Description

Leaded Gunmetal Bronze Solid Round Bar LG2 Imperial

  • LG2 Bronze is one of the most used grades of bronze in the industry.
  • Has medium strength, excellent machining properties, and is suitable for bearings, gears, and other components used in relatively light-duty applications.
  • Although LG2 is often referred to as phosphor bronze, it is in fact leaded gunmetal. Only the “PB" group of bronzes (PB1, PB2, etc) can truly be called phosphor bronze.
  • PB1 Bronze Bar is also available. Contact AIMS for assistance.
  • Manufactured using finely controlled continuous or centrifugal casting techniques to ensure that hardness and strength are superior to sand-casting methods.
  • This also means that the material has a fine grain structure and is free from porosity.
  • Available in various sizes.
