Leaded Bronze – Materials and norms

Leaded Bronze

Leaded bronzes include alloys with a higher lead content (approximately over 10%). The addition of lead softens the material, improves its machinability and most importantly, decreases the coefficient of friction. So this material is especially suitable for bearings (and their housings or shells), which must work with a small amount of lubricant or completely dry. Other surcharges ensure the uniformity of the structure.

We supply bronze in the form of bars (round, flat, square, hexagonal, hollow), tubes or sheets.

Below you will find a selection of the most common material grades we work with. If you are interested in another grade or alloy, do not hesitate to contact us.
