SP 509 Bronze Master Alloys

Get Price

Melting Temp of Alloy : 940 0C

Application: The alloy SP 509 is a ready to use alloy for imitation and fashion jewellery, imparting a pleasant yellow color. It is an all-purpose alloy, usable for both hand-made, investment cast and spin cast jewellery, and is suitable for gold and silver plating.

Recommended Practice:

Application : Casting / H-made

Casting Temp. : 10500C - 10800C

Flask Temp. [Normal Cast] : 6300C - 6500C

Flask Temp. [Stone Cast] : 5900C – 6200C

Quenching Time : 25 - 30 minutes

Notes:
The actual casting temperatures and flask temperatures shall be decided by the parameters like the section thickness of the items (thick, medium or thin), the overall size/bulk of the cast tree, the design intricacies etc.
As a thumb rule, for thinner sections higher temperatures are selected and for thicker sections lower temperatures are preferred. At the same time, designs demanding higher form filling capabilities, higher than normal temperatures are an obvious choice.
Cast Tree Cleaning & Drying procedure: After primary removal of the investment during quenching, submerge tree in a hot (80-100oC) 50% phosphoric acid solution for 15-20 minutes. Rinse well with cool water to remove remaining investment powder and base metal oxides. Dry with compressed air.
