Copper Alloy Flanges

Superiror Steel Overseas is the most trusted manufacturer, supplier and exporter of Copper Alloy Flanges in national as well as international market. With the help of high-grade materials and advanced machinery, we manufacture these Copper Alloy Flanges and deliver them all around the world. We have various types, sizes, shapes, dimensions and specification flanges available at our modern warehouse.

Copper is alloyed with various metal elements and formed copper alloys that highly demanded in several industries. The alloyed copper is used to form Copper Alloy Flanges, which offer outstanding resistance to general, crevice and pitting corrosion over a wide range of temperature. Moreover, these Copper Alloy Flanges possess excellent workability, good mechanical properties, and high welding characteristics.

These Copper Alloy Flanges are easily found in diverse industries including food processing, paper & pulp application, boiler industries, heat exchangers, power generation and many more. We have several types of Copper Alloy Flanges like Copper Alloy Slip On Flanges, Copper Alloy Threaded Pipe Flanges, Copper Alloy Forged Flanges, Copper Alloy Weld Neck Flanges, Copper Alloy Socket Weld Flanges and more.
