ASTM Copper Nickel Bars

Maritime & Offshore

Copper nickel alloy bars released to ASTM specifications.


Keeping Things Clean

Anti-microbial Capabilities

Our copper nickel bars, which we supply to ASTM standards, are ideal for sanitary, offshore and maritime applications.


ASTM B151 outlines the requirements for copper-nickel zinc alloys in bar or rod form, including chemical composition and different tempers. ASTM International is a United States-based organisation that achieves collaborative consensus and publishes technical standards for specific materials and products.

About ASTM Copper Nickel Bars

Our copper nickel bar products (also called cupronickel) are popular within the marine and offshore industry, along with sanitary applications due to the alloy's strength, corrosion resistance and anti-microbial capabilities. We stock various material grades under equivalent specifications such as British Standards and Euro Norm.

Cost Effective

Our stock range includes closer incremental sizes, which means that once you purchase solid round bars from us, it often negates the need for machining down. Stocking products in this way ultimately save you time and money.
