Description

Roto217-440F is a low-melt fusible bismuth-based alloy ingot. It was originally developed by GE for anchoring punches in dies and non-moving parts in machinery The composition of Roto217-440F is: 48% Bi, 28.5% Pb, 14.5% Sn, 9% Sb. According to Rotometals, it shouldn't melt at a low temperature. Roto217-440F is a low-melt fusible alloy ingot that's bismuth-based. It's used for anchoring punches in dies, anchoring non-moving parts in machinery, and holding down bolts in concrete floors. Here's some technical information about Roto217-440F: *Melting point: Solidus 218°F, 103°C; Liquidus 440°F, 227°C
