Brass Compression Fitting for PE Pipe Coupling (EM-F-A224)

In order to improve the performance of some on the brass, brass in a yuan to join other alloying elements on the basis of brass called special brass. Commonly used alloying elements have silicon, aluminum, tin, lead, manganese, iron and nickel, etc. In adding aluminum brass may improve the yield strength and corrosion resistance of brass, slightly lower plasticity.
Containing aluminum is less than 4% of the brass has a good processing, casting and other comprehensive performance. Add 1% to the brass tin can significantly improve seawater and Marine atmospheric corrosion resistance of brass, so called "naval brass".
Tin can also improve the machinability of brass. Brass leaded the main purpose is to improve the cutting machining and improve wear resistance, lead to the strength of the brass. Manganese brass has good mechanical properties, thermal stability and corrosion resistance; In manganese brass, aluminum, can improve its performance, smooth surface castings. Brass can be divided into two categories, casting and pressure processing products. Brass is an alloy of copper and zinc. The simplest of brass is binary alloy copper, zinc, called simple brass or brass.
Change the content of zinc in the brass can get different mechanical properties of brass. The higher the content of zinc in the brass, the intensity is high, the plastic is a bit low. Industrial zinc content less than 45% of brass, zinc will produce high brittleness, improves the performance of the alloy go bad. Color along with the increase of zinc by yellow and red to yellow.
Brass mechanical properties is higher than pure copper, in the general case no rust will not be corrosion; Plasticity is good, is widely used in machinery manufacturing in the production of various structure parts.
Brass with zinc as the main add elements of copper alloy, has a beautiful yellow, generally referred to as brass. Copper zinc simple binary alloy called ordinary brass or brass.
The three yuan brass called special brass or brass complex. With less than 36% zinc brass alloy is composed of solid solution, has a good cold working performance, such as zinc 30% of brass are commonly used to make shell casings, commonly known as cartridge brass or 5 brass.
Zinc in 36 ~ 42% between the brass alloy composed and solid solution, the most commonly used are zinc 40% of June 4 brass. In order to improve the performance of the common brass, often add other elements, such as aluminum, nickel, lead, tin, silicon, manganese, etc. Aluminum can improve the strength of the brass, hardness and corrosion resistance, but reduce the plastic, for vessel condenser pipe and other corrosion resistant parts. Tin can enhance the strength of the brass and the seawater corrosion resistance, therefore calls the navy brass, used as a heating equipment and the propeller of the ship.
