Gunmetal castings, lead-free

Lead-free Gunmetals G1, G2, G3 are alloys mainly utilised as shaped castings with Admiralty gunmetal G1 being the most commonly used. They are now however, becoming less common since the leaded metals especially LG4, can offer similar mechanical and corrosion resistant properties coupled with an improvement in pressure tightness and castability.

Gunmetal castings, leaded

The Leaded Gunmetals LG1, LG2, LG3 and LG4, are the most popular group of alloys for general casting purposes. LG2 is used for the production of such items as valve bodies and fittings, impeller and centrifugal pump bodies.
It offers moderate cost and good corrosion resistance however, LG4 offers improved mechanical properties and better resistance to impingement and cavitation attack in contact with fast moving waters. LG3 is somewhat intermediate in properties between LG2 and LG4. The remaining alloy has the distinct advantage of lower cost but is inferior in all other respects to the other three alloys in this group.
