Marmetal was founded over 50 years ago to serve the Heat Exchanger Industry. We specialize in plates and sheets for tube sheets and baffles, and condenser tubing for boilers and exchangers. All our alloys, including C365 Muntz, C443 Admiralty Brass, C464 Naval Brass, C614 Aluminum Bronze, C706 90/10 Copper-Nickel and C715 70/30 Copper-Nickel, are dual certified to ASTM B171 and ASME SB-171.
Whether you require a small quantity for prototyping, or a stocking program for recurring production, Marmetal will work with you to meet your individual requirements. Our nonferrous alloys can be found in valves, fittings, bearings, flanges, pressure vessels, clad plates and ammunition, to name a few applications. Several of our copper alloys are lead-free and have antimicrobial properties.
Marmetal’s deep stock of plates and condenser tubes, including C365 Muntz, C443 Admiralty Brass, C464 Naval Brass, C614 Aluminum Bronze, C706 and C715 Copper-Nickel, are 100% traceability to original mill test reports. Our Quality System is ISO 9001:2008 certified. We regularly accommodate witnessing of cutting and are in close proximity to several NADCAP accredited testing facilities.
Marmetal’s corrosion resistant alloys are a natural fit for marine application. The excellent resistance to seawater corrosion inherent to cupro-nickels and naval brasses can lend cost-effective solutions to the unique problems associated with saline environments. Our DFARS materials are critical to a vessel’s long-term performance, and have applications in the construction of navigation and communications equipment as well.
