Long Life-span Granted by Corrosion Resistance
Copper alloys are praised for their superb resistance to corrosion. This is due to the natural ability of copper to form a protective oxide layer on its surface when exposed to air, which acts as a barrier against corrosion. The addition of other elements to copper, such as tin, nickel and zinc, can further enhance the corrosion resistance of copper alloys.

 

High Conductivity, Satisfying Different Conditions
Apart from being in a long life span, copper alloys are also known for their high electrical conductivity, which is second only to silver. Copper alloys have a high number of free electrons that can move easily through the material, allowing electricity to flow with minimal resistance. This property makes copper alloys viable for electrical and electronic applications.

 

Strength Retention, Toughness and Brittleness
Copper alloys are well known for their excellent mechanical properties, including high strength, ductility and toughness. These properties make copper alloys a perfect material for a wide range of applications, particularly those that require reliable performance in demanding conditions.

 

Excellent Machinability and Ease of Fabrication
Copper alloys have excellent machinability due to their unique combination of properties, including their high thermal conductivity, low hardness and good ductility. These properties allow copper alloys to be easily machined, shaped and formed into complex parts and components.

 

Resistance to Biofouling and Repels Algae and Barnacles
Copper alloys have been found to be highly effective in preventing biofouling. The natural antimicrobial properties of copper, combined with its ability to form a protective oxide layer, make it a feasible material for marine applications. Copper alloys can effectively inhibit the growth of microorganisms, such as bacteria and algae, on their surfaces, reducing the buildup of biofouling and improving the performance and efficiency of marine structures.

Types of Copper Alloys

 

Brass

The brass family of copper alloys incorporates zinc and other metals in different ratios to enhance strength, ductility, conductivity, corrosion resistance, and machinability.

Tin Brass

Tin brass is a member of the brass alloy family that includes copper, up to 40% zinc, and up to 3% tin. This high-strength, exceptionally corrosion-resistant brass is ideal for use in naval and marine applications.

Silicon Red Brass

Silicone red brass is a type of brass with less than 20% zinc and up to 6% silicon. An exceptionally strong alloy, silicon red brass is used for fail-safe valve components, gears, and bearings that require high corrosion resistance.

Bronze

The bronze family of copper is composed of copper alloys blended with tin. Its strength, corrosion resistance, and attractive finish make it popular for marine, engineering, and architectural applications.

Phosphor Bronze

Small amounts of phosphorus enhance bronze’s fatigue and wear resistance, for a harder alloy ideal for high-pressure, high-tension applications such as springs, gears, bearings, shafts, and fasteners.

Aluminum Bronze

Aluminum bronze includes between 5% and 12% aluminum, along with various combinations of other metals. This produces alloys with superior strength, corrosion resistance, toughness, and wear resistance.

Silicon Bronze

Silicon bronze alloys incorporate 3% silicon and 1% manganese to enhance ductility, strength, and weldability. They are perfect for architectural applications that require both beauty and functionality.

Copper Nickel

Copper nickel alloys are a family of copper alloys engineered for optimal resistance to corrosion from seawater in marine environments.

Nickel Silver

Nickel silver is named for its pleasing silver color. It is made up of copper, zinc, and between 10% and 20% nickel, and it offers the same level of corrosion resistance and strength as other brasses.

 

Process Of Copper Alloy
 

Raw material selection

The first step in copper alloy production is the selection of raw materials. Usually, copper is combined with other metals to form alloys with specific properties. The quality of the raw materials used plays a crucial role in determining the final product's quality.

Melt

Next, the raw materials are melted in a furnace. The furnace is heated up to high temperatures, and the raw materials are added to the furnace in precise proportions. This phase is critical because the correct proportions of the metals are vital in determining the properties of the final product.

Forming

After melting, the molten alloy is poured into molds to form slabs or billets. These molds are made of sand, graphite, or stainless steel, depending on the final product's requirements. After cooling, the resulting products are heat-treated to improve their mechanical, electrical, and thermal properties.

Testing

The final phase in the production process is the testing and quality control phase. The products are subjected to various testing procedures to ensure that they meet the required specifications. This phase ensures that the final product is of the highest quality, and it meets the customers' requirements.

 

Packing & Shipping

 

All our Copper alloy products are packaged in accordance with international standards to prevent any possible damage or loss. By default, we use thick woven bags to bundle finished tubes in batches. For some special pipes and pipes that are susceptible to dirt, scratches, stress or rough handling, we recommend wooden box protection. Please note that wooden boxes will incur additional costs, not only for the box itself, but also for shipping costs, especially by air. To enhance the customer experience, we can also offer special packages based on your specific requirements.
