Low melt alloys

At Hallmark Metals, we create high-performance, low-melt and casting alloys from only the highest quality virgin metals. All of our materials are sourced from trusted, certified providers and melted in-house under controlled conditions. The high-purity of our alloys creates minimum dross loss and higher yields, and we conduct regular XRF testing to ensure quality. Our metal alloys are perfect for casting, manufacturing, plating, wire coating, jewelry, novelty items and more.

With 20+ alloys available in stock, we can fulfill many orders next day. Our versatility allows us to often handle even custom orders with short lead times. Contact us today for more information on availability and timing.
