Description and applications
|
|
|
|
|
150 HB
|
Rebuilding or hardfacing of parts subjected to metal to metal wear under high pressure in the presence of corrosive media. Examples : pumps and pump bodies, valve disks, valves, propellers, gears |
|
|
|
|
210 HB
|
Rebuilding of bronze castings, slideways, valve gates, cryogenics. |
Cupro-aluminium alloy with added Fe, Ni and Mn to improve the mechanical properties while maintaining the corrosion resistance. Resist temperatures up to 300°C. Corbronze 201 keeps its good room temperature mechanical properties up to 200°C. |
|
|
|
|
320 HB
|
Pistons for injection of aluminium under pressure, valve seats, rolls for paper making machinery. |
|
|
|
|
420 HB
|
Deep drawing dies, friction and contact sliders for lifting equipment. |
|
|
|
|
210 HB
|
Heat exchanger elements for sea-water desalination equipment, tidal power station components. |
Specially adapted to resist corrosion in marine environments. The presence of nickel in the deposit imparts resistance to attack by hot, turbulent sea-water and super heated steam. Very good resistance to stress-corrosion and cavitation |
|
|
|
|
320 HB
|
Boat propellers, shafts, bearings undergoing corrosion and frictional wear. |
|
|
|
|
420 HB |
Friction plates, dredger bucket axles |
|
|
|
|
210 HB
|
Gear teeth, pump shaft, stripper columns |
These alloys are particularly noted for their self-lubricating qualities involving metal to metal rubbing under heavy loads. |
|
|
|
|
320 HB
|
Friction plates, bearings, sliders, high speed bearings |
|
|
|
|
420 HB
|
Deep drawing dies for stainless steel, aluminium, magnesium and titanium parts. |
|
|
|
|
210 HB
|
Cast boat propellers according to American specification Mil-B-21230-A
The deposit is specially enriched in manganese in order to resist the combined effects of corrosion, erosion and cavitation. |
