AS1565‑1985 C83600 Leaded Gunmetal Bronze for Bearings, Bushes & Hydraulic Components

LG2 Leaded Gunmetal Bronze (C83600) is a high‑performance copper‑based alloy used extensively across engineering, hydraulic, mining, and industrial applications. Manufactured to AS1565‑1985, LG2 offers an ideal balance of strength, machinability, corrosion resistance, and pressure‑tight casting properties. Originally developed in the 19th century for ordnance components, “gunmetal” has evolved into a trusted engineering alloy. LG2 contains controlled additions of tin (4–6%), lead (4–6%), zinc (4–6%), and nickel (up to 2%), with the remainder copper — producing a versatile bronze suitable for bearings, pump components, and pressure‑retaining parts. M&G Industrial stocks a wide range of LG2 Bronze Hollow Bar and LG2 Bronze Solid Round Bar for precision machining, turning, and fabrication.

Why Choose LG2 Leaded Gunmetal Bronze?

Excellent Machinability

Lead is insoluble in copper alloys and forms fine globules throughout the structure, providing:

• Smooth machining
• Reduced tool wear
• Improved chip control
• Excellent surface finish

Superior Bearing Performance

LG2 is widely used for bearings and bushes due to:

• High conformability
• Ability to accommodate slight misalignment
• Good performance under variable or alternating loads
• Reliable operation with limited lubrication

Corrosion & Wear Resistance

Ideal for:

• Corrosive water environments
• Mildly corrosive fluids
• Industrial and mining applications
• Oil industry components

Pressure‑Tight Casting Properties

Perfect for hydraulic and fluid‑handling components requiring leak‑free performance.

Typical Applications

LG2 Bronze is commonly used for:

• Bearings & bushes
• Valve bodies & pump bodies
• Hydraulic fittings (taps, cocks, elbows, pipes)
• Steam packing metals
• Rolling mill bearings
• Paper‑making machinery liners
• Pump parts for corrosive environments
• Oil industry bearing components
