Advantages of Copper Extrusions

 

 

 

High Electrical and Thermal Conductivity:
Copper excels at conducting both electricity and heat, making it ideal for electrical wiring, busbars, heat exchangers, and plumbing components.

 
 

Malleability and Ductility:
Copper is easily shaped and formed, allowing for complex shapes and profiles in applications like copper tubing and rods.

 
 

Surface Finish:
Extrusion creates a smooth, precise surface finish, enhancing the appearance and functionality of copper products.

 
 

Stronger Material:
Copper can be cold worked during extrusion, further increasing its strength and hardness, making it suitable for demanding applications.

 
 

Natural Antimicrobial Properties:
Copper has natural antimicrobial properties, making it a good choice for applications where hygiene is important.

 
 

Versatile and Adaptable:
Copper alloys can be easily fabricated and formed into a wide range of shapes and sizes, allowing for precise shaping and fabrication.

Architectural and construction
Manufacturers create products used in the building trade using castings, extrusions, forgings, hot rolling, stamping and other techniques. The lustrous shine of many copper alloys contributes to the popularity of decorative parts and accessories, such as plaques, glossy trim and door handles.

 

Electronics
The high electrical conductivity of copper makes copper and copper alloys vital to numerous electronic and consumer goods manufacturers. Copper wire can transmit an electrical charge better than many other types of metals, for instance.

 

Automotive
Automakers depend upon copper extrusions for many purposes, too. For instance, in addition to sophisticated electronic circuitry, modern automobiles often use decorative copper alloys in cabin decors.

 

Plumbing
Copper and copper alloys transmit thermal energy well. For this reason, they play a significant role in many plumbing systems.

 

Industrial
Industrial manufacturers rely on copper alloys and copper extrusions for numerous purposes. For example, copper-based finishes May cover some metal components. Copper alloys (including bronze) withstand many types of machining well.

 

Oil and gas
Copper and copper alloys help form pipes and tubing. The oil and natural gas industries use copper products widely.

 

Maritime
Some specialized types of copper alloys have gained popularity due to their resistance to corrosive marine environments. For example, naval bronzes and naval brasses frequently form fixtures and decor items aboard ships.

 

Telecommunications
Copper alloys and copper extrusions play an important role in telecommunications systems. From satellites to space exploration and mobile phone technology, copper alloys will likely remain important to human innovation in the telecommunications industry in the future!

 

Process of Copper Extrusions

Raw Materials
High-purity raw material in the form of copper is used. It is always in excess of 99.9% pure in content. This provides optimum performance both electrically and thermally.
Sometimes, amounts of an alloying element such as phosphorus, tin, or silver are added to enhance certain aspects such as strength or hardness.

 

 

Melting & Casting
The selected raw material in raw form is heated in an appropriate range of temperatures in a furnace. Melting point is around about 1083°C in most traditional copper alloys. Additions can be carried out in the process of melting to alter the qualities in the copper alloy. Liquid copper is poured in the form of billets upon heating.

Extrusion process

The billets get heated to an appropriate range between 600 to 800°C to gain increased ductility. The billets are placed in an extrusion press. Used is correctly shaped die with desired special-shape. Enormous amount of pressure is applied by the press to drive in heated copper billet through die to form special-shape extrusion.

Heat Treatment

After extrusion, these specially shaped copper extrusions can be processed by heating to achieve improved mechanical strength. One of the most commonly practiced processes to treat these is annealing. This is achieved by heating these extrusions to a certain point and then allowing these to gradually get cold. This process can soften internal stress, improved ductility, and improved conductance in these copper extrusions.

Finishing And Quality Assurance

The extrusions later go through various final processing including cutting to final sizes, deburring, and surface treating. Surface treating can be plating or coating to obtain added corrosion resisting qualities. Tests in accordance with requirements in respect to quality control including check in order to dimensional requirements, check in respect to surface requirements, and tests to determine physical requirements are carried out to check that special-shape copper extrusions obtain design requirements.

A: Yes, if it is the stock product, the sample can be sent for free in 3 days, if customized, will be sent within 7 days.

Q: How about the sample policy?

A: We can provide free sample. However, you have to pay the cost of courier by express like: DHL, TNT, UPS and FEDEX.

Q: Can you make my designs?

A: Yes, OEM/ODM is welcome, pls feel free to send us pictures. If necessary, we can keep your design be protected under law.

Q: How could I pay them?

A: Paypal, Western Union, T/T, L/C are acceptable, so just let us know which is convenient for you.

Q: Can I get discounts?

A: Yes, for big order, old customer and frequent customers, we give reasonable discounts.

Q: How long is the manufacturing lead time?

A: The delivery time is 15-30 days, depending on the product. We could make some special production arrangement effectively if customer has urgent need.

Q: What is copper extrusion?

A: It's a process where heated copper is forced through a die to create long, uniform shapes like bars, rods, and hollow profiles.

Q: What is the temperature of copper extrusion?

A: Hot copper extrusions are normally done between 600 and 1000˚C. Using temperatures above the dynamic recrystallization temperature results in a uniform fine grain structure in the final extrusion product.

Q: What are the three basic methods of extrusion?

A: There are three main methods of extrusion: direct, indirect, and hydrostatic. In direct extrusion, also known as forward extrusion, the metal billet is placed in a container and pushed by a ram through the die.

Q: What types of copper alloys can be extruded?

A: Pure copper, copper-nickel alloys, and high-copper alloys can be extruded.
