About 173 Beryllium Copper Round Rod, Unpolished
The 173 beryllium copper round rod with hard temper has an unpolished (mill) finish. Also called free-machining beryllium, the 173 beryllium copper alloy has the strength of alloy steel with good conductivity, corrosion resistance, and machinability. The material has been cold worked to a full hard temper.Copper, brass, and bronze are known as red metals because they contain copper, which has a reddish color. Copper, a term that applies to alloys containing at least 99.3% copper, offers very high thermal and electrical conductivity and provides corrosion resistance, formability, and machinability. Brass is an alloy of copper and varying levels of zinc, sometimes with additional elements. It provides greater strength and better machinability than copper or bronze. Bronze is commonly an alloy of copper and tin, but sometimes it is copper alloyed with other elements such as aluminum, phosphorus, manganese, or silicon. Tin gives bronze more corrosion resistance than brass and greater strength than copper. Copper and its alloys have temper designations, meaning the material has undergone a process to achieve certain properties of strength and hardness.Tensile strength, used to indicate the material's overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Formability indicates how easily the material can be permanently shaped. Machinability describes how easily it can be cut, shaped, finished, or otherwise machined, while weldability characterizes the ability to be welded.
