Copper-Nickel
Copper-nickel alloys are widely recognized in naval and marine engineering for corrosion resistance and biofouling resistance in seawater service — the reason this alloy family anchors our materials focus. Material solutions may include the following grades, subject to confirmed availability.
| UNS | Designation | Typical use |
|---|---|---|
| C70600 | 90/10 Copper-Nickel | A widely used copper-nickel alloy in marine piping and seawater systems. |
| C71500 | 70/30 Copper-Nickel | Higher nickel content, used where increased strength and corrosion resistance are required. |
| C71640 | Cu-Ni, Fe & Mn modified | Controlled iron and manganese additions for high-velocity seawater service. |
Brass
Brass alloys are used across naval heat-exchanger, marine hardware and general industrial applications where corrosion resistance, formability and machinability are required.
| UNS | Designation | Typical use |
|---|---|---|
| C23000 | Red Brass (85/15) | Pipe, tube and fittings. |
| C26000 | Cartridge Brass (70/30) | Cold-workable general-purpose brass for tube and formed parts. |
| C36000 | Free-Cutting Brass | Rod and bar for machined components and fittings. |
| C46400 | Naval Brass | Plate, rod and bar for marine hardware and fittings. |
| C44300 | Admiralty Brass (arsenical) | Condenser and heat-exchanger tube. |
| C68700 | Aluminum Brass (arsenical) | Condenser and heat-exchanger tube for seawater service. |
Bronze
Bronze alloys — tin bronzes, aluminum bronzes and nickel-aluminum bronzes — are widely used for valves, pumps, bearings and propulsion-related marine hardware, where strength, wear and seawater corrosion resistance are required.
| UNS | Designation | Typical use |
|---|---|---|
| C83600 | Leaded Red Brass (85-5-5-5) | Cast valve bodies, fittings and flanges. |
| C90300 | Tin Bronze (88-8-4) | Cast fluid-handling and general marine parts. |
| C93200 | Bearing Bronze (83-7-7-3) | Bearings and bushings. |
| C95400 | Aluminum Bronze | Cast parts requiring strength and corrosion resistance. |
| C95800 | Nickel-Aluminum Bronze | Widely used in marine pumps, valves and propulsion hardware. |
| C63000 | Nickel-Aluminum Bronze (wrought) | Rod, bar and forged marine components. |
Stainless Steel
Stainless steel product forms sourced against applicable grade, dimensional and testing requirements for naval, industrial and defense-related applications.
