Different Material Options at Be-Cu Inc.

In the dynamic and challenging marine environment, where components are constantly exposed to the corrosive forces of saltwater, the selection of appropriate materials becomes paramount. To ensure the longevity and reliability of marine systems, our company specializes in working with a diverse range of corrosion-resistant materials. These materials are carefully chosen to withstand the harsh conditions, maintain structural integrity, and contribute to the overall efficiency of marine operations. Below is an overview of the corrosion-resistant materials we excel in working with:


Stainless (Austenitic, Duplex, Super Duplex)

Stainless steel is a staple in marine engineering due to its exceptional corrosion resistance and mechanical properties. Austenitic stainless steel (e.g., 316L) is widely used for its excellent general corrosion resistance. Duplex and super duplex stainless steels provide enhanced strength and resistance to pitting and crevice corrosion, making them ideal for critical components like propeller shafts and valves.

Aluminum (5000 and 6000 Series)

Aluminum alloys are favored for their lightweight nature and high corrosion resistance in marine environments. The 5000 series (e.g., 5083, 5086) offers good strength and formability, while the 6000 series (e.g., 6061, 6063) is known for its excellent extrudability, making it suitable for structural components.

Copper-Nickel Alloys (90/10, 70/30)

Copper-nickel alloys strike a balance between corrosion resistance and biofouling resistance. They are commonly used for seawater system components like heat exchangers, condensers, and piping due to their resistance to both marine corrosion and bacterial attachment.

Titanium Alloys

Titanium boasts exceptional resistance to corrosion in seawater, making it ideal for critical marine components. Its high strength-to-weight ratio, along with resistance to pitting and crevice corrosion, positions it as an excellent choice for offshore structures, propellers, and fasteners.

Bronze and Brass Alloys

These copper-based alloys offer good corrosion resistance and are often chosen for marine components such as propellers, bearings, and bushings. They are valued for their ease of machinability and reliable performance in saltwater environments.

Plastics and Composites

In some cases, non-metallic materials are preferred due to their resistance to corrosion, lightweight nature, and electrical insulating properties. Fiberglass-reinforced plastics (FRP), for example, are used in marine applications such as hulls, decks, and piping.

In addition to selecting corrosion-resistant base materials, we also offer a range of coatings and surface treatments. Protective coatings like epoxy coatings, anti-fouling paints, and galvanization further enhance the resistance of components against the harsh marine environment.At Be-Cu, we recognize that the choice of materials profoundly influences the performance, safety, and maintenance requirements of marine systems. Our expertise lies in meticulously assessing the specific requirements of each component and selecting the optimal corrosion-resistant material. Whether it’s a propeller shaft subjected to constant immersion or a navigation console exposed to sea spray, our commitment to quality ensures that our clients receive components that endure the challenges of the marine environment.

Furthermore, we continually stay abreast of material advancements and industry trends to provide our clients with the most innovative and reliable solutions.
