A6005C is an alloy developed in Japan, positioned between A6063 and A6061 in terms of strength. Its former name was 6N01, and it is characterized by high corrosion resistance, excellent extrudability, and superior weldability. Due to its ability to produce thin-walled and complex cross-sectional shapes, it is widely used in railway vehicles such as Shinkansen and subways. Its high extrudability allows for easy extrusion of large profiles, making it possible to reduce the number of weld joints.

A3003 is one of the representative alloys in the 3000 series, made by adding manganese to pure aluminum. It retains the corrosion resistance and good workability characteristic of pure aluminum while improving strength. As a non-heat-treatable alloy, it does not undergo aging treatment. Additionally, it is rarely used as a cutting material, which is another notable feature. Its main applications include electrical machinery parts and heat exchangers. Aluminum cans are also made using alloys from the 3000 series.

A1070 is made of pure aluminum material, with a purity of over 99.7%. As it is a pure aluminum material, it does not have elements added like other aluminum alloys to improve strength or extrudability, resulting in lower strength and a characteristic softness (ductility). Due to its high purity of over 99.7%, it has excellent corrosion resistance, as well as superior thermal conductivity and electrical conductivity. Therefore, A1070 is used in heat exchanger components, machine parts, and components related to power transmission and distribution. By the way, the last two digits of A1070, "70," indicate its purity, confirming that it has a purity of 99.7%. For example, A1100 indicates a purity of over 99%, while A1050 indicates a purity of over 99.5%.

A6063 is an aluminum alloy that adds magnesium and silicon to aluminum, and it is the most representative extrusion alloy among the 6000 series. It is characterized by high corrosion resistance and excellent workability. Additionally, A6063 has excellent extrudability, allowing for the precise extrusion of products with complex shapes. When welding is required, structural assembly using rivets or bolts is often performed. Therefore, A6063 is a highly versatile alloy, capable of extruding various shapes of products such as pipes and channels. Furthermore, due to its high extrudability, it is particularly widely used as material for the interior and exterior of buildings.

C4641 is also known as naval brass, which is a type of brass that has a small amount of tin (Sn) added to it. Due to the addition of tin, it has excellent hardness and strength, and its resistance to seawater is higher than that of regular brass. Therefore, it is used in ship parts and similar applications.

• Coastal construction

C2800 is suitable for super-large shapes due to its iron content being suppressed, and in terms of bendability, it is the best brass. It is suitable for bending processes both hot and cold. The mechanical properties include tensile strength and ductility, making it suitable for applications such as wiring devices used as punched or bent, nameplates, equipment parts, valve rods, condensate pipes, construction materials, and welding rods. *Valve rod: A rod that rotates the valve body (disk) to adjust the flow rate by turning the handle of a valve, etc. *Condensate pipe: A cooling pipe used in condensers that cools steam and returns it to water.

• Gates, walls and fences

It is easy to forge complex shapes, and the internal structure consists of dense metal crystals. The forged structure is sufficiently broken down by the extrusion process, resulting in metal flow along the forged surface, which gives it excellent mechanical properties. It is used in high-pressure valves, parts that require advanced mechanical properties, and rotor bars, among others.

• Power and Energy Equipment

C3604 is known as free-cutting brass type 2, and its composition enhances machinability by adding lead to brass, making it particularly excellent in machinability. Machinability refers to how easily a material can be machined, and free-cutting brass is characterized by its ease of machining, as its name suggests. It can be machined with minimal force, resulting in a smooth finished surface, and the chips produced are fine and easily separable. Additionally, it has excellent properties such as weldability and plating ability. The specific gravity is 8.5.

C2700 has good ductility and cold workability, and its strength increases with processing. It also has good bendability and drawability, making it widely used for complex processed products and deep-drawn items. Its features and applications include good electrical conductivity, making it suitable for electrical product components, and high thermal conductivity, which is used in heat exchangers, steam boilers, and cooler heat exchanger components in chemical plants. Additionally, due to its excellent ductility, it can be easily drawn and bent, making it suitable for everyday items such as electrical sockets, cosmetic cases, lighters, and hooks. Furthermore, it does not exhibit low-temperature brittleness, allowing it to be used even at ultra-low temperatures, and its beautiful golden color gives it aesthetic appeal for use in construction materials and various utensils.

• Parts and Materials

Brass rods are generally often machined from round, hexagonal, or square shapes. Special-shaped bars can be extruded or drawn into shapes that are close to the final form at the material stage. This can shorten manufacturing time and reduce costs for our customers. In addition to C3604, we also have our developed alloys KS-B, KS-R, and KS-H, which can achieve more complex shapes. We also handle materials that are not commonly available from other manufacturers, such as C2700, C2800, C3771, C4641, and C6782. Additionally, we offer environmentally friendly cadmium-free and lead-free materials. 1. While round bars are mainstream for copper products, there is room to consider special shapes as the product shape deviates from round bars. 2. By reducing the machined parts, material loss can be minimized. 3. The reduction of processing steps can shorten processing time. 4. Processing of the outer shape is unnecessary; finishing may only involve cutting in some cases. 5. Since long-length processing is difficult with machining, the longer the product length, the more cost advantages can be realized. There is also the potential to produce parts that cannot be made by machining due to their length. Please feel free to contact our sales representatives for more information.
