Materials
Materials Options
Steel
Marine-grade carbon steel and stainless steel are the most widely used and fundamental materials in marine applications, offering excellent machinability, high strength, corrosion resistance, and weldability. They are ideal for manufacturing propellers, anchors, platform legs, shafts, valve stems, and hydraulic cylinder piston rods. Additionally, we offer DLC coatings and PVD coatings.
Aluminum
Marine-grade aluminum alloys, particularly the 5xxx and 6xxx series, are highly favored in marine applications due to their lightweight properties and excellent corrosion resistance. They are ideal for manufacturing valve blocks, sheaves, instrument housings, steering nozzles, heat exchangers, rudder quadrant, jet drive impeller, hatch latch, outrigger mount, and ROV thruster propeller, hydraulic fittings, and precision mounting brackets.
Copper
Copper alloys, particularly copper-nickel alloys, are renowned in marine applications for their exceptional resistance to biofouling and corrosion. Combining excellent electrical and thermal conductivity, they are ideal for manufacturing propeller shaft bearings, valve seats, pump wear rings, propeller nuts, thru-hull fittings, silicon bronze screws, and pipe unions.
Titanium
Titanium and its alloys are premium materials in marine engineering, renowned for their near-perfect corrosion resistance and extremely high strength-to-weight ratio. They are ideal for manufacturing propeller shafts, subsea sensor housings, arm components, custom rigging fittings, heat exchanger tube sheets, pump impellers, and acoustic transducer housings.
Instant & Accurate Quotes
We don't use online automated quotation tools, because it is very inaccurate. Online quote platforms rely solely on calculations based on cutting amounts and fixed coefficients, they fail to account for actual processing nuances, such as material deformation after heat treatment, tight tolerance requirements, grinding after heat treatment, etc. Consequently, automated price calculations can lead to inaccuracies, ultimately increasing your costs.
But you can rest assured at DEK!
Our quotations are both cost-effective and accurate because we have a team of professional mechanical engineers who meticulously review each drawing.
