Copper Alloys C44300 | Product Overview
Introduction To Copper Alloys C44300 ADMIRALTY BRASS
MOKSH TUBES & FITTINGS LLP is a reputed manufacturer, supplier, and exporter of high-quality C44300 Admiralty Brass products including tubes, pipes, sheets, plates, coils, and customized fabricated items. C44300, also known as Admiralty Brass, is a copper-zinc alloy with a small addition of tin (around 1%) and arsenic, which enhances its corrosion resistance—especially against dezincification in marine and brackish water environments.
Copper Alloys C44300, is particularly suited for heat exchangers and condenser tubes due to its superior corrosion resistance, high thermal conductivity, and good mechanical strength. It is one of the most commonly used brass alloys in marine and desalination applications.
