If it is made up of copper, zinc, brass is called the ordinary brass. If it is by two or more elements of a variety of special brass alloy is called. Such as lead, tin, manganese, nickel, iron, copper alloy composed of silicon. Brass strong wear resistance. Special brass also called special brass, its high strength, high hardness, strong resistance to chemical corrosion. It is also more prominent on the mechanical properties of the machining. Draw by brass seamless copper tube, soft, strong wear resistance. Brass seamless tube can be used in heat exchanger and condenser, low temperature, undersea pipeline transportation pipe. Manufacturing sheet, bar, rod, tube, casting parts, etc. Copper was 62% ~ 68%, strong plasticity, pressure equipment, etc.
According to the kind of alloy elements contained in the brass, brass is divided into ordinary brass and two special brass. Pressure processing in brass as the deformation of brass. Leaded brass leaded brass (commonly known as the free cutting brass) : lead actual insoluble in brass, went into a state of free particle distribution on the grain boundary. Leaded brass according to its organization is alpha and (alpha + beta) two kinds. Alpha leaded brass due to the harmful effects of lead is larger, the high temperature plastic is very low, so the only cold or hot extrusion deformation. (alpha + beta) leaded brass has good plastic under high temperature, can be forged. Beryllium bronze beryllium bronze is a kind of beryllium copper alloy containing (Be0.2 ~ 2.75% wt %), of all the beryllium alloy is a kind of, the use of the most widely used in today's world has been more than beryllium 70% of the total consumption. Beryllium bronze is precipitation hardening alloys, after solid solution aging treatment has high strength, hardness, elastic limit and fatigue limit, elastic hysteresis is small, and a corrosion resistant (beryllium bronze alloy in seawater corrosion speed: (1.1 1.4) x 10-2 mm/year. Corrosion depth (10.9 13.8) x 10-3 mm/year.) After corrosion, beryllium bronze alloy strength, elongation, no change in still water can keep more than 40 years, beryllium copper alloy is a submarine cable repeater constructs an irreplaceable material. In sulfuric acid medium: beryllium bronze (room temperature) in less than 80% concentration of sulfuric acid corrosion depth of 0.0012-0.1175 mm, the concentration of corrosion is greater than 80% is a bit faster.
