Key features:

Arsenical leaded dezincification resistant alloy with good machining performance. Meets requirements of AS4020 for products used in contact with drinking water.

Full alloy description:

A.W. Fraser Alloy 352 is a dezincification-resistant leaded arsenical brass conforming to the requirements of A.S. 1567 alloy 352.

352 has been developed as a machining brass, which exhibits excellent resistance to dezincification in potable water systems making it suitable for plumbing fittings. Field trials have also shown it to be dezincification resistant in sea water when in the heat treated condition and is suitable for through-hull fittings.

The composition of A. W. Fraser alloy 352 is strictly controlled as are the extrusion, finishing and heat treatment operations to achieve a constant standard of quality, properties and structure. All extrusions are manufactured from continuous cast billet stock ensuring uniform dispe rsion of lead particles and freedom from porosity.

Batches of 352 extrusions are tested for dezincification resistance in accordance with A.S. 2345 – 2016 or BS 2874.

Note: No heating operation exceeding 550 °C should be undertaken on alloy 352 as this will re duce the dezincification resistance (e.g. silver soldering or brazing).
Machinability Rating: 80
SAE Grade: n/a
