COPPER ALLOY SMLS TUBE SB111 C44300 O61 ANNEALED ADMIRALTY BRASS
Overview
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.
