C27400/H63 Brass Bar
C27400 copper bar is made from an alloy with high strength, good plasticity and excellent corrosion resistance. Its chemical composition mainly includes copper and zinc, as well as trace amounts of lead, iron, and aluminum. It is widely adopted in electrical, decorative, automotive and construction fields.
PRODUCT DESCRIPTION
C27400 copper alloy is mostly composed of copper and zinc. Small amounts of lead, iron and aluminum are combined to improve processing properties and mechanical properties of the bar. While maintaining the good electrical and thermal conductivity of copper, adjusting the proportion of zinc can give it higher strength, making it an ideal choice for processing and forming. Besides, C27400 alloy has good processing properties and can be formed by cold working and hot working. C27400 bar is often used to make decorative parts, door handles and furniture accessories due to its good polishing performance and golden luster.
