Copper Alloy 120 (C12000)
Deoxidized, Low Phosphorus Copper (DLP)
Alloy C120 copper tubing is typically known for its high electrical conductivity and corrosion resistance. While not as pure as C101(99.99%) and C102(99.95%) alloys, it still offers excellent conductivity. The small amount of phosphorus improves its corrosion resistance. This alloy can be more cost effective than alloy C101 and C102 making it a good balance between cost and performance.
