BRASS STRIP
Dulico is a pioneering enterprise in Vietnam specializing in the casting and rolling of brass strips — also known as brass foil or brass bands — using modern and highly automated production lines.
Brass strip is an alloy of copper and zinc in specific ratios, rolled into thin sheets and wound into coils of various sizes and thicknesses for easy transport and customization according to customer requirements.
In addition to the general properties of high electrical and thermal conductivity, good ductility, and excellent mechanical strength, Dulico brass stands out for its superior flatness, consistent thickness, uniform hardness, and clean, bright surface quality.
