Introduction

Copper is a lot easier to alloy than most other metals. Its properties are strengthened and improved when alloyed to suit specific environments and applications. Lead is often added to copper alloys to enhance their machinability. Addition of lead does not affect the structure and properties of copper as it is basically insoluble in solid copper. UNS C98600 is a leaded casting copper alloy.

The following datasheet discusses the chemical composition and properties of copper UNS C98600.
