The Difference Between Copper Nickel 70/30 Round Bar and Copper Nickel 70/30 Precision Ground Bar

Copper Nickel 70/30 Round bar is exactly as it sounds; a long, cylindrical metal bar. Copper Nickel 70/30 Round bar is available in many different diameters ranging from 1/4" up to 24".

Copper Nickel 70/30 Precision ground bar is manufactured through induction hardening. Induction hardening is a non-contact heating process which uses electromagnetic induction to produce the required heat. Copper Nickel 70/30 Centerless ground bar is typically produced by turning and grinding the surface to a specified size.

Copper Nickel 70/30 Precision Ground Bar, also known as ‘Turned Ground and Polished’ shafting, refers to round bars made with fine precision and high-quality steel. They are polished to ensure flawless and perfectly straight surfaces. The manufacturing process is designed for extremely close tolerances for surface finish, roundness, hardness, and straightness which ensures a long service life with reduced maintenance.

Benefits of 70/30 copper nickel bar

  • Excellent corrosion and pitting resistance in marine environments
  • Good strength and toughness
  • Resistance to biofouling
  • Readily weldable and fabricated
