Phosphor Bronze Round Bar Manufacturers in India – ASTM B139 C52100 Grade Bars Offering Excellent Elasticity, Strength, Durability and Conductivity

Nandigram Metal Industries is a reputed Phosphor bronze round bar manufacturer, which provides high-performance copper alloy round bars that are used in strenuous industrial applications. Phosphor bronze round bars possess high strength, are resistant to corrosion, have a fine grain structure, and possess high wear characteristics, which make them ideal for both precision engineering and high-duty applications.

Key Features & Benefits

  • Very good wear and abrasion resistance.
  • Good fatigue strength and toughness.
  • Exceptional corrosion resistance in the industrial and marine applications.
  • Low coefficient of friction
  • Excellent anti-seizing and bearing properties.
  • Good machinability and formability.
  • Elevated thermal and electric conductivity.

Technical Aspects

Phosphor Bronze is mostly a combination of copper (Cu), tin (Sn) and a minimal percentage of phosphorus (P). Tin is a strengthening and corrosion resistant alloy and phosphorus is a deoxidizer, increases hardness, and wear resistance.

These are particularly useful round bars used in dynamic multi-load applications where there is repetitive stress cycle. Their capability to be strong at high temperatures as well as withstand deformation makes them perfect in bearings, springs and electrical parts.

Phosphor Bronze Round Bars also exhibit high levels of fatigue crack resistant behavior, which has been a factor of preference in the high-precision components.
