Wire, round, rod 2.1061 - CuSn12Pb - C92700

Supplier — AvekGlob Company — offers wire, bar or rod made of bronze 2.1061 (CuSn12Pb) at an affordable price from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Bronze grade 2.1061 (also called CuSn12Pb alloy) belongs to the group of high-strength tin bronzes, which are additionally alloyed with lead. An increased percentage of nickel provides the alloy with resistance against high-temperature corrosion, and the presence of lead improves weldability. Bronze grade 2.1061 (CuSn12Pb) is also distinguished by good fluidity and a low degree of linear shrinkage. This alloy is melted according to the Western European standard DIN EN 1705−2001. The ingots and ingots obtained by casting are further subjected to rolling or multiple drawing to obtain the desired profile.

Urgency of application

Bronze grade 2.1061 (CuSn12 Pb) can be used in various ring and tubular structural elements, nuts under load, discs operating at significant mechanical pressures and a lack of process lubrication. Under these conditions, CuSn12Pb receives technological advantages over the CuSn12 alloy due to the presence of lead, while maintaining the same parameters of operational durability. Typical parts that are produced from the bronze in question are spindles of large machine tools, valves, worm wheels, sliding bearings of units operating under severe conditions.
