Corrosion of copper alloys in seawater can be mitigated. This publication offers practical guidance on alloy selection, design and preventative measures and has been written principally for marine, mechanical and other engineers who have to select materials of construction but do not have a corrosion background. 2018. 20 pp.
Probably due to the high iron content from recycled scrap. If a non-magnetic copper alloy is required use a nickel aluminium bronze to Def Stan Specifications (were NES).
This publication, aimed at material specifiers, details the many reasons why copper is the number one material for pipework services. In addition to the information on copper tube and fittings, there is environmental information on copper, its sustainability and recyclability. 2009. 12pp
Detailed advice on machining as a production technique. Guidance on materials selection where good machinability is important. Basic information and guidance for those who know what material is to be machined. Advice on the selection of cutting fluids. 1992. 65pp.
Nickel silvers are silver/white coloured copper alloys with varying additions of zinc and nickel. This publication gives information on mechanical properties, typical applications, joining techniques, heat treatment, fabrication, surface finishing. 1965. 27pp.
Yes, brass and bronze alloys are available.
Yes, but not cleaners that contain ammonia.
Yes, with care and the correct procedure.
Some alloys can, including copper-beryllium, copper-chromium and copper-nickel-silicon. Most unalloyed coppers and brasses can only be softened by heating.
Yes. Copper tubes do not become brittle at low temperatures. The relevant standard is ‘Seamless round tubes for air conditioning and refrigeration’, BS EN 12735: 2010 Part 1: Tubes for Piping Systems, Part 2: Tubes for Equipment.
Yes they can be brazed by all processes. Appropriate silver brazing alloys should be used as phosphorus bearing brazing alloys cause a reaction with nickel to form a brittle phosphide phase.
Yes they can using appropriate 65% nickel-copper consumables to avoid iron dilution effects.
