UNS C44300 Admiralty Brass

Alloy C44300 tubing,  Admiralty brass C44300,  Copper alloy C44300 sheet

Brass is a copper alloy with zinc and a small amount of other alloying such as Arsenic adding which can inhibit the corrosion and improve the corrosion resistance. Alloy C44300 also known as admiralty brass and has good mechanical properties. Brass C44300 of lkalloy supplying is available in tubing and sheet. C44300 brass tubing offers excellent cold workability for forming and bending, ideal for heat exchangers and pipes that transporting corrosive liquids.
