Typical Uses |
C101 |
SOFT; HALF-HARD; HARD |
Electrolytic tough pitch high conductivity copper |
sheet, plate, bar & tube |
High electrical conductivity and corrosion resistance. Ductile. Limited machining capabilities. |
Electrical conductors, cold heading applications, holloware, architectural cladding. |
C106 |
HALF-HARD |
Phosphorus deoxidised non-arsenical copper (Dona) |
sheet, plate, tube |
High phosphorus content reduces electrical conductivity, but greatly increases weldability in most forms. Ductile. Limited machinability. Good corrosion resistance. |
Gas and heating installations, spinning, pressing, food processing equipment. |
CZ101 |
SOFT |
Gilding metal |
sheet |
Very good corrosion resistance. Ductile. Very good for brazing and soldering, but limited machining capabilities. Attractive golden colour. |
Jewellery, display cabinets, name plates, fascias. |
CZ106 |
SOFT |
Deep drawing brass (cartridge brass) |
sheet |
Very ductile, especially where deep pressings need to be allied with strength. Very good for brazing and soldering, but limited machining capabilities. |
Fire extinguisher bodies, lamp caps, hinges, flashlight cases. |
CZ108 |
HALF-HARD |
Common' brass |
sheet, plate, bar, tube, sections |
General purpose brass with good ductility for bending and simple presswork. Good for brazing and soldering, but limited machining capabilities. |
Instrument covers and containers, radiator tanks. |
CZ112 |
|
Naval brass |
plate, bar |
The addition of tin greatly improves corrosion resistance, especially in sea water. Good ductility if hot formed. Good for brazing and soldering, but with limited machining capabilities. |
Marine and underwater equipment. |
CZ114 |
|
High tensile brass (formerly manganese bronze) |
bar |
Combines high strenth with good corrosion resistance. Good ductility only if hot formed, good for soldering and brazing. Good machining capabilities. |
Heavy engineering, shipbuilding |
CZ120 |
HARD |
Leaded brass engraving quality (compo) |
sheet |
Good machining capabilities. Produces a good clean cut in the hard condition for close tolerances. Ductile only if hot formed. Good for brazing and soldering. |
Gears, clock parts, engraved plates. |
CZ121-Pb3 |
|
Free machining brass (CZ121-Pb4 for increased machining speeds) |
bar, hollow bar & sections |
Excellent high speed machining capabilities, but with limited cold working properties. Good for soldering and brazing. |
Machined components such as screws, nut & bolts. Architectural sections. |
CZ126 |
HALF-HARD, HARD |
70/30 arsenical brass |
tube |
General purpose brass with the addition of arsenic to reduce corrosion. |
Condensers, heat exchangers, sanitary fittings. |
CZ131 |
|
Rivetting quality brass (supersedes CZ119) |
bar |
High copper content improves ductility, whilst reduced lead content still retains limited machining properties. Excellent for soldering. Good for brazing. |
Cold heading products, rivets, screws, trye gauges. |
PB102 |
HARD |
Wrought phosphor bronze |
sheet, bar |
High strength, good resistance to corrosion and corrosion fatigue make this grade suitable for components subject to friction. Limited machining capabilities. |
Springs and instrument components. |
CA104 |
|
Aluminium Bronze |
bar |
Addition of aluminium increases strength and greatly improves corrosion resistance. Good machining properties. Suitable for hot stamping. Readily welded via mig & tig. |
Highly stresses bearings, and in the marine and chemical industries. |
SAE660 |
|
Continuous cast leaded bronze |
bar and cored bar |
Suitable for unhardened shafts which are not subject to heavy side impact loads. Lead improves machining and plasticity. Will withstand some misalignment & short periods of inadequate lubrication. |
Bearings for unhardened shafts. |
PB1 |
|
Continuous cast phosphor bronze |
bar and cored bar |
The addition of tin improves corrosion resistance and strength. Designed for bearings running with hardened shafts where good lubrication and alignment are essential. |
Bearings for hardened shafts. |
LPB1 |
|
Continuous cast leaded phosphor bronze |
bar and cored bar |
The addition of lead increases plasticity & the reduction of tin lessens corrosion and abrasion resistance in this variant of PB1 |
Lower stressed bearings and fitting such as valves. Steam pressure fittings. |
LB4 |
|
Continuous cast leaded bronze |
bar and cored bar |
Suitable for unhardened shafts which are not subject to heavy side impact loads. Lead improves machining and plasticity. Will withstand some misalignment & short periods of inadequate lubrication. |
Bearings for unhardened shafts. |
LG2 |
|
Continuous cast leaded gun metal |
bar and cored bar |
A good general alloy. Suitable where corrosion resistance and resonable bearing characteristics, but at a lower cost, are important. |
Marine industry. Some water and steam fittings, intricate tight pressure castings. |
