LG2 Bronze (CC491K) is a leaded gunmetal alloy known for excellent machinability, good corrosion resistance, and pressure tight performance. Ideal for pump & valve components, bearings, and light to medium speed gears.

Key Features

This LG2 material combines easy machining (thanks to its leaded structure) with moderate strength, good wear resistance, and reasonable dezincification resistance in brine and seawater.

Typical Applications
  • Pump bodies and valve fittings
  • Bearings under light loads and lower speeds
  • Gears for non high load applications
  • Architectural hardware and marine fittings
  • Components in brine or salt‑water environments where machinability and corrosion resistance matter
Forms of Supply

Supplied as square bars, round bars, hex bars, flat bars, blocks, sheets, and plates in cast or continuous cast condition, Silver Metals Trading LLC, a reliable bronze supplier and non ferrous metal trader in UAE, supplies LG2 bronze across Oman and Saudi Arabia, with cut to size, machining, and finishing services available.
