Copper Round Tube 122, also known as Tough Pitch Phosphorus Deoxidized (TPHP) copper, is a widely used grade known for its excellent weldability and brazeability. This alloy has a minimum copper content of 99.90% and contains a small amount of phosphorus, which improves its resistance to hydrogen embrittlement at high temperatures. Its good thermal and electrical conductivity, combined with its formability, makes it suitable for various applications. Common uses include plumbing, refrigeration lines, and heat exchangers where reliable joining and corrosion resistance are important.
