C27200 Brass Composition, Properties, And Uses

The chemical composition of a brass alloy has a significant effect on its properties. Some of the most essential properties of 272 brass for industrial use include:
Corrosion Resistance
The addition of tin to 272 brass creates an alloy that is resistant to water, steam, and most organic liquids, making it ideal for applications involving transfer or contact with these substances.
Strength
The higher the zinc content in 272 brass, the better its strength and ductility, with a yield tensile strength of 59,500 psi and a shear strength of 43,500 psi. The strength of this alloy is increased by cold working, making it a good material for cold headed parts, fasteners, etc.
Conductivity
As a copper-based alloy, brass has excellent electrical conductivity at about 27.6% IACS at 68°F. Electrical conductivity decreases with cold deformation and grain size.
Formability
The formability of an alloy refers to its ability to withstand deformation of shape without damage. Brasses, such as c272, are more ductile than other metals, allowing them to be cast into a variety of shapes and sizes for use as pipes, linings, and more.
Thermal Conductivity
Brass is often used to make components for heat exchangers and other applications that require accelerated heat transfer in metal parts because of its excellent thermal conductivity of 67 Btu/sq. ft./ft.-hr./°F at 68°F.
Advantages of 272 Brass
Brass has similar qualities to base copper, but the addition of zinc and other alloying agents provides additional benefits. Advantages of 272 Brass include:
Strength and hardness greater than pure copper metal and other alloys.
Reduced material cost.
Resistant in a variety of industrial environments involving contact with water, solutions, or salts.
CuZn37 is the primary alloy used in conjunction with cold forming, but is not suitable for hot working. The increase in zinc content makes c272 less expensive than other brasses, but also makes the alloy more susceptible to stress or cracking associated with dezincification - a process in which zinc dissolves from the alloy, leaving a less structurally strong material. Adding tin as an alloying agent can reduce the risk, and if such corrosion occurs, stress relief measures can be taken.
Applications of 272 Brass
272 brass alloys are widely used, with applications ranging from electrical equipment and plumbing components to architectural design pieces. Some of the most common industrial uses for C2700 brass are:
Fasteners
Cold-headed parts
Heat exchanger housings
Pump liners
There are many different brass alloys, but the qualities of 272 brass-such as corrosion resistance, excellent strength, outstanding electrical conductivity, good formability, and excellent thermal conductivity-make it a safe choice for numerous applications across a variety of industries.
