Introduction

Tellurium is often used by metallurgists to produce metal alloys. It can be a minor additive for copper alloys, reducing copper's conductive properties, thereby making the product easier to work. When tellurium is added to lead alloys, the durable product is more resistant to fatigue and vibration.

The following datasheet will provide an overview of lead-tellurium alloy.
