Nestled in the industrial heart of Amman, Sabra Metals has built a strong reputation as a trusted manufacturer and supplier of high-grade non-ferrous metals. Our specialization in Copper Nickel, or Cupronickel, hex bars is a particular point of pride. We understand that precision and reliability are paramount, which is why we are committed to producing hexagonal bars that meet the most demanding international standards, providing our clients across Jordan and beyond with materials they can count on for even the most challenging projects.
The exceptional quality of our Copper Nickel hex bars stems from their specific composition and resulting strength. Typically crafted from alloys like 90/10 or 70/30 copper-nickel, these bars are further enhanced with small additions of iron and manganese. This formulation grants them outstanding mechanical properties, including impressive tensile strength and excellent ductility. Most notably, they possess a remarkable resistance to corrosion, especially in aggressive marine environments, and are highly resistant to biofouling, making them a fundamentally durable and long-lasting material choice.
