Based in Kuala Lumpur, Malaysia, Aiman Metals has evolved into a reliable manufacturer and supplier of high-quality metal products for various industries in Malaysia and beyond. Well-known for its precision and reliability, the company offers a comprehensive portfolio of specialty metals, such as Copper Nickel Rectangular Bars. With their world-class corrosion and abrasion resistance, and durability, these bars are best used for marine, chemical, and industrial uses. Customer satisfaction and quality are Aiman Metals’ top priorities, with each product guaranteed to meet international standards and performance requirements, establishing the company as a reliable business partner for critical material requirements.
Copper Nickel Rectangular Bars consist mostly of 90% copper and 10% nickel, although 70/30 copper-nickel alloys are also used extensively. Such alloys are specifically formulated to provide resistance against corrosion in marine and chemical environments along with increased strength and durability. They have tensile strengths of 300 MPa to 550 MPa and yield strengths around 150 MPa mechanically. Their elongation values typically range from 30–40%, providing flexibility when stressed. In addition to superior stress corrosion cracking, biofouling, and erosion resistance, these bars stay stable and long-lasting in rigorous service conditions.
