Oxygen transport analysis in lead-bismuth eutectic coolant for …

1. Introduction. Corrosion is a critical problem that restricts the development of lead-based fast reactors (LFRs). When the stainless steel is in contact with lead-bismuth eutectic (LBE), dissolution corrosion or oxidation corrosion may occur, depending on the oxygen concentration (Zhang et al., 2020).For the low oxygen concentration, the alloying …

Why Companies Are Switching from Lead to Bismuth

Many companies are moving away from lead and copper and tin alloys due to the regulations and toxicity associated with the heavy metal, and that often means choosing bismuth. The good news is that bismuth has a relatively low melting point, and it's durable and malleable when combined with other metals. Lead is used in copper and tin alloys ...

Lead (Pb) in Hot Dip Galvanizing

In the UK a stadium had its roof support structures crack due to tin in the zinc. Too much bismuth causes white rust. Lead in the zinc increases the reactivity of malleable cast iron and produces coating that side off the castings.

Electrodeposition of tin-zinc-bismuth alloys from aqueous citrate-EDTA

Sn–Zn–Bi alloys layers were, for the first time, successfully produced by electrodeposition from stable and homogeneous aqueous electrolytes based on citric (Cit) and ethylenediaminetetraacetic (EDTA) acids. The optimal conditions for electrodeposition of Sn–Zn–Bi alloys from Cit-EDTA baths are in the narrow pH range of between 3.5 and 4.5.

Applications: Industrial

Bismuth acts very much like lead in many respects. It is lead's neighbor on the Periodic Table of the Elements, and its melting point is 56° C (101° F) lower than that of lead, making its behavior during casting and solidification similar to that of lead. Like lead, bismuth is nearly insoluble in copper and copper alloys.

A.Y. McDonald's No-Lead Brass contains a high percentage of copper and 3 main alloying elements - Zinc, Tin and Bismuth. Zinc is a potent alloying element in copper, imparting strength and hardness. Tin is a potent solid-solution strengthener in copper, even more so then zinc. Unlike zinc, tin also improves corrosion resistance.
