Mira Fasteners is a trusted manufacturer and supplier of Copper Nickel Fasteners in Kuala Lumpur, Malaysia. Our fasteners are made from premium-grade 90/10 and 70/30 Cu-Ni alloys, offering unmatched resistance to saltwater corrosion, biofouling, and high-pressure environments. The range includes nuts, bolts, screws, washers, and threaded rods designed for marine and industrial infrastructure. Mira Fasteners produces every fastener according to international standards like ASTM B151 and DIN 2.0882. Our copper nickel fasteners are designed for critical applications, offering strength, conductivity, and high performance in harsh environmental and chemical exposure.
Copper Nickel Fasteners consist of 70–90% copper and 10–30% nickel with minor additions of iron and manganese to enhance their strength and resistance to corrosion. These fasteners provide 350–500 MPa tensile strength and superior ductility. They are resistant to pitting, crevice corrosion, erosion, and marine growth. Due to their high thermal and electrical conductance, non-magnetic properties, and resistance to temperature fluctuations, they are applicable in mechanical and marine environments. Mira Fasteners provides accurate machining and consistent mechanical properties for every supplied Cu-Ni fastener.
