Low Melt Alloys –
Our alloy sticks are metallic blends with low melting points, used in crafting applications such as jewellery, medallions, goblets, and toy soldiers. By blending metals like lead, tin, copper, cadmium, and antimony, these alloys achieve specific melting points. With their low melting points, intricate designs can be safely cast using simple tools like a gas torch or electric hot plate. The melting point of these sticks sits between approximately 300-400*C.
High fluidity when molten ensures precise filling of moulds, resulting in high-quality castings. These alloys capture fine details necessary for medallions with logos or personalized engravings. We offer the M4670 and M4470 high temp silicones which may be used to make moulds. These moulds can withstand the heat of the molten alloy. These silicones contain very different properties, so check which one is best for your moulding application. Adding graphite powder to your moulds helps extend the life of the mould when casting alloys.
The JA6 alloy is lead free, so perfect for jewellery or anything that requires contact with the skin. The JA7 is the most cost effective and is perfect for casting thicker parts. The JA8 alloy offers superior ductility than some other low melt alloys, meaning that it can be partially bent without breaking. And the JA12 offers high strength, great definition, and superior polishing.
Their low melting temperatures reduce the risk of damaging heat-sensitive materials. Molten low melt alloys with low viscosity accurately reproduce intricate features in moulds. These alloys penetrate tight spaces, resulting in precise small-scale components. Overall, low melt alloys provide an efficient solution for creating various metal components combining ease of use, excellent castability, and high-quality results.
