464 Brass Round Bar, Unpolished (Mill) Finish, H02 Temper, ASTM B21, 0.25" Diameter, 12" Length, OnlineMetals

The 464 brass round rod with H02 temper is unpolished, meets American Society for Testing and Materials International ASTM B21 specifications, and has a standard tolerance. The 464 brass alloy, also known as naval brass, has high corrosion resistance, especially to salt water, and provides good strength due to its high zinc content. The material has an H02 temper, meaning it has been cold worked to a 1/2 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.
