Why Choose CW617N As Brass Fittings’ Material

The word brass refers to copper zinc alloy, it began in the Ming Dynasty, its record in the “Ming Hui Dian” : “Jiajing, for example, Tongbao money six million wen, two fire brass forty-seven thousand 272 jin…… .

Brass A copper alloy with zinc as the principal additive element, having an attractive yellow color, commonly referred to as brass. Copper – zinc binary alloy is called ordinary brass or simple brass. Brass of more than three yuan is called special brass or complex brass.

Brass alloys containing less than 36% zinc have good cold-working properties, such as brass containing 30% zinc is commonly used to make shell casings, commonly known as shell brass or 733 brass.

Brass alloys containing between 36 and 42% zinc, of which the most commonly used is 64 brass containing 40% zinc. The more common marks are Hpb59-1, CW617N, JISC3771 and C37700 series.

In order to improve the performance of common brass, other elements are often added, such as aluminum, nickel, manganese, tin, silicon, lead, etc. Aluminum can improve the strength, hardness and corrosion resistance of brass, but reduce the plasticity. It is suitable for sea liner condensation pipe and other corrosion resistance parts. Tin can improve the strength of brass and corrosion resistance to sea water, so it is called naval brass, used for ship thermal equipment and propellers. Lead can improve the cutting performance of brass; This easy – cutting brass is commonly used in valves and pipe fittings.

The CW617N is characterized by good machinability, good mechanical properties and ability to withstand cold. Hot pressure processing, easy welding, brazing, good stability against general corrosion.

CW617N

CW617N is used for hot forging and pressing a variety of parts, including plumbing and sanitary ware, faucet and valve parts, automotive parts, air conditioning valves, hardware machinery, nuts and other parts requiring a high degree of precision machining.

Our brass fittings,ball valves and taps, copper parts are processed with European standard CW617N extruded copper rod, which has excellent thermal forming performance, good corrosion resistance and high processing grade. Through CNC machining, it has the characteristics of high precision and bright surface.
