Admiralty Brass Tubes is a zinc and copper-based alloy that contains minor amounts of arsenic and zinc. These tubes are recognized for their outstanding corrosion resistance in filthy river water, clean seawater, as well as slow-moving and stagnant water. Admiralty brass tubes are zinc-copper alloy with trace amounts of arsenic and zinc. These tubes are well-known for their great corrosion resistance in filthy river water, pure seawater, and slow-moving and stagnant water. The brass having 30% of zinc and tin of 1% and is inhibiting dezincification in several atmospheres and is widely used the material in tube manufacturing. There are many good features it possesses is high thermal conductivity, high strength, light-weight, corrosion-resistant etc. All of our tubes have a wide range of characteristics, including adaptability, corrosion resistance, increased thermal conductivity, ease of joining and installation, problem-free performance, and simple maintenance. We provide the option of customizing tubes with application-specific features to meet the needs of the coolers and evaporators business.The sector offers a wide selection of products to buyers, allowing for the fulfilment of all application requirements. The product is made available to buyers in a variety of sizes, wall thicknesses, grades, schedules, lengths, specifications, and standards. Along with the high quality of value-added and sales after-sales services, the product provided is priced reasonably.
