Brass Copper & Zinc Alloy Foils Roll - Coil - Sheet - Strip - Tape
Brass Information :
Brass is mainly an alloy that consists of copper with zinc added. Brasses can have varying amounts of zinc or other elements added. These varying mixtures produce a wide range of properties and variation in color. Increased amounts of zinc provide the material with improved strength and ductility. Brass can range in color from red to yellow depending on the amount of zinc added to the alloy.
If the zinc content of the brass ranges from 32% to 39%, it will have increased hot-working abilities but the cold-working will be limited.
If the brass contains over 39% zinc, it will have a higher strength and lower ductility (at room temperature).
Applications
Brass is commonly used for decorative purposes primarily because of its resemblance to gold. It is also a commonly used to make musical instruments due to its high workability and durability.
Other Brass Alloys
Tin Brass
This is an alloy that contains copper, zinc and tin. This alloy group would include admiralty brass, naval brass and free machining brass. The tin has been added to inhibit dezincification (the leaching of zinc from brass alloys) in many environments. This group has low sensitivity to dezincification, moderate strength, high atmospheric and aqueous corrosion resistance and excellent electrical conductivity. They possess good hot forgeability and good cold formability. These alloys are typically used to make fasteners, marine hardware, screw machine parts, pump shafts and corrosion-resistant mechanical products.
Technical Data :
It’s physical properties are showed as bellowing:
- Density:8.5g/cm3
- Electric conductivity(20°C ): 27%IACS
- Thermal conductivity (20 °C): 120W/(m °C )
- Elastic modulus: 105000N/mm2
- Thermal expansion coefficient (20-300 °C ) 20 X 10 -6 °C -1
Brass Properties
- bright gold appearance
- higher malleability than bronze or zinc
- acoustic properties appropriate for use in musical instruments
- low friction
- soft - may be used where low chance of sparking is necessary
- relatively low melting point
- easy to cast
- not ferromagnetic (which makes it easier to separate from other metals for recycling)
