UNS C37700 Copper Alloy Chemical Composition, Grade, Chart and Document

The most ideal UNS C37700 is an amazing ductile copper alloy. It has the fantastic ability to fight against corrosion and is the best conductor of heat. Copper alloy with lead and zinc is the main ingredient of its composition, and it belongs to cast copper alloy type. This alloy is mainly used in applications that need through machining which are fittings, valves and connectors. These are widely used in plumbing. The chemical composition however, normally has 59-63% copper, 0.25-1.0% lead, 1.5-2.5% zinc and lower percentages composition of some other elements. High-grade material makes it strong and versatile for application in different situations. There is a master chart for operability of all the alloys and this leads to better selection of the desired alloy for different industrial processes. Relevant documents give a complete picture on a product things such as the properties, the applications and how it should be handled, which help it to perform at the highest levels in every scenario.

UNS C37700 Copper Alloy Chemical Composition And Grade Table

UNS C37700 is a copper alloy which has a good grade of machineability, high resistance to corrosion, and high rate of thermal conduction as well. Being a copper (Cu) product with small additions of lead (Pb) and the zinc (Zn), its chemical composition ranges between 59% to 64% which is the copper content, 1% to 2.5% is lead and 0.5% to 2.5% is the zinc content and the remaining is made up of other trace elements. This alloy is one of the most widely used for plumbing fittings, valves and different parts, that requires high of machinability and resistance to dezincification. Its eight digit grade is a classification of leaded brass that demonstrates the combination of hardness and workability.
