Copper bars and copper alloy bars are useful for numerous applications. Copper bars are more ductile, with higher electrical and thermal conductivity and better machinability as compared to bars of other metals. Copper bar also has a characteristic pinkish metallic luster that makes it useful for decorative applications.

Copper component manufacturers use copper bar stock as the raw material and process it further to produce the finished products. Different components which require copper bar stock as a raw material are electronic and electrical components, gears, valves, aircraft and automotive parts and fittings, medical devices and measuring instruments.

Some important parameters you must consider before buying copper bars are:

1. Application of the copper bar
2. Physical properties of the copper bar : cross section shape and dimensions
3. Composition and metallurgical properties of copper bars
4. Required quantity of the copper bars

Tips & Tactics

Helpful advice for making the most of this Guide

• •  For buying customized copper alloy bars, consult an expert as the properties of copper alloy bars depend upon the composition.
• •  You must polish or coat decorative copper bars, as copper is less resistant to oxidation and loses its characteristic pink luster when exposed to air.
• •  Ask the producer of copper bars about the ASME (American Society of Mechanical Engineer) and ASTM (American Society for Testing and Materials) standards referred by them.
