IS 419:2020 is the Indian Standard (BIS) for leaded tin bronze rods and bars. IS 419 covers leaded tin bronze in wrought (rod/bar) form — the same alloy system as IS 318 (castings) but in cold-drawn/extruded form. Used for machined bearing bushings, thrust washers, and precision wear components.

Specification for leaded tin bronze rods and bars for general engineering, covering grades, chemical composition, and mechanical properties.

Practical Notes

! IS 419 (wrought rod/bar) has higher strength than IS 318 (cast) due to cold working.

! Used to machine precision bushings and bearings on CNC lathes.

! Lead content provides self-lubrication and machinability.

Standard Specification for Phosphor Bronze Rod, Bar, and Shapes

ASTM B139 covers phosphor bronze (no lead). For leaded bronze rod, ASTM B140 applies.

Key Differences

≠IS 419 = leaded tin bronze (Cu-Sn-Pb). ASTM B139 = phosphor bronze (Cu-Sn-P, no lead).

Key Similarities

≈Both cover wrought copper alloy rods/bars for engineering applications.
