C67410 Manganese Bronze: Premium Marine-Grade Wear Alloy
(ASTM B584 C67410 | UNS C67410 | CuZn35Mn2AlFe)
Cu 58-62% · Zn 34-38% · Mn 1.5-3.0% · Al/Fe 1-2% · Saltwater Defender · Heavy-Load Specialist
Product Overview: The Corrosion & Impact Warrior
Trusted by Shell Offshore for subsea valve components and Hitachi Construction for excavator joints, C67410 delivers unmatched performance in corrosive, high-stress environments. This aluminum-enhanced manganese bronze withstands seawater corrosion rates 50% lower than standard bronzes while absorbing 2x more impact energy than steel. With ISO 9001-certified production, it's the go-to alloy for marine hardware and heavy machinery requiring zero-failure reliability.
