200, contains a controlled amount of phosphorus that reduces oxygen-related problems during manufacturing.
This grade provides excellent formability, brazing characteristics, and corrosion resistance.
Applications of DHP Copper
DHP copper is widely used in:
Plumbing tubes and fittings
HVAC systems
Heat exchangers
Refrigeration equipment
Industrial piping
Water distribution systems
Its combination of formability and joining performance makes it suitable for many tube manufacturing applications.
Copper Alloys and Their Properties
Manufacturers combine copper with other metals to produce alloys with specialized mechanical and chemical properties.
Copper alloys offer different combinations of strength, corrosion resistance, machinability, and conductivity.
Brass: Copper-Zinc Alloy
Brass contains copper and zinc in proportions that vary according to the required properties.
Manufacturers use brass in plumbing fittings, electrical connectors, valves, decorative components, and precision machinery.
Common advantages include good machinability, formability, and corrosion resistance in suitable environments.
Bronze: Copper-Tin Alloy
Traditional bronze primarily combines copper and tin, although the broader bronze family includes other copper-based alloys.
Bronze offers good wear resistance, strength, and durability.
Typical applications include bearings, bushings, gears, marine fittings, sculptures, and industrial components.
Cupronickel: Copper-Nickel Alloy
Cupronickel combines copper and nickel to provide excellent corrosion resistance, particularly in seawater environments.
Common compositions include 90/10 and 70/30 copper-nickel alloys.
Industries use these materials in marine piping, heat exchangers, desalination equipment, and seawater cooling systems.
Beryllium Copper
Beryllium copper combines copper with a small amount of beryllium to achieve high strength, hardness, and fatigue resistance.
Manufacturers use this alloy in springs, electrical contacts, precision tools, and specialized industrial components.
Processing operations must follow appropriate safety controls because beryllium-containing dust and fumes can create serious health hazards.
Aluminium Bronze
Aluminium bronze contains copper and aluminium, sometimes with additional alloying elements.
It offers excellent wear resistance, mechanical strength, and corrosion resistance in selected marine and industrial environments.
Common applications include marine propellers, pump components, valves, bearings, and heavy machinery.
Tellurium Copper
Tellurium copper typically contains a small amount of tellurium to improve machinability while retaining useful electrical conductivity.
Manufacturers select this alloy for precision electrical connectors, machined components, and specialized industrial parts.
