Red Round Solid Copper Bar Modern Copper Profile H62 H63 Brass Profile

Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is a variety of alloys composed of more than two elements, it is called special brass. Brass has strong wear resistance. Brass is often used to make valves, water pipes, connecting pipes of internal and external units of air conditioners, radiators, etc.
The mechanical properties of brass vary with the zinc content. about α Brass, with the increase of zinc content, σ B and δ Are increasing. For( α+β) The strength of brass at room temperature increases continuously before the zinc content increases to about 45%. If the zinc content is further increased, the strength will be sharply reduced due to the appearance of more brittle r phase (solid solution based on Cu5Zn8 compound) in the alloy structure. ( α+β) The room temperature plasticity of brass always decreases with the increase of zinc content. Therefore, copper zinc alloy with zinc content more than 45% has no practical value.
