High-precision Rolled Brass Foil C26800
H65(C2680) Brass , a copper-zinc alloy, is equivalent to C26800 in ASTM. Brass is a type of copper alloy hat contains copper and zinc. It is the most extensively used high precision copper alloy.
Brass has excellent dynamics properties, physical properties, high electrical and heat conductivity, and high corrosion resistance.
This material is mainly used for radiator fins, radio frequency cable,transformer,lead frame,copper cladding aluminum, water heater exchanger, automotive manufacturers.
