Rashtriya Metal is one of the best Brass coil manufactures in India. We are the worldwide Brass coil suppliers. Brass coils are made from copper and zinc, have conductive properties as well as corrosion resistance, making it a perfect material for the manufacture of electrical components.
Brass coils are used as electrical connectors, can be fabricated to exacting tolerances, and cut to lengths to fit any application. Our thinly cut and wounded brass strips are light weighted and ductile. The adaptability of brass allows us to shape, cut, and form it to any lengths, size, and tolerances to create the perfect sized brass coils for your project.
