Aluminium messing rør C68700
Hæmmede aluminium messingrør - C68700 – Modstår virkningen af salt med høj hastighed og sortligt vand og bruges almindeligvis til kondensatorrør. Hovedkarakteristikken ved C68700 er dens høje modstandsdygtighed over for impingementangreb. Rør af denne legering anbefales til brug i marine og landkraftværker, hvor kølevandshastigheder er høje.

Aluminium brass tubes are highly accepted and one of the extensively used material for various industrial applications. This alloy develops a protective film that has self-healing properties. This film is dependent on oxygen, which is dissolved in the water and does not renew itself in polluted or stagnant water. High resistance to corrosion in clean seawater or inland conditions is difficult.
Aluminum Brass tubes resist the action of high-velocity salt and brackish water. The outstanding characteristic of this alloy is its superior resistance to impingement attack.
High strength combined with good general corrosion resistance and low susceptibility to stress corrosion cracking of aluminum brass tubes make it a highly preferred material for load bearing masonry fixings.
In case, the brass tubes are used in hard drawn conditions, or if they have been severely cold worked through bending or swaging in assembly, they should generally be heat treated to ensure freedom from stress corrosion cracking.
