BLUEWAVE® U21
- Good hot forming properties
- Good machinability with adapted tools and parameters
- Very good stress corrosion and dezincification resistance
- Particularly adapted for High strength properties application
- Scraps recycling: CW724R scraps have to be handled and maintained fully separated from other alloys
Applictions of BLUEWAVE® U42
- All products needing to meet high tensile strength and elongation properties
- All products needing to meet Californian law AB 1953
BLUEWAVE® U42
- Excellent forgeability
- Good machinability with adapted tools and parameters
- Excellent thread-rolling, polishing, plating and brazing capability
- Scraps are fully-recyclable and mixable with standard leaded alloys (i.e. CW614N, CW617N or US alloys C36000, C37700)
- High performances at a reasonable price
Applictions of BLUEWAVE® U42
- Drinking water taps and fittings
- Forged valves and valve bodies
- All products needing to meet the Californian AB1953
BLUEWAVE® U38A
- Excellent cold deformation
- Excellent stress corrosion cracking resistance
- Excellent dezincification resistance
- Good hot forging performances
- Recycling with standard DZR alloys
- Good thread rolling, brazing, polishing and plating capability
Applictions of BLUEWAVE® U38A
- In case of aggressive or scaling water.
- In case of high temperature working conditions.
- All products needing to meet the Californian AB1953 and the US standard NSF/ANSI 14 as far as dezincification and stress corrosion resistance are concerned.
BLUEWAVE® U40
