Wire, round, rod 2.1060 - CuSn12Ni - C91700

Wire, round, rod 2.1060 - CuSn12Ni - C91700

Supplier — AvekGlob company — offers wire, bar or rod made of bronze 2.1060 (C91700, CuSn12Ni) at reasonable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Bronze grade 2.1060 (other names — alloy C91700 or CuSn12 Ni) belongs to the group of high-strength tin bronzes, which are additionally doped with nickel. The addition of nickel to the standard 12% tin bronze provides additional durability and improved corrosion resistance in water supply systems, as well as for pipelines engaged in pumping and using chlorine-containing media. This alloy can also be supplied under other specifications — ASTM B 427 and DIN EN 1705.

Urgency of application

Bronze grade 2.1060 (C91700, CuSn12Ni) can be used in various ring and tubular structural elements, nuts under load, discs operating at considerable mechanical pressures. Such details include heavy-loaded worm wheels and screw-nut gears.

Load characteristics of worm wheels depending on the sliding speed 200… 1250 N / cm² or — for short-term loading — 4000… 4500 N / cm². The main operational characteristics of the material are high corrosion resistance at moderate strength.
