Copper and Copper Alloys

Because of its excellent physical, chemical and mechanical properties, it occupies an important position in many industrial and technical applications. They not only inherit the advantages of pure copper, but also improve some specific properties by adding other elements. The following is a detailed description of the unique advantages, production purposes, functions and applications of copper and copper alloys:

Unique Advantages:

Excellent electrical conductivity:

Copper is one of the best conductive materials after silver and is widely used in the electrical and electronics industry.

Good thermal conductivity:

High thermal conductivity makes it ideal for radiators, heating elements, etc.

Corrosion resistance:

Especially excellent in freshwater environments, suitable for water pipes, cooling systems, etc.

Machinability and weldability:

Easy to hot and cold processing, forming, welding and brazing, easy to manufacture complex shapes of products.

Beautiful appearance:

With good polishing and coating ability, suitable for decorative purposes.

Biological inhibition properties:

Copper and its alloys have a natural antibacterial effect on many microorganisms and can be used in public health facilities.

Needs met:

High-efficiency electrical transmission:

Such as power cables, bus bars, etc., where low-resistance materials are needed.

High-performance cooling solutions:

Computer CPU heat sinks, automotive radiators and other components that require good thermal conductivity.

Corrosion-resistant structural parts:

Equipment exposed to corrosive environments such as ship construction and seawater desalination equipment.

Precision mechanical parts:

Watch gears, precision instrument components, etc., need high precision and stability.

Architectural decoration:

Roof, exterior wall cladding panels and other applications that need to be both beautiful and durable.

Public health and safety:

Antibacterial treatment of frequent contact surfaces such as hospital doorknobs and elevator buttons.

Features
Electrical connection and transmission:	As a conductor on wires, cables, printed circuit boards, to ensure the effective transfer of current.
Thermal management and control:	Used to make radiators, heat exchangers, etc., to help maintain the operating temperature of the equipment.
Structural support and protection:	Provides strength while resisting environmental erosion and extending service life.
Decoration and artistic creation:	Through different surface treatment techniques to achieve a variety of visual effects to meet aesthetic needs.
Biomedical applications:	Use its antibacterial properties to make medical devices, implants, etc., to protect the health of patients.

Common fields:

Electrical and electronics industries:

Copper is used in almost all electricity-related products, from electrical wires for homes to transmission lines for large power plants.

Heating, ventilation and Air conditioning (HVAC) :

Critical components such as refrigerant piping, evaporators and condensers.

Architecture and infrastructure:

Roofing materials, curtain walls, window and door frames, etc., provide both functionality and beauty.

Automotive manufacturing:

Engine cooling system, brake system, electrical wiring, etc.

Marine engineering:

Ship shell, propeller shaft and other parts resistant to seawater corrosion.

Medical devices:

Surgical instruments, dental tools, etc., especially those requiring biocompatibility and anti-infection properties.

Communication network:

The copper shielding layer of the optical fiber communication system protects the signal from interference.

Instrument manufacturing:

Brass instruments such as trumpet, trombone, etc., are widely used because of their good sound quality characteristics.

Specific models and their features:

Pure copper (Cu-ETP, Cu-OFE) :

Has very high electrical and thermal conductivity, widely used in wire and cable manufacturing.

Brass:

Copper zinc alloy, according to the different zinc content is divided into a variety of types, such as 65/35 brass (containing 65% copper and 35% zinc), often used in decorative parts and mechanical parts.

Bronze:

Copper-tin alloy, known for its wear resistance and self-lubricity, suitable for friction pairs such as bearings and gears.

Nickel Silver:

A copper-nickel-zinc alloy that, despite its name, does not contain silver and is named for its proximity to silver in color and is often used in jewelry and ornaments.

Aluminum Bronze:

Copper aluminum alloy, with high strength and corrosion resistance, suitable for heavy loads and harsh environment applications.

Phosphor Bronze:

Copper-tin-phosphorus alloy with good elasticity and wear resistance, widely used in springs, connectors and other fields.
