Extruded Copper Profiles

Overview of Copper Extrusion

Copper extrusion is the solid straight strip with a particular cross-sectional shape and size after plastic processing materials with specific strength and toughness. Special-shaped copper bars are about conventional copper bars. The cross-sectional form is not square or rectangle-shaped. There are various shapes, such as “L” type, “T” type, trapezoidal type, and multilateral polygonal type. Most of them are based on the manufacturer’s specific product design requirements.

Advantages of Copper Extrusion

Copper extrusions have great electric conductivity, thermal conductivity, deterioration resistance and processability, smooth surface area without cord illustration, exact dimension, high mechanical homes, high copper web content, reduced oxygen web content, thick framework, and cost-free supply size.

The surface of the copper profile has a layer of oxidation-resistant, corrosion-resistant copper layer, which can maintain a stable structure during application and is not easy to corrode.

Mechanical properties and good properties: copper extrusions have good mechanical properties and sound properties, which can meet the needs of different applications.

Price stability: the price of copper extrusions is determined by the market, the market reflects the value of copper extrusions as tangible goods-related services. Copper on the market can bring significant benefits to people’s lives, and its service costs have become more apparent, so the price has become more reasonable.

Item	Characteristic	Fields of application
C11000	It has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazing. Impurities containing reduced electrical and thermal conductivity are small, and trace amounts of oxygen have little effect on electrical conductivity, thermal conductivity and processing properties, but it is easy to cause “hydrogen disease”, and it is not easy to process (annealing, welding, etc.) and use in a high temperature (such as 370 °C) reducing atmosphere.	Used in electrical, thermally conductive and corrosion-resistant equipment. Such as: wires, cables, conductive screws, detonators for blasting, chemical evaporators, storage devices and various pipelines
C10200、C10300	It has high purity, excellent electrical and thermal conductivity, no “hydrogen disease” or very little “ammonia disease” (no hydrogen embrittlement), good processing performance and welding, corrosion resistance and cold resistance	It is mainly used as electric vacuum instrumentation devices, various hardware products, lamps, pipe fittings, zippers, plaques, rivets, springs, settlement filters, etc
C12000	Its welding performance and cold bending performance are good, generally no “hydrogen disease” tendency, can be processed and used in a reducing atmosphere, but not suitable for processing and use in an oxidizing atmosphere. The residual phosphorus content of C12000 is less than that of C12200, so its electrical and thermal conductivity is higher than that of C12200.	It is mainly used in pipes, but can also be supplied as plates, strips or rods and wires. Used as gasoline or gas transmission pipes, drain pipes, condensation pipes, mine pipes, condensers, evaporators, heat exchangers, train car parts.

Production Method of Copper Extrusion

1. Raw Material Preparation High-purity copper ingots are selected as the starting material. These ingots are first inspected for quality, and any impurities are removed. The copper may be alloyed with small amounts of other elements like zinc or tin to enhance specific properties, depending on the application requirements.
2. Heating： The prepared copper billets are heated in a furnace. The heating temperature is carefully controlled, usually in the range of 600 – 900°C, depending on the copper alloy composition. This heating softens the copper, making it easier to extrude.
3. Extrusion： The heated billet is placed into an extruder. The extruder uses a powerful hydraulic press to push the billet through a die. The die has a pre-designed orifice shape, which imparts the desired cross-sectional shape to the copper as it is forced through, such as round, square, or complex profiles. The extrusion speed is also regulated to ensure uniform quality.
4. Cooling and Straightening： After extrusion, the hot copper product is rapidly cooled, often by water quenching. This helps to fix its shape and improve its mechanical properties. Subsequently, it is passed through straightening machines to correct any bends or deformations that may have occurred during the extrusion process.

Answer: The care and maintenance of copper extruded materials mainly includes regular cleaning, moisture-proofing and anti-corrosion, and avoiding mechanical damage. During use, avoid contact with sharp objects to prevent scratches, and keep its surface dry to prevent corrosion. For copper extrusions that have been exposed to moisture for a long time, anti-rust oil or plastic spraying can be applied to prevent oxidation.

Q5

Can copper extrusions be recycled and reused?

Answer: Yes, copper extrusions can be recycled and reused. Scrap copper extruded materials can be processed through processes such as smelting and refining to remove impurities and oxides to obtain pure copper liquid, which can then be re-extruded into new copper extruded materials. Recycling and reusing copper extruded materials is not only beneficial to resource conservation and environmental protection, but also reduces production costs.
