Bismuth Cast Sticks Rod

Bismuth Cast Sticks Rods are part of our wide range of advanced rods. They come in 7 variations that differ in diameter and length. Bismuth has a low melting point and high density, making it useful for casting applications. Which is why these rods are ideal for being melted and poured into molds to create custom shapes. They’re also valued in alloys and solders due to bismuth's ability to create low-melting eutectic systems. With their unique properties, our Bismuth Cast Sticks Rods allow for flexibility in prototyping and casting operations.
