C27000 Hexagonal Brass Bar
C27000 brass is a copper-based alloy with zinc as the principal alloying element that gets its name from its golden yellow tint. Simple brass, often known as "ordinary brass," is a copper-zinc binary alloy. Varying the zinc concentration of brass can result in brass with varying mechanical characteristics. The more zinc there is in brass, the stronger it is and the less plastic it is. C27000 brass has a lovely color, good process and mechanical qualities, high electrical and thermal conductivity, corrosion resistance in air, freshwater, and seawater, is easy to cut and polish, has good weldability, and is inexpensive. widely used in the manufacture of electrical and thermally conductive components, corrosion-resistant structural parts, elastic components, everyday hardware, and ornamental materials, among other things.
C27000 has stronger strength than purple copper, good electrical and thermal conductivity, high corrosion resistance in the atmosphere and fresh water, and good plasticity, as well as being easy for cold and hot pressure processing, welding, forging, and tin plating and having no stress corrosion rupture. It is frequently used in the production of valves, water pipes, air conditioning internal and exterior machine connection pipes, and radiators, among other things.
