Are 90-10 and 70-30 copper-nickels susceptible to stress corrosion cracking?

They do not experience chloride or sulphide stress corrosion. They have a high resistance to ammonia stress corrosion compared to other copper alloys and do not require a stress relief anneal for seawater service.

Are 90-10 welding consumables available for welding 90-10 copper-nickel?

They are available but 70-30 copper-nickel consumables are preferred for welding both the 90-10 and 70-30 alloys due to superior deposition characteristics.

Are copper-nickel alloys susceptible to the attachment of marine organisms in seawater?

Copper-nickel alloys can harbour slimes, but the attachment of macro-organisms—such as marine grasses and shellfish—is impaired. If these do become attached under quiet conditions, adherence is poor and they can be easily removed mechanically.

Pub 126 - Resistance to Wear of Aluminium Bronzes

Chapter 10 from Harry Meigh’s book ‘Cast and Wrought Aluminium Bronzes – Properties, Processes and Structure’ describing resistance to wear of aluminium bronze alloys. It also gives details of factors affecting wear and information on alloy selection. Pub 126.

Are lead-containing solders being phased out for all engineering applications?

Lead is NOT being categorically phased out but the use of lead (and cadmium) is being increasingly recognised as being undesirable both in terms of the long term environmental impact and recyclability of products. The End of Life Vehicles (ELV) Directive (2000/53/EC), the RoHS Regulations (2002/95/EC) and WEE Directive (2002/96/EC) prevent the use of certain hazardous substances including lead (and cadmium) containing materials. The use of leaded solder in potable water systems has also been prohibited in Europe and in many countries worldwide.

Copper-nickel Welding and Fabrication - Pub 139

This publication provides an understanding of the two primary copper-nickel alloys to allow good fabrication and operational practices to optimise in-service performance. Topics covered include general engineering properties of 90/10 and 70/30 copper-nickels, welding and fabrication practices and a basic overview of corrosion and performance in seawater immersion trials. 2018. 32pp.
